Persistence of COVID-19
Q: They say that freezing the virus doesn't make it go away, as a matter of fact, I've heard that that is how they store virus'. So if you buy something that others have touched (possibly with the virus) and then put it in your freezer, won't the virus survive and re-contaminate people when it comes out of the freezer?
It is unlikely that freezing by itself would be effective in inactivating COVID-19, however as detailed by the FDA, there is currently no evidence of food or food packaging being associated with transmission of COVID-19. It is extremely unlikely that any food or food packaging would be contaminated with viable virus that causes COVID-19. The time needed to freeze and thaw food and food packaging makes contamination with a viable virus even less likely. It is very important to wash your hands after returning home, before preparing food, and before consuming food.
There are occasional reports in the media about frozen food and food packaging (e.g. ice-cream, fish, and shrimp) testing positive for SARS-CoV-2. These reports lack detailed information about how food and packaging was tested; for example, did they test for traces of genetic material from the virus or presence of viable virus. This makes a large difference since genetic material can remain on the surfaces even after the virus is inactivated. In an unlikely scenario that actual viable virus is present on frozen food there is still a minimal risk of this virus causing infection. There is several reasons for this: (i) if present, the virus is present in low numbers (not sufficient to cause infection), (ii) sufficient numbers of the virus have to reach the receptors in your nose in order to cause infection; this is highly unlikely to happen during eating food, (iii) the virus will not survive transition through the stomach because of high acidity in the stomach. We are reaching 200 million COVID-19 cases globally and there is still no evidence to show food or food packaging can be involved in transmission of COVID-19. The main path of transmission are still close person-to-person contact with an infected person and respiratory droplets from an infected person. Mitigation strategies like vaccination, social distance of 6 feet, wearing proper face coverings, not touching your face, washing your hands and avoiding large gatherings are still the main strategies that will keep you safe from infection.
Scientific reports are indicating that standard pasteurization at 63⁰C for 30 min is sufficient to inactivate SARS-CoV-2 and similar viruses (e.g. SARS-CoV and MERS-CoV).
Scientific reports are indicating some dosages and wavelengths of UV can be effective against SARS-CoV-2 and similar coronaviruses, however the same studies are reporting that other wavelengths of UV and reduced dosages are completely ineffective. In order for UV to be effective it needs sufficient exposure time and is only effective if the virus is directly exposed to the radiation. This need for direct exposure and poor penetration of UV radiation can result in complete ineffectiveness if contaminants like dust and bodily fluids are present on the surface.
Use of UV in any application cannot be used as a standalone hurdle and cannot be used to replace any of the basic measures required to prevent the spread of COVID-19, including hand-washing, cleaning, chemical sanitizing, pasteurization, exclusion of ill workers from the work environment and social distancing.
UV light can represent a potential health and safety risk depending on the wavelength, dose and duration. The risk may increase if the unit is not installed properly or used incorrectly.
As detailed by CDC, conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or inactivate COVID-19. UV treatment of municipal drinking water is not necessary to assure absence of COVID-19.

Q: I heard some reports that COVID-19 can be transmitted though air; are aerosols generated by an infected person considered a risk?
The virus that causes COVID-19 is still relatively new and an unknown virus to us when it comes to understating all of the paths of transmission and how efficient individual paths of transmission are. The part that is also still relatively unknown to us is the infectious dose of this virus; that is how many viral particles you must be exposed to in order to get infected.
What we do know is that the virus is transmitted through respiratory droplets generated by infected people. Large droplets are thought to be the primary risk, as they carry a large number of viral particles. These large droplets are heavy, they tend to drop to the ground relatively quickly and generally travel less than 6 feet; which is why social distancing of 6 feet is recommended for reducing transmission, and also why cloth face coverings are recommend, to capture these larger droplets at the source.
When a person talks, coughs, or sneezes, small droplets that carry a small number of viral particles are also generated; these small droplets can remain in the air for longer and travel further away from the source. Currently, we don’t know how effective these small droplets are in supporting transmission of the virus. Based on information from hospital environments we know that small droplets generated during invasive procedures on COVID-19 patients represent an important risk for the hospital workers. During these invasive medical procedures, a majority of the large droplets (carrying more of the virus) are converted into a number of small droplets that together still carry a large number of viral particles that represent the risk of transmission. Generation of a large number of small droplets is not something we can expect outside of the hospital environment, which is the reason why many experts believe aerosolization is a smaller risk in everyday situations most people will encounter.
Even with the limited knowledge on some of the aspects of transmission we still have relatively complete information on what are the most effective strategies in preventing transmission. We know from countries and cities (i.e. New York City), which were strongly effected by COVID-19, that basic prevention measures like practicing social distancing, wearing face coverings, using hand sanitizer, and regularly washing hands with soap and water are very effective in reducing the spread of COVID-19. While other strategies might also be effective in reducing the spread, no scientific data is currently available that would suggest a higher effectiveness than these basic preventive measures or that any of these basic measures can be replaced or eliminated.
While ventilation, filtration, and UV systems may remove small droplets and potentially associated viral particles from the air, it is not clear that they would significantly reduce transmission in everyday settings. It is clear that none of these systems can replace the need for social distancing, face coverings, and regular hand-washing. If you are in close proximity to someone who is shedding the virus, an air handling system will not protect you. It is critical that individuals who are presenting symptoms associated with COVID-19 or are known to have COVID-19, stay home. For the rest of us, it is critical to practice social distancing to reduce our potential exposure to large droplets, and it is important for us to wear cloth face coverings in the event that we are asymptomatic or pre-symptomatic so that we do not unknowingly spread virus-containing respiratory droplets to others.
Currently there is no evidence of food or food packaging being associated with transmission of COVID-19, according to the FDA, CDC, and European Food Safety Agency (EFSA). The virus that causes COVID-19 does not have a protective protein coat which makes it very unstable outside of the human host. Because of poor survivability of this virus on surfaces, there is likely a very low risk of spread from food products or packaging. Unlike the virus that causes COVID-19, all known foodborne viruses (i.e. norovirus, hepatitis A) have a protective protein coat that allows them to survive on food, food packaging, and in the environment for extended periods of time.

Q: I heard that COVID-19 can travel in the air for 9 to 12 feet when someone coughs or sneezes; how can the CDC say that I am protected from infection if I'm only keeping a distance of 6 feet?
Water droplets generated when a person coughs or sneezes can be separated into two sizes; large water droplets which are more than 5 microns in size and small water droplets which are less than 5 microns in size.
Large water droplets can travel less than 6 feet from the source before either evaporating or settling down towards the ground, which happens in less than 5 minutes. According to the World Health Organization, 3 feet is already a sufficient distance beyond which the number of large droplets is so small that the quantity of viable virus carried in these droplets is too small to cause an infection. CDC recommends keeping a distance of 6 feet as an extra precaution in preventing the transmission of COVID-19. The distance of 6 feet also gives a person enough time to step away from the person coughing or sneezing which adds another layer of protection.
Small water droplets generated when a person coughs or sneezes do not drop to the ground. The majority of these small water droplets evaporate instantaneously; as comparison, a 50 micron water droplet will evaporate in less than a second at normal air temperature and humidity. COVID-19 virus can only survive inside a host and once it is in the environment the virus is inactivated at a fast rate. Inactivation of the virus is even faster when exposed to dehydration encountered during evaporation of small water droplets. Currently, there is no evidence that COVID-19 infection can be transmitted through air beyond 6 feet in a normal everyday environment. The possibility of airborne transmission was only shown in a hospital environment when invasive procedures are performed directly on COVID-19 patients that generate a lot of aerosols; for example, intubation.
Remember to always cover your mouth and nose when coughing or sneezing using a tissue or upper part of the sleeve; dispose of the tissue and afterwards, be sure to wash your hands for 20 seconds with soap and water. You should wear a cloth face covering if coughing or sneezing, especially if you're in public places and in situations where social distancing is not possible. You should also self-assess the coughing, sneezing or any other symptoms you might have and if necessary, seek advice from your local health provider.
COVID-19 is highly unstable outside of its host and the number of infectious viral particles is reduced at a fast rate as soon as it exits the host. Results of a recent study indicate that the reduction rates of COVID-19 on different surfaces are similar to that of the coronavirus SARS. The observed reduction rates, measured in half-life (time needed to reduce the number of active viral particles by half), were dependent on the type of surface. The longest observed half-life of COVID-19 was on plastic surfaces (7h), followed by stainless steel (5.5h). COVID-19 was much less stable on cardboard (3h) and copper (1h). COVID-19 also had a half-life of 1h when tested in aerosolized water droplets. The contamination of different surfaces with infectious viral particles used in this study was much higher than the contamination we would expect in everyday situations; the use of a high contamination load was necessary to allow the researchers to quantify and measure the half-life of the active COVID-19 viral particles. The expected low levels of surface contamination in everyday situations combined with fast inactivation rate of infectious viral particles results in a relatively short window after contamination in which viable viral particles are present on any surface. In order to prevent infection from touching surfaces within that small window after contamination, it is still critical that people:
- Maintain social distance; you are not just preventing transmission of COVID-19 from person-to-person but also maintaining a distance that will prevent you from touching recently contaminated surfaces around other individuals.
- Maintain proper hand hygiene; ideally washing your hands with soap and water for 20 seconds or if that is not available using the appropriate hand sanitizer. If you touch a contaminated surface this will inactive the virus.
- Not touch their faces. If you have touched a recently contaminated surface, keeping your hand from your mouth, nose, and eyes will help stop potential routes of infection.
It is also critical to maintain proper respiratory hygiene practices and wear a proper face covering when social distancing is not possible in order to reduce the risk of transmission from person-to-person as well as contamination of surfaces,.
Facilities should actively maintain routine, scheduled cleaning and sanitization of both production and non-production areas. Particular focus on high risk areas (restrooms, break rooms, locker rooms, first aid areas, etc) and surfaces (door knobs, hand-rails, telephones, faucets, electronics, etc) that employees regularly come in contact with, warrant cleaning and disinfection on a regular and frequent schedule.
We know that the virus is highly unstable outside of its host and is inactivated at a fast rate on any surface. A recent study showed that the number of viable virus particles on cardboard are reduced by half every 3 hours. Because of this fast rate of inactivation, there is likely a very low risk of spread from food products or packaging, especially when these products are shipped over a period of days or weeks. Transmission of COVID-19 occurs mainly from person-to-person through respiratory droplets and less likely through contaminated surfaces. There are no known cases of transmission through cardboard, and there is no recommendation for specific interventions to address transmission through cardboard. Although cardboard packaging is not recognized as a risk, it is still important to reinforce GMPs like washing your hands often, proper respiratory hygiene, and not touching your face when handling these types of items.
There are a number of pharmaceutical companies that are developing vaccines for COVID-19; there are currently three vaccines that received Emergency Use Authorization (EUA) and are currently being used in the US. There are also at least 28 other vaccines in advanced stages of testing around the globe.
Currently, we know that the three approved vaccines are effective at preventing the development of disease, which will substantially reduce the number of hospitalizations and deaths. The information that is currently still missing is how effective the three vaccines are at preventing the shedding of the virus; for example, the vaccine might limit the replication of the virus in the body and prevent development of the symptoms but still allow sufficient replication that the person starts shedding the virus and potentially infects others around them. This is the reason why, if not all employees are vaccinated, it is still recommended that people keep practicing all the essential mitigation strategies, including keeping a social distance of 6 feet, wearing face coverings, avoiding touching their face, avoiding crowded places, and regularly washing their hands.
It is essential at this moment that each member of the food industry takes the necessary steps to make sure all COVID-19 Control Strategies are in place, consistently followed, and compliance verified on all levels. The necessary steps also include (i) appropriate training of employees, (ii) regular verification of social distancing and correct wearing of face coverings, and finally (iii) ‘pressure testing’ the written procedures that describe what to do when an employee either tests positive for COVID-19, develops symptoms compatible with COVID-19, or is potentially exposed to the virus that causes COVID-19.
Q: Why do I still have to wear a face covering and keep my social distance even after being fully vaccinated?
The answer is because we still don’t know if vaccines can prevent transmission of the virus from vaccinated person to others; the only part we do know is that it can prevent development of COVID-19 symptoms.
We know vaccines are very effective at preventing COVID-19; the development of symptoms, need for hospitalization, and the likelihood of a person dying because of COVID-19. For example, the last vaccine that was approved in the US has about 72% effectiveness; this means that for every 100 cases of COVID-19 among people that did not get vaccinated we expect to see only 18 cases of COVID-19 among vaccinated people.
The part we currently don’t know is if vaccinated people that are exposed to the virus have only mild infection without symptoms, in which case they can spread the infection to others, or are they protected from infection all together, in which case they are also not spreading the infection to others. In other words we don’t know if vaccinated people after being exposed to the virus will become asymptomatic carriers of the virus and infect others. The risk of spreading the virus to other people is even greater if these vaccinated people adopt an attitude that they are safe and everyone else around them is safe from the infection.
Some of the new studies are showing promising results and indicating that vaccines are not only effective at preventing development of COVID-19 but also at preventing the transmission of the virus. However, these studies included only a limited number of people and a limited number of different vaccines, not enough to make general statements about the safety of all vaccines in all situations; for example, in different populations, ages, cultures, geographic locations. Because we cannot say with certainty that all vaccines prevent virus transmission in all situations, it is better to keep other control strategies even after we receive the vaccine, including wearing face coverings, keeping social distancing, frequently washing our hands, avoiding touching our face and avoiding public spaces and large gatherings.
As more people get vaccinated, the number of daily cases is further reduced, and we get more scientific data on vaccines, we will be able to gradually loosen the recommendations.
The important part to remember is that just because the recommendations are to keep practicing social distancing and wear face coverings even after being fully vaccinated, this does not mean that vaccines are not effective. As we said, the number of people that develop COVID-19 is expected to be reduced by at least 72% with vaccination.
What we want to achieve with vaccination is something called herd or community immunity, where not only vaccinated people are protected from COVID-19 but also people that cannot get vaccinated; for example people with chronic illnesses. Some estimations are that at least 80% of the population would have to be vaccinated in order to reach herd immunity. Currently, there has been approximately 33 million estimated infected people and 135 million fully vaccinated people in US, which is still less than 50% of the US population; there is still a lot more people that can get infected and continue the pandemic.
We can achieve herd immunity much faster with vaccine than without it and with it we get less deaths, less hospitalizations and we also give this virus less chance to spread, replicate and mutate into a variant that can cause an even bigger problem; for example, causes more severe illness or not be affected by our current vaccines. At the moment we do have vaccines that are effective, we also have other mitigation strategies that are effective and in place; we should use all possible strategies to regain control over this pandemic before we go back to complete normal.
Q: Is it safe to get the COVID-19 vaccine if there is a risk of severe allergic reaction to it? I know anaphylactic shock can kill you.
Although newly developed vaccines for COVID-19 can cause an allergic reaction in certain individuals, the chance of this happening is extremely low and usually occurs in people with a history of developing allergic reactions to other vaccines. Current available data on Moderna COVID-19 shows that there was only 10 reported cases of anaphylactic shock among more than 4 million people that received the first dose. In nine of these cases, the onset occurred within 15 minutes of vaccination; the person receiving the vaccine stays under the medical care for at least 15 minutes after receiving the vaccine. No anaphylaxis-related deaths were reported. The benefits of receiving a COVID-19 vaccine outweigh any risks associated with it; if you have any additional concerns with getting vaccinated consult with your doctor. Vaccination is an important part of the strategy to stop the COVID-19 pandemic; it is highly recommended that people that are able to receive the vaccine decide to do so to protect themselves and others around them.
Q: I offer an essential service that requires me to go to other businesses. How can I protect myself against COVID-19?
COVID-19 is spread mainly from person-to-person and through respiratory droplets produced when an infected person coughs or sneezes. The best ways to avoid the spread is to get vaccinated, clean your hands often, avoid close contact with others (maintain 6 feet of distance), wear face coverings and clean frequently touched surfaces.
Clean your hands often with soap and water for at least 20 seconds, especially after you have been in a public space. If soap and water are not readily available, you can use a hand sanitizer that contains at least 60% alcohol. Be sure to wash your hands and avoid touching your face, especially after touching frequently touched surfaces including tables, doorknobs, light switches countertops, handles, phones, keyboards, faucets, etc. You may consider bringing your own cleaner and disinfectant with you when traveling to different sites. This way you can disinfect frequently touched surfaces that you must come into contact with.
Q: I’m confused about CDC’s recommendations for when an employee can return to work; is it after 10 or 14 days?
To answer this question it is necessary to distinguish between two concepts: (i) how long does it take for a person to develop illness after being infected with the virus that causes COVID-19, (ii) once that person develops illness, how long will they be able to infect other people.
The majority of people will develop first symptoms 2 to 14 days after being exposed to the virus. Even if the person that was exposed to the virus does not develop any symptoms and remains asymptomatic it will take 2 to 14 days for the person to start shedding enough virus to (i) be infectious to other people, and (ii) to be positive when tested for the virus. A person that was recently infected with the virus will most likely not test positive for the virus; the virus needs to multiply to sufficient numbers in the body first. Because the majority of infected people will develop symptoms or test positive within 14 days, CDC recommendations are for a person that had close contact with COVID-19 positive person to ‘quarantine’ for 14 days after the last exposure. CDC updated the quarantine guidelines to include options to reduce the quarantine time to (i) 10 days without COVID-19 testing, or to (ii) 7 days with a negative COVID-19 test (sample for testing has to be taken on day 5 or later). The person has to keep monitoring the symptoms closely for 14 days even if the quarantine time was reduced. Talk to your local Department of Health to get information if any of the two options were adopted by your State regulation; for example, NY State only adopted the first option of reducing the quarantine to 10 days. Besides staying home during quarantine, a person should stay away from other people who are at higher-risk of developing COVID-19 and also closely monitor for any symptoms.
A person with COVID-19 will typically shed active viral particles, that can infect others, up to 10 days after the symptoms first started; CDC is referencing six different studies to support this information. CDC is recommending, based on this information, that a person with COVID-19 should ‘isolate’ them self for at least 10 days after the first symptoms occurred or after the first positive test. Make sure you are without fever for at least 24 hours (without the use of fever-reducing medications) and you don’t have any other symptoms before returning to work, regardless if it has been already 10 days since the symptoms first started. There are reports of some severe COVID-19 cases that were shedding active viral particles for 20 days, however these were rare occasions. A study on severe and critical COVID-19 cases, for example in immunocompromised patients, showed that approximately 15 days after the symptoms started the probability of detecting active viral particles in these cases was less than 5%.
A person that had close contact with an infected person might have to stay home and restrict from any interaction with other people for up to 24 days; it can take up to 14 days to develop illness and start shedding the virus, and up to 10 days to stop shedding the virus after the illness developed. If you think or know you had close contact with an infected person contact your local Department of Health for specific instructions on quarantine, isolation, and other procedures specific for your local area.
Q: A food service worker in my local fast-food restaurant is using a face shield instead of a face covering; are face shields equally effective at reducing the spread of COVID-19?
Face coverings were implemented in the US to prevent the transmission of COVID-19 by pre-symptomatic or asymptomatic people that don’t know they are infectious. The face covering works by blocking respiratory droplets when a person talks, sneezes, or coughs and protects other people from the person wearing the face covering.
When it comes to face coverings (i.e. N-95 respirators, medical masks, cloth face coverings including neck gaiters), we have good scientific data (i.e. on materials, designs, fitting to the face) that shows the effectiveness of different face coverings on blocking the respiratory droplets at the source. For example, cloth face coverings including neck gaiters are comparable to medical masks when it comes to blocking respiratory droplets at the source.
A CDC study on N-95 respirators, medical masks, face shields, cloth face coverings and neck gaiters, showed that face shields are only able to block 2% of the droplets at the source while cloth face coverings and double layered neck gaiters were able to block more than half of the generated droplets.
Face shields were also shown to not be sufficiently effective at protecting the person from respiratory droplets generated by other people if used by itself. In a hospital environment, face shields are considered an eye or face protective equipment and are recommended to be used in combination with actual respiratory protective equipment.
Our recommendation would be to use cloth face coverings or neck gaiters in any public setting, including food service and food processing. For maximum protection we would recommend using a face covering or neck gaiter in combination with a face shield.
Q: I am not able to maintain a social distance of 6 feet; does it make a difference if I keep a distance of 5 or 3 feet?
Social distancing is preventing several risk factors:
- Prevents physical contact with another person; considered to be one of the main risk factors.
- Prevents large respiratory droplets from reaching your face, mouth, nose and eyes when another person sneezes or coughs because these large respiratory droplets fall to the ground or land on surfaces within 6 feet; also considered to be a large risk factor.
- Prevents contact with surfaces that were recently contaminated with respiratory droplets by cough, sneeze or touch; because the virus is unstable outside of the human host only recently contaminated surfaces (like frequently touched surfaces) are considered a risk
If you keep a distance of 6 feet the risk of infection is still not zero, however it is low enough to be considered highly unlikely to happen. In the same sense, if you keep a distance of less than 6 feet this does not automatically mean that you will get infected; however, the risk of infection is high enough for CDC to consider it too high. The shorter this social distance is the higher the risk is; the closer you are the more large respiratory droplets can reach your face, nose, mouth and eyes, you are also in reach of more fresh respiratory droplets on surfaces, and more likely to come into physical contact with the other person. The same relation exists with time; the longer time you spend within 6 feet the higher the risk is.
If you are not able to maintain social distancing you should still do your best to reduce the risk as much as possible by maximizing the distance that you can keep and by minimizing the time when proper social distance of 6 feet is not maintained.
Face coverings can help reduce the risk by restricting the spread of some of the large respiratory droplets that could otherwise reach your face or land on surfaces. Where face coverings are less effective in reducing the risk is preventing the respiratory droplets that do reach your face from contaminating your face and eyes. Face coverings are also not effective at all in reducing the risk when it comes to touching contaminated surfaces, or touching another person; some might even consider face coverings an increased risk because a person wearing a face covering might be more likely to touch their face by frequent re-adjusting of the face covering.
Face coverings are not a replacement for social distancing and should be used together with proper hand-washing and avoiding touching your face.
Q: Food industry employee lives with a household member who is a health care worker and is treating COVID-19 positive patients; Can the food industry employee still come to work?
The primary concern here is transferring the virus to other employees at the facility, NOT contaminating the food. It is important to proceed in a manner that maintains the privacy of the employee, the suggested course of action is:
- Confirm the employee and their household have already implemented procedures to minimize risk of transmission at home recommended by CDC, NY DOH, or the health care facility the household member works for.
- You should consider to either monitor or ask the employ to self-monitor for symptoms (cough, fever >100.4 F, shortness of breath). If they begin to show symptoms, they should stay home and seek guidance from their health care provider.
- Ensure the employee is aware to confidentially contact management if their household member begins to present symptoms of COVID-19 or tests positive for COVID-19. If the household member tests positive for COVID-19, it is recommended to have the employee stay home and contact their public health provider.
- If you have employees whose household member works in healthcare, you may consider having them work from home.
Q: How do I encourage social distancing even though my employees work together every day and are very familiar with each other?
The exposure to COVID-19 can be greatly minimized by social distancing (maintaining 6 feet or greater distance). The key here is thinking that even though you work with the same people every day, you don’t know who they’ve been unintentionally exposed to when they are not at work. Social distancing can present a problem among employees because familiarity of workers tends to result in them dropping their guard. A conscious effort needs to be instituted and supervisors should be ensuring these practices are always happening. A training session of all employees should be initiated to encourage social distancing and provide the benefits of it. While the term is ‘social distancing’ it should be emphasized that social interaction between workers is allowed as long as it is done from a recommended safe distance of 6 feet.
Employees in food processing facilities should continue to follow good manufacturing practices such as frequent hand washing and good personal hygiene. If disposable gloves are worn as part of the routine procedures in an individual facility, employees must wash their hands before using the gloves. Gloves must be changed anytime they become contaminated, this includes anytime the gloves touch your face, hair and any filth. Hands should be washed before and after preparing food and gloves should be changed. It is important to recognize that gloves do not prevent cross-contamination and therefore by themselves do not prevent the spread of illness from one employee to another.
What to do When an Employee Tests Positive for COVID-19
If an employee or individual currently working, or recently present, within your facility is confirmed by a laboratory to be positive for COVID-19 or developed typical symptoms, including fever, cough, and/or shortness of breath, send them immediately home and notify your local health department. Ensure that all surfaces and areas that the positive individual came into contact with are immediately cleaned and disinfected. Your local health department will be involved in monitoring the employee or individual while symptomatic and under isolation until they recover. The local health department will also be involved in clearing fully recovered employees from isolation before they can return to work. An employee is considered fully recovered and may return to work under the following conditions as defined by CDC Interim Guidance:
- No fever for at least 24 hours without the use of medicine that reduces fevers
- No other symptoms, including cough and shortness of breath
- At least 10 days have passed since symptoms first appeared
If you have an employee that tested positive for COVID-19, you should identify employees who came into close contact with the positive individual during the period of 48 hours before the onset of symptoms and until fully recovered (see above). Have them contact their health care provider, and the local health department will provide further guidance on monitoring and segregation. If possible, have employees who came into close contact with the positive individual stay at home and have them request to be tested for COVID-19.
Close contact is defined by CDC Public Health Recommendations for Community as including:
- Any Household member
- Intimate partner
- Individual providing care in a household without using recommended infection control precautions
- Individual who was directly coughed on
- Individual who spent 15 minutes or more within 6 feet or less of the positive individual that did not wear a face mask to block respiratory secretions from contaminating others and the environment.
Contact with a positive individual is considered close contact regardless if face coverings were worn. If employees who came into close contact with the positive individual cannot be sent home, adhere to the following practices prior to and during their work shift:
- Pre-Screen: Employers should measure the employee’s temperature and assess symptoms prior to them starting work. Ideally, temperature checks should happen before the individual enters the facility.
- Regular Monitoring: As long as the employee doesn’t have a temperature or symptoms, they should self-monitor under the supervision of their employer’s occupational health program.
- Wear a Mask: The employee should wear a face mask at all times while in the workplace for 14 days after last exposure. Employers can issue face masks or can approve employees’ supplied cloth face coverings in the event of shortages.
- Social Distance: The employee should maintain 6 feet and practice social distancing as work duties permit in the workplace.
FDA and CDC allow the use of cloth face coverings instead of N-95 respirators which are still considered critical supplies that must continue to be reserved for healthcare workers and other medical first responders.

Q: Should I have all of my employees vacate the processing facility if one of my employees tests positive for COVID-19?
Current guidelines from the FDA and NYS Department of Health do not include having employees vacate the facility after a COVID-19 positive case in a Food Manufacturing Facility. The only recommendations in this situation are to immediately send employees who test positive for COVID-19 home and perform cleaning and disinfection of all surfaces throughout the area and contact your local health department.
CDC guidelines on cleaning and disinfection of facilities are recommending closing off areas visited by the ill persons and to wait 24 hours or as long as practical before beginning cleaning and disinfection. CDC states that these guidelines are NOT to be followed when specific guidance already exists. Food Manufacturing Facilities have specific guidance set by the FDA and State Health Departments when a COVID-19 positive employee is identified, and these are the guidelines that should be followed. It is particularly important to follow these guidelines and NOT the CDC guidelines when it comes to opening the outside doors and windows to increase air circulation in the area; there are other food safety risks associated with outside environment.
The only example where Food Manufacturing Facilities might consider having their employees vacate an area of the processing facility is when a COVID-19 positive employee or an employee with all typical COVID-19 symptoms, including cough, fever and shortness of breath, was working in a room or a small area for prolonged time.
It is unknown how long the air inside a room occupied by someone with confirmed COVID-19 remains potentially infectious. Facilities will need to consider factors such as the size of the room and ventilation system design when deciding how long to close off the room or area used by the ill person before beginning the cleaning and disinfection. Taking measures to improve ventilation in an area or room, without opening the outside windows or doors, will help shorten the time it takes respiratory droplets to be removed from the air.
No, because there is no evidence that suggests COVID-19 is transmitted through food consumption, according to the FDA, CDC, and European Food Safety Agency (EFSA).
The primary goal is to prevent person-to-person transmission. Therefore, if an employee is confirmed to have COVID-19, employers should inform fellow employees of their possible exposure to COVID-19 in the workplace but maintain confidentiality. Sick employees should follow the CDC’s ‘What to do if you are sick with coronavirus disease 2019 (COVID-19)’. Employers should consult with the local health department for additional guidance.
- CDC – What to do if You are Sick with Coronavirus Disease 2019 (COVID-19)
- FDA – Frequently Asked Questions
- FDA – Briefing for Foods Stakeholders on Coronavirus Disease 2019 (COVID-19)
Normally, employers are prohibited from asking about an employee’s health status based on a series of anti-discrimination laws. However, in a time of pandemic illnesses, the Equal Opportunity Employment Commission (EEOC) has established a regulatory guidance that allows employers to adopt different policies that would normally not be allowed. This page from EEOC provides a series of short answers and a recorded webinar that provides employers with specific guidance. Employers may adopt a policy requiring employees to notify them about a positive COVID-19 test, and employers may also require employees to have their temperature taken upon entering the workplace. The CDC has also issued guidance about public health measures to protect your essential workforce which you can find here.
Q: There are a lot of different recommendations on cleaning, sanitation, and disinfection out there when it comes to COVID-19; what are the recommended procedures for Food Processing Facilities?
Food processing facilities must follow Current Good Manufacturing Practices (CGMPs) and the FSMA Final Rule for Preventive Controls for Human Food, which include maintaining clean and sanitized facilities and food contact surfaces. These rules are the base for manufacturing safe food regardless of the COVID-19 pandemic. Food facilities are required to use US EPA-registered “sanitizer” products in their cleaning and sanitizing practices. FDA Food Code defines “sanitizer” as a substance, or mixture of substances, that reduces the bacterial contamination of inert objects or articles, or equipment and utensils, and other cleaned food-contact surfaces by at least 5 log units, which is equal to a 99.999% reduction. Sanitizers for food-contact surfaces or Sanitizing Rinses are formulated in a way to be used without rinsing; the chemical residues on the food-contact surface are below the level that would represent a hazard for the consumer if these residues were to be transferred to food.
By definition sanitizers are only effective against bacteria while disinfectants on the other hand can by definition be active against bacteria, fungi and/or viruses, but typically not against bacterial spores in a food processing setting. Activity against viruses is the reason why FDA and most likely your local health department, i.e. NYS Department of Health requires you to perform disinfecting of specific surfaces after cleaning. This is:
- Before a confirmed case of COVID-19 occurs: Routinely clean high-risk locations (i.e. dining areas, and frequently touched surfaces like doorknobs)
- When a confirmed case of COVID-19 occurs: Clean and disinfect ALL surfaces including food-contact surfaces that the positive individual came into contact with over the last 24 hours of showing symptoms or testing positive.
For any given product registered as a disinfectant, data must be generated and approved by the US EPA for specific organism claims; for example, some disinfectants may only be approved to be used against a subset of bacteria, fungi or viruses. Review the US EPA webpage, product specifications and product labels for details on activity of each disinfectant product. Use List N of EPA-registered disinfectants to find products considered to be effective against COVID-19 based on the emerging viral pathogen program or because they already have claims against similar human coronavirus(es). All products on this list meet EPA’s criteria for use against COVID-19, including those marked as “No” under “Emerging Viral Pathogen Claim”. Look for products that can be used in “Institutions” on “Hard nonporous” surfaces.
Disinfectants often contain the same chemistry as sanitizers but at a higher concentration. While this higher concentration of active ingredient in disinfectants can be used in some applications on non-food-contact surface without rinsing, this will not be true for most applications on food-contact surfaces. After disinfection of food-contact surfaces these surfaces need to be properly rinsed with water. Because potable water used for rinsing is not sterile, you must sanitize the food-contact-surfaces before using them for processing food.
Although by definition only disinfectants can be effective against viruses there are also sanitizers that at no-rinse concentration, may be effective against viruses, including viruses that are more stable than COVID-19. The process of registering such products as ‘Sanitizers with virucidal activity’ is currently ongoing at EPA. Currently, in order to perform inactivation of COVID-19 on surfaces, all products need to be used at concentrations and the dwell time on their label to be appropriate for disinfection.
General recommendation would be to use a product that has both food-contact sanitizing claims and disinfectant claims (these will likely be at different active ingredient concentrations). However, it is very important to always consult with your chemical supply company on what products can be used in food processing facilities on food-contact and non-food-contact surfaces against COVID-19. It is also very important to consult with them on how to use these products since the language for disinfecting food-contact surfaces is inconsistent across labels for different products.
In the 2005 FDA Food Code, the use of the term “hand sanitizer” was replaced by the term “hand antiseptic” to eliminate confusion with the term “sanitizer,” a defined term in the FDA Food Code.
Overview of recommended procedures:
Did you have a COVID-19 positive case?
Is it a food production related surface?
Is it a Food-contact surface?
|NO||NO||YES2||Clean > Sanitize|
|NO||YES||YES4||Clean > Sanitize|
|YES||NO||NO1||Clean > Disinfect|
|YES||NO||YES2||Clean > Disinfect > Rinse > Sanitize|
|YES||YES||NO3||Clean > Disinfect|
|YES||YES||YES4||Clean > Disinfect > Rinse > Sanitize|
- 1For example, surfaces not related to food production would be found in restrooms, dining areas, locker rooms, and Frequently Touched Surfaces like doorknobs.
- 2For example, kitchen counters, inside of a refrigerator, utensils.
- 3 For example, floors and walls in the production room, exterior of equipment, food carts.
- 4 For example, conveyor belts, inside of a mixing kettle, slicers.
Q: Our processing plant has a COVID-19 Control Program in place; how do we know this program works and is sufficient to protect the workers from COVID-19?
Up to this point, the majority of food processing companies have managed to continue operations without having a single positive case among employees. As we enter the fall/winter season and the number of positive cases continue to increase across the country, it is very likely that some of these companies will at one point have to deal with a positive case among their employees. For example, the current daily average in New York is 4,500 cases (11/19/20), which means that a processor with 100 employees can expect to have two positive employees in the next three months. A functional COVID-19 Control Plan is what will make a difference between preventing or propagating the spread of COVID-19 from a positive employee.
What each company can do, before the first cases are identified among employees, is to ‘Pressure Test’ the COVID-19 Control Program they have in place and identify the weak points in the program that can increase the risk. The same way companies are performing mock recalls to make sure everything is in place for when the real recall happens, the companies can stage different positive case scenarios and follow the individual steps of the control plan being performed.
Some examples of staged scenarios that can be used as ‘Pressure Tests’ would be:
- A specific employee calls in and reports they are experiencing symptoms consistent with COVID-19.
- A specific employee walks to the production manager and reports that they just found out that they tested positive for COVID-19.
- A specific employee talks to a co-worker on the line about his or her partner (or child) having COVID-19.
- A specific employee acts out coughing or loss of taste during lunch.
Some of the questions that the company should address in the steps that follow this staged event of the ‘Pressure Test’ are:
- How are positive tests, symptoms, and potential close contacts initially handled and how effectively is this information communicated to appropriate staff responsible for COVID-19 Control?
- What are the instructions given to the positive employee about what to do and who to contact next?
- How is the positive employee, as the main risk of transmission, removed from the food processing plant?
- How is the potential shortage of employees addressed to facilitate uninterrupted production?
- When and how is the information about potential close contacts in the processing plant and other key information collected from the positive employee?
- How is the information about potential close contacts used to inform the steps to follow after the positive employee is removed from the processing plant (e.g., screening, cleaning, quarantining, etc.)?
- How are other employees and company management informed of the positive employee?
- What was the plan for contacting government agencies about the positive employee? (IMPORTANT: Make sure the key person responsible for contacting any government agencies is aware of the ‘Pressure Test’ and staged scenario).
- How is the privacy of the positive employee protected during entire process?
- Are other aspects of the operation, like procedures that assure safety and quality of the food, maintained unaffected during the entire process?
The information collected during this type of ‘Pressure Test’ should be used to identify the weaknesses, define the roles individual employees have, introduce additional steps if needed and update the overall COVID-19 Control Plan. Performing a ‘Pressure Test’ will also address the COVID-19 fatigue, people are experiencing after nearly a year of this pandemic, and also represent a record of the company’s commitment to protecting its employees and consumers.
Q: Should I modify how HVAC is operated and maintained in my facility to reduce the risk of spread of COVID-19?
The epidemiology of COVID-19 indicates that most infections are spread through close contact, not airborne transmission. According to the CDC, airborne transmission of the virus that causes COVID-19 is highly unlikely and can only occur under special circumstances and does not require any special engineering controls. Proper social distancing of 6 feet is sufficient to prevent transfer of infection from person-to-person by physical contact as well as airborne droplets. A functional HVAC system already in place as part of your GMPs is additionally reducing the risk of transmission through airborne droplets. There is no need to modify any part of your HVAC system including any change to the frequency of replacing the filters and other preventative maintenance. Verify proper SOPs for maintaining the HVAC system are in place and followed. This is also a good time to make sure all of your basic prevention strategies are in place including establishing a system of verifying compliance with these strategies.
Although contaminated surfaces are not the main way COVID-19 spreads, employees still need to be careful when it comes to recently contaminated surfaces like used dishes and utensils. Employees that are washing or otherwise handling the used dishes and utensils should be very diligent about not touching their face and regularly washing their hands.
Employees should also follow the CDC and FDA guidelines and use gloves when handling any used dishes, cups/glasses, or silverware. If possible, disposable gloves should be used and discarded after use. If reusable gloves are used, those gloves should be dedicated for handling dishes and utensils and should not be used for other purposes. Hands should be washed before and after using gloves.
Wash the dishes and utensils in a 3-compartment sink or a dishwasher using appropriate detergent and hot water. The dishwasher should be able to reach a temperature of 165⁰F if chemical sanitizer is used for the final rinse, and 180⁰F if high temperature and two-phase dishwasher are used to sanitize the dishes and utensils after washing. Although used dishes and utensils might be considered frequently touched surfaces, they are still food-contact surfaces and should not be treated with chemical disinfectants. Consult with your chemical supplier on appropriate sanitizer to be used on dishes and utensils.
Because of the high water temperature used during dishwashing and also because of the high dilution factor occurring during this process we believe transmission through generated mists and droplets is a very unlikely scenario. Employees should still avoid generating unnecessary splashes, droplets and mists during dishwashing.

Risk Assessments performed by FDA, CDC, European Food Safety Agency (EFSA) and other agencies around the world suggest that COVID-19 is not transmitted through food consumption. This information can be included in your Risk Assessment if you wish to update your Food Safety Plan. However, with the extremely low food safety risk and the low risk to the consumer (supported by USDA and FDA position documents that state that COVID-19 is not foodborne) there is no need to make any modifications to your current Food Safety Plan.
The primary risk with COVID-19 is transmission from person-to-person. Hence, make sure you have a strategy in place to reduce this type of risk to the employee, including (i) an SOP for cleaning and sanitizing frequently Touched Surfaces (with an associated list of frequently touched surfaces covered by this SOP), and (ii) an SOP for procedures to follow when employee is tested for and/or tests positive for COVID-19. Visit this page to find an example of a Food Facility COVID-19 Strategy Checklist and additional resources.
This is good time to remind your employees to keep practicing social distancing, frequently wash their hands, avoid touching their face, cover their mouth and nose with a handkerchief or a sleeve when sneezing or coughing, and to stay home if they have any symptoms.

Q: I’ve implemented a new procedure to more frequently sanitize frequently touched surfaces (e.g., door knobs) in my facility to prevent person-to-person spread of COVID-19. Do I have to clean these surfaces every time before I use a sanitizer on them?
Frequently touched surfaces, such as doorknobs and light switches, represent potential transfer points of contamination between individuals that are otherwise practicing currently recommended social distancing of minimum 6 feet. Hence, it is important to identify these potential transfer points in the production facility and develop and implement SOPs or protocols to assure that these points are cleaned and sanitized with enhanced frequency.
Our suggestion is to have a separate procedure/SOP for “Enhanced sanitation of frequently touched surfaces to prevent person-to-person spread of COVID-19”, which is distinct from routine SSOPs that are already in place. If surfaces are smooth and impervious with no apparent accumulation of soils, enhanced sanitation of these surfaces can occur without prior cleaning. However, it is essential that regular routine cleaning and sanitation of these frequently touched surfaces continues as specified in the SSOPs. Importantly, cleaning of these surfaces still needs to occur when the regular (non-enhanced) cleaning is performed.
For further information, we have developed a Food Facility COVID-19 Strategy Checklist page that includes a list of Frequently Touched Surfaces in a processing plant and general guidance for cleaning and sanitizing of these surfaces.
In most cases cleaning and sanitizing supplies can still be used after the expiration date however this depends on the type of chemical and the time since it expired. You should always consult with your supplier to make sure the chemicals are still preforming as intended and for the ways of testing activity.
It is strongly recommended to not delay your scheduled Preventive Maintenance. Make a plan of how to prioritize different parts of Preventive Maintenance based on your experience and risk and consult with an expert on your final plan.
Anytime there is a substitution or change in formulation, the food safety of your product should be evaluated, as inherent food safety characteristics may have changed. Changes in formulation should be reviewed by a process authority. Anytime you want to use an ingredient that is close or past the expiration date you also need a process authority review. Our team can provide process authority services in case you need to change processes and/or formulations due to COVID-19 related challenges. For more information visit the Cornell Food Venture Center and for dairy-related process authority services contact Rob Ralyea. For those outside of New York, the Association of Food and Drug Officials has assembled a list of food process authorities around the country by state and territory. It can be found here. If you have problems getting help, contact us and we will attempt to assist.
Q: May an employer administer a COVID-19 test (a test to detect the presence of the COVID-19 virus) before permitting employees to enter the workplace?
The Americans with Disabilities Act requires that any mandatory medical test of employees be "job related and consistent with business necessity." Applying this standard to the current circumstances of the COVID-19 pandemic, employers may take steps to determine if employees entering the workplace have COVID-19 because an individual with the virus will pose a direct threat to the health of others. Therefore an employer may choose to administer COVID-19 testing to employees before they enter the workplace to determine if they have the virus.
Consistent with the Americans with Disabilities Act standard, employers should ensure that the tests are accurate and reliable. For example, employers may review guidance from the US Food and Drug Administration about what may or may not be considered safe and accurate testing, as well as guidance from CDC or other public health authorities, and check for updates. Employers may wish to consider the incidence of false-positives or false-negatives associated with a particular test. Finally, note that accurate testing only reveals if the virus is currently present; a negative test does not mean the employee will not acquire the virus later.
Based on guidance from medical and public health authorities, employers should still require – to the greatest extent possible – that employees observe infection control practices (such as social distancing, regular hand-washing, and other measures) in the workplace to prevent the transmission of COVID-19.
Q: Are water fountains that my employees use a risk for transmission of COVID-19; what would be considered the best practice when it comes to water fountains?
According to the CDC (Water, Sanitation, and Hygiene (WASH) Team, Community Interventions Task Force, COVID-19 Response), there is currently no specific recommendation to shut down water fountains. Water fountains are considered high-traffic, high-touch surfaces, so they should be cleaned and disinfected on a regular basis (e.g., daily), and possibly more frequently with high use. Consult your chemical supplier on cleaning and disinfection products and methods that are both effective and appropriate for the device, and that conform to the device manufacturers’ directions. Frequently touched surfaces on a water fountain that should be cleaned and disinfected may include handles, knobs, basins, and water spigots. No-touch fountains should also be cleaned and disinfected the same as for conventional water fountains. COVID-19 virus has not been detected in drinking water, and there is no evidence to show transmission from water fountains or from drinking water. Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should be sufficient to remove and inactivate this virus which is known to be highly unstable outside of the human host.
Additional recommendations for using common, high traffic water fountains may include:
- Do not use the water fountain for washing hands or any other items.
- Do not spit water back into a water fountain.
- Use a single-use cup to collect the water.
- Water fountains used by children may need to be disinfected more frequently. Children should be instructed on the proper way to use water fountains.
- Follow social distancing recommendations of at least 6 feet and do not congregate around water fountains.
- Wear a cloth face covering when in public and near fountains where other people may be present.
- Pay attention to how your cloth face covering is removed before and re-adjusted after drinking the water in order to prevent touching your mouth, nose or eyes with unwashed hands.
- Wash your hands (for at least 20 seconds with soap and water) after touching a water fountain.
- Post signage near water fountains to encourage wearing a cloth face covering, social distancing, hand hygiene, and how to properly use the water fountain.
No. Currently there is no evidence of food or food packaging being associated with transmission of COVID-19. COVID-19 is a respiratory virus, most likely to be transmitted person-to-person. This is unlike foodborne viruses we normally talk about in produce (e.g., Norovirus, Hepatitis A) which spread easily through the fecal-oral route.
It is important to remember that eating fresh fruits and vegetables as part of a normal diet is beneficial to overall health. Fresh produce helps provide nutrients that are key to maintaining proper body weight and preventing chronic illnesses like diabetes.
Q: What are appropriate practices regarding COVID-19 in social distancing and sanitation, with respect to transporting farm workers between farm sites?
CDC defines social distancing as remaining out of congregate settings, avoiding mass gatherings, and maintaining distance (approximately 6 ft or 2 meters) from others when possible. It may be hard to fully implement these practices on a bus, but employees should avoid sitting close to other passengers and when possible, sit a seat apart. Enter only from rear doors to maintain a safe distance from the driver or have the driver step off the bus and passengers enter/exit one at a time to avoid close contact. The FDA has acknowledged that complete social distancing may not be possible in all work scenarios and facilities, but it is important to remain vigilant in practicing good hygiene, like hand-washing, that have always been key to safe food handling and processing. Additional steps such as wearing cloth face coverings is also an option, but does not remove the need to maintain a distance of at least 6 feet.
Sanitation practices should focus on surfaces frequently touched by employees and drivers. These surfaces likely include windows and mechanisms to lower and raise them, seat belts, the steering wheel, button or handle to open doors, and the seats themselves. Developing a protocol to clean and sanitize these surfaces will reduce the spread of contamination.

Q: How can I reduce the risk of spreading SARS-CoV-2, the virus that causes COVID-19 at my farm stand?
First, consider implementing practices that encourage customers to implement social distancing while they are on the farm. This could mean putting signs up to instruct customers to stay at least 6 feet apart or placing tape on the ground so when customers are waiting to check out, they will stay at least 6 feet apart. You can also encourage the use of cloth face coverings to reduce the likelihood that asymptomatic carriers will spread the virus while they are working or shopping. Many customers may be concerned about other customers touching produce before they buy it. Even though there is no research to indicate that SARS-CoV-2, the virus that causes COVID-19, can be transmitted through food, farms may consider limiting customers touching produce. In a farm stand scenario, farms could move to customers pointing to which produce they would like to purchase and a farm stand employee packing it for them. This would increase interpersonal interactions, making social distancing a challenge, so that needs to be considered.
First, follow your state and federal government guidance on changing work place policy recommendations for how many people can congregate at specific events and locations. Next, modify your current visitors’ policy to include social distancing practices. This means encouraging visitors to stay at least 6 feet away from others. Consider encouraging visitors to wear cloth face coverings, but it is important to make it clear that cloth face coverings do not reduce the need for social distancing. As always, instruct visitors to stay home if they are sick. Be clear that no one with signs and symptoms of any illness is allowed to enter your farm. Identify where toilets and hand-washing facilities are located, encourage visitors to use the facilities often, and share any other visitor policies that you have in place.
Meat & Seafood-related
As detailed by the CDC, there is no evidence to suggest that any animals, including pets, livestock, or wildlife in the United States, might be a source of COVID-19 infection at this time. There is also currently no evidence to suggest that imported animals or animal products pose a risk for spreading COVID-19 in the United States.
Q: I’m screening my employees for COVID-19; is this information considered a medical record? How long do I have to retain the documents if they are considered medical records?
Visit this page from Matrix Sciences to find a good overview of what is considered a medical record and what the requirements are for retention of medical records.
There are a number of web pages dedicated to tracking the development of the COVID-19 pandemic. You can visit our Tracking COVID-19 page where we offer links to COVID-19 trackers that we found useful during our work. Some COVID-19 trackers are focusing on a global scale where you can find information on the number of cases and deaths in individual countries; for example, this COVID-19 tracker from Johns Hopkins. Each of the US States is collecting data on number of cases, hospitalizations, deaths, and often times number of tests performed in each State. This data is offered and updated daily by at least one COVID-19 tracker in each US State. Most of these trackers are offering sufficient granularity to determine the changes in numbers in individual counties as well as major cities; for example, two separate COVID-19 trackers from the New York State, Department of Health are offering information for both New York State and New York City. You can visit our Tracking COVID-19 page to find COVID-19 trackers for all US States. Most of the trackers are offering different ways of displaying the information; for example, daily trends vs. total numbers displayed in different table, figure, and map formats. These tools can be very helpful for processors to know and predict the impact on their production by following the numbers in specific communities where their processing plant is located and where employees live; for example, by knowing that an employee with otherwise mild symptoms (i. e. absence of fever) is coming from a community with a recent increase in number of cases, a processor might decide on the side of caution and ask the employee to stay home. Processors should appoint a COVID-19 point person or a team within the organization to track COVID-19 development daily in relevant communities as part of the overall COVID-19 communication and coordination.
Q: Can I expect to see financial relief provided to small and large scale food processing businesses and farms?
State and national governments are enacting numerous COVID-19 economic relief programs, and information in this area is changing rapidly. The federal government recently added New York State to its listing of declared national disaster areas, making businesses eligible for low interest to no interest loans here. While most of the immediate focus on disaster assistance has been to immediately unemployed personnel and various extensions of tax due dates and certain loan or debt payment extensions, the general consensus among elected leaders seems to be that some form of business assistance programs should be developed particularly for hard-hit sectors of the economy. Cornell CALS recommends following the latest news from your elected officials or the trade organizations pertinent to your sector for the most up to date information on business relief packages. In general, financial relief packages for businesses and residents tends to be provided by the federal government. Here are some helpful resources for you:
