The COVID-19 virus, which is a respiratory illness that typically spreads via airborne droplets, can also be transmitted by touching a contaminated surface and then touching one's mouth, nose, or eyes. While there is no evidence of food, food containers, or food packaging being associated with transmission, the virus can survive on plastic for up to three days. The amount of virus detectable on a surface reduces with time, and factors such as temperature and humidity also play a role in how long the virus can survive.

What You'll Learn
The virus can last on plastic for up to three days
The COVID-19 virus can survive on plastic for up to three days. It is important to note that the virus's lifespan on a surface depends on several factors, including temperature, humidity, and surface type. For instance, the virus can last on cardboard for about 24 hours, on copper for four hours, and on stainless steel for two to three days.
The virus's ability to survive on surfaces for extended periods underscores the importance of practicing good hygiene and sanitation. While surface transmission is not the main way the virus spreads, it is still possible for a person to contract COVID-19 by touching a contaminated surface and then touching their mouth, nose, or eyes. Therefore, it is crucial to follow the CDC's guidelines on frequent handwashing with soap and water for at least 20 seconds and regularly cleaning and disinfecting surfaces.
Additionally, when handling food packaging, it is recommended to wash your hands before and after removing food from the packaging and before eating. This is especially important for high-risk and elderly individuals, as takeout and drive-thru meals may pose a risk of contamination, although there is currently no evidence of food, food containers, or food packaging being associated with COVID-19 transmission.
To effectively disinfect surfaces, it is recommended to use products that meet the EPA's criteria for use against SARS-CoV-2, such as diluted household bleach solutions or alcohol solutions with at least 70% alcohol. By following these precautions and staying informed about the latest guidelines, we can help reduce the spread of COVID-19 and protect ourselves and others from infection.

The virus's lifespan depends on temperature and humidity
The coronavirus can survive on plastic food containers for up to three days. However, the virus's lifespan on surfaces depends on various factors, including temperature and humidity.
A study published in Business Insider India found that an 18-degree Fahrenheit jump, from 68 degrees to 86 degrees, reduced the lifespan of SARS on steel surfaces by at least half. The study was conducted in a room at 70 degrees Fahrenheit and 40% relative humidity.
Another study published in Business Insider compared the drying time of coronavirus droplets at two different temperatures: 25 degrees Celsius (77 degrees Fahrenheit) and 40 degrees Celsius (104 degrees Fahrenheit), both with 50% humidity. The study found that the 15-degree increase halved the time it took for the droplets to evaporate.
The authors of the second study also observed that an increase in relative humidity from 10% to 90% increased the evaporation time of a droplet almost sevenfold when the temperature was kept at a steady 25 degrees Celsius.
According to Prof Kampf of the Institute of Hygiene and Environmental Medicine at Greifswald University Hospital, "Low temperature and high air humidity further increase [the virus's] lifespan."
Therefore, higher temperatures and lower humidity shorten the lifespan of coronavirus droplets on surfaces.

The risk of transmission via food packaging is incredibly low
The risk of transmission of COVID-19 via food packaging is incredibly low. While it is possible for the virus to survive on surfaces, it is not the main way the virus spreads. COVID-19 is a respiratory illness, and it typically spreads via airborne droplets from an infected person's cough or sneeze. These infected droplets can land on someone else's nose or mouth or be inhaled.
Research has shown that the coronavirus can survive on plastic for up to three days. However, the amount of virus detectable on a surface reduces sharply with time, with the virus becoming significantly less infectious over time. For example, the virus can only survive on cardboard for about 24 hours, and on copper for about four hours.
To protect yourself, it is important to follow the four key steps of food safety: clean, separate, cook, and chill. Wash your hands regularly, especially after handling food packaging, and disinfect surfaces with products that meet EPA's criteria for use against SARS-CoV-2. Additionally, follow guidelines to prevent the spread of COVID-19, including getting vaccinated and boosted, social distancing, and wearing a mask.
By following these precautions, the risk of transmission via food packaging can be further minimized, making it an incredibly low-risk source of infection.

The virus can be spread by touching a contaminated surface
The virus that causes COVID-19 can be spread by touching a contaminated surface and then touching your mouth, nose, or eyes. However, this is not the main way the virus spreads. The virus typically spreads via airborne droplets when an infected person coughs or sneezes.
The virus can survive on surfaces for varying lengths of time, depending on the material of the surface and the surrounding temperature and humidity. On plastic, the virus can survive for up to three days, although some sources suggest two to three days. The amount of virus detectable on a surface reduces sharply with time, with significantly less infectious virus present on cardboard, for example, in as little as four hours.
To protect yourself from the virus when handling objects or surfaces that may be contaminated, it is important to practice good hand hygiene. Wash your hands regularly, especially after opening packages or handling food packaging. Wash your hands for at least 20 seconds with soap and water, or use hand sanitiser with at least 70% alcohol.
In addition to hand hygiene, it is important to clean and disinfect surfaces regularly. The CDC defines cleaning as the removal of germs, dirt, and impurities from surfaces, while disinfecting involves using chemicals to kill pathogens on surfaces. The Environmental Protection Agency (EPA) has a list of disinfectant products that meet their criteria for use against SARS-CoV-2, the virus that causes COVID-19. These products can be used to disinfect surfaces in your home or other spaces.

Wash your hands after handling food packaging
It is important to wash your hands after handling food packaging. The coronavirus can survive on plastic food containers for up to three days. While there is currently no evidence of food, food containers, or food packaging being associated with the transmission of COVID-19, it is possible to contract the virus by touching a contaminated surface and then touching your mouth, nose, or eyes.
The coronavirus is a respiratory illness that typically spreads via airborne droplets from an infected person's cough or sneeze. When these droplets land on surfaces, the virus can remain viable for hours or even days, depending on the material of the surface. For example, the virus can survive on cardboard for up to 24 hours, on glass for up to four days, and on stainless steel for two to three days.
To protect yourself from potential contamination, it is recommended to wash your hands regularly with soap and water for at least 20 seconds. This is one of the most effective ways to reduce the chances of contracting the coronavirus. Additionally, it is important to clean and disinfect surfaces frequently, especially those that are frequently touched, such as food packaging.
By following these simple steps of handwashing and surface disinfection, you can significantly reduce the risk of contracting the coronavirus through contact with contaminated food packaging. Remember to also follow other preventive measures such as social distancing, wearing masks, and getting vaccinated and boosted when applicable.
