COVID-19 and food: What you need to know

The COVID-19 pandemic poses major challenges for the food industry. Securing the food supply to the world’s population must be guaranteed, even when there’s a risk of infection and during lockdowns. At the same time, the requirements in terms of hygiene, food safety and occupational health and safety have to be optimized constantly.

Learning from the past

The lockdown at the end of March 2020, which affected a third of the world's population, made interaction between food producers, logistics, retail and the restaurant trade more difficult. In some supermarkets, consumers were faced with empty shelves. Most restaurants were closed all over the world, and only take-away or delivery services remained in operation. This situation could recur at any time and all those involved need to be prepared.

Meeting the responsibility

Safe food
Food safety authorities around the world are investigating how the virus behaves in relation to food. They are also analyzing possible transmission routes. The aim is to prevent the virus from spreading between producers, retailers, caterers and consumers. So far (as of: September 2020), the transmission of SARS-CoV-2 through food has not been proven. However, this does not absolve the food industry from taking safety measures when it comes to the production and sale of food in order to avoid overburdening the healthcare systems.

Impact on productivity and occupational health and safety

The pandemic has rapidly changed the output and occupational safety requirements in food production and processing plants:

  • Retrofitted Plexiglas shields have to be disinfected and swabbed for the presence of airborne pathogens.
  • Additional testing and disinfection measures, including monitoring and data collection, result in delays which have a negative impact on productivity 
  • New evidence regarding COVID-19 among employees must be provided and documented
Occupational health and safety for food

These steps can be taken by companies in the food sector to ensure compliance with record-keeping requirements:

  • Collect timely, accurate data on employee health and safety 
  • Comply with the guidelines of local authorities and the WHO
  • Monitor compliance with the new protocols

6 insights related to food and COVID-19


The information shown reflects the current scientific information (September 2020). Please note that the COVID-19 pandemic and insights related to transmission of the virus are rapidly evolving.

Lifetime of the virus on packaging

The COVID-19 virus can survive for up to 72 hours on plastic and up to 24 hours on cardboard. The tests were carried out under laboratory conditions with controlled relative humidity and temperature, and should therefore be interpreted with caution in a real setting. (van Doremalen et al., 2020)

Cooking temperatures (> 70 °C) kill the virus

Scientific studies show that SARS-CoV-2 is inactivated after 5 minutes of incubation at 70 °C (Chin et al., 2020). Thus, normal cooking temperatures (> 70 °C) are sufficient for virus inactivation.

Virus survives freezing temperatures

Studies show that SARS-CoV-2 is highly stable at 4 °C. It is also expected to show similar behaviour to its predecessors at freezing temperatures, i.e. it could remain infectious at -20 °C for up to 2 years. (WHO)

Virus transmission through raw food

There is currently no scientific evidence that food eaten raw can be linked to virus transmission. It is important that customers and staff maintain good hygiene practices both near open food displays such as salad bars, fresh produce displays and bakery products, and during processing and serving. There is a higher risk of infection when buying apples and sandwiches than when consuming them. (WHO)

Lifetime of the virus on surfaces

Research has shown that under controlled laboratory conditions, SARS-CoV-2 can survive on stainless steel for up to 72 hours. (van Doremalen et al., 2020) The FDA recommends regular cleaning and disinfection of frequently touched surfaces such as work stations, cash registers, payment terminals, door handles, tables and worktops.

No viral replication in food

Corona viruses cannot multiply in food or on its packaging. They need an animal or human host in order to multiply. It is therefore not necessary to disinfect food packaging materials. But after handling packaging and before consumption, hands should be washed thoroughly. (WHO)
