As we continue to navigate the COVID-19 pandemic, many questions arise about how the virus spreads and whether our food is safe to consume. Concerns about the potential of the coronavirus (SARS-CoV-2) surviving on food items have left consumers wondering if their grocery purchases can pose a health risk. In this comprehensive article, we will explore the scientific evidence surrounding the survival of COVID-19 on food, the implications for food safety, and the best practices for handling food during this unprecedented time.
Understanding COVID-19 Transmission
To comprehend how COVID-19 might be transmitted through food, we must first understand the primary modes of transmission. The main routes include:
- Person-to-person contact: Primarily through respiratory droplets released when an infected person coughs, sneezes, or talks.
- Surface contact: Infectious droplets can settle on surfaces, leading to potential transmission when people touch those surfaces and subsequently touch their face.
While food itself is not considered a primary mode of transmission, the concern lies in the possibility of the virus surviving on food packaging and surfaces for a certain period of time.
Can SARS-CoV-2 Survive on Food? Exploring the Evidence
Numerous studies have investigated the survival of SARS-CoV-2 on various surfaces and materials. Research indicates that the virus can survive on different surfaces for varying lengths of time. Here, we will summarize some key findings related to COVID-19 survival on food and food packaging.
Survival Duration on Different Surfaces
According to research published in the New England Journal of Medicine, the virus can remain viable on surfaces as follows:
| Surface Type | Survival Duration |
|---|---|
| Plastic | Up to 72 hours |
| Stainless Steel | Up to 48 hours |
| Copper | About 4 hours |
| Cardboard | Up to 24 hours |
When it comes to food, however, research suggests that SARS-CoV-2 does not survive for long periods on most food items.
Food Types and Virus Survival
Studies have shown that certain food types may present different risks when it comes to the survival of the virus:
Fruits and Vegetables: The virus’s viability on fruits and vegetables appears to be significantly lower than on non-porous surfaces. The moisture content and natural defense mechanisms of produce may inhibit virus survival.
Meat and Poultry: Laboratory studies indicate that the virus can survive on meats for a limited time; however, thorough cooking kills the virus, ensuring safety.
Processed and Packaged Foods: Packaging materials, such as cardboard and plastic, can harbor the virus. However, the food inside, when cooked, is unlikely to present any risk if handled properly.
Transmission Through Food: Real World Cases
Health authorities, including the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), have assessed the risk of foodborne transmission of COVID-19. They have concluded:
Low Risk of Transmission
The consensus from ongoing studies is that the risk of COVID-19 being transmitted through food is exceedingly low. The virus is primarily respiratory and not foodborne. Here are a few reasons why food transmission appears rare:
The conditions under which the virus must survive on food without infecting an intermediary host make it unlikely to spread through meals.
Most meals are prepared with heat that would effectively kill any viruses present.
Documented Cases of Food-Related Transmission
The reported instances of COVID-19 transmission through food are minimal. Some documented cases have involved food handlers who were infected, leading to potential contamination—highlighting the importance of personal hygiene in food preparation.
