As a top food website, FOODS.EDU.VN understands the importance of food safety, especially concerning viruses like COVID-19. The COVID-19 virus can survive on various food items and packaging for different durations. While the risk to consumers remains low, understanding how long the virus persists on different food surfaces can help you take informed precautions.
1. Understanding COVID-19 and Food Contamination
1.1. How Does COVID-19 Spread to Food?
COVID-19 primarily spreads through respiratory droplets produced when an infected person coughs, sneezes, talks, or breathes. While less common, it’s possible for these droplets to land on food or food packaging, potentially contaminating them.
1.2. Is Food a Significant Transmission Route for COVID-19?
According to organizations like the Centers for Disease Control and Prevention (CDC) and the Food Standards Agency (FSA) in the UK, food is not considered a primary route of transmission for COVID-19. The main mode of transmission remains close person-to-person contact. However, understanding the potential for surface contamination can help minimize risks.
1.3. What Does “Viable Virus” Mean?
When discussing how long COVID-19 can live on food, it’s important to understand what “viable virus” means. A viable virus is one that is still capable of infecting a person. Studies often measure the presence of the virus’s genetic material (RNA), but the presence of RNA doesn’t necessarily mean the virus is still infectious.
2. Research Findings on COVID-19 Survival on Food Surfaces
2.1. Overview of Key Studies
Several studies have investigated the survival of COVID-19 on various surfaces, including food and food packaging. These studies typically involve inoculating surfaces with the virus and then measuring the decline in viral load over time. It’s important to note that these studies often use higher concentrations of the virus than would typically be found in real-world scenarios.
2.2. FSA Study on Food and Packaging
The UK’s Food Standards Agency (FSA) conducted research that specifically looked at the survival of COVID-19 on food and packaging. The study involved intentionally contaminating various food items and packaging materials with the virus.
The FSA study is noteworthy because it examined a range of food items and packaging materials, providing insights into the varying survival rates of the virus.
2.3. University of Southampton Findings
Scientists at the University of Southampton were involved in the FSA study, and their findings indicated that while the virus levels significantly dropped within the first 24 hours on most food products, traces could survive for about a week in some cases.
The University of Southampton’s findings highlight the need for awareness, even though the risk to consumers is considered low.
3. How Long Does COVID-19 Last on Different Types of Food?
3.1. Fresh Fruits and Vegetables
The survival of COVID-19 on fresh produce varies depending on the surface characteristics.
3.1.1. Smooth-Skinned Fruits and Vegetables
On smooth-skinned fruits like apples, the virus tends to disappear more quickly. According to the FSA study, natural chemicals in the skin of apples may contribute to breaking down the virus.
3.1.2. Uneven-Surfaced Fruits and Vegetables
Produce with uneven surfaces, such as broccoli and raspberries, may harbor the virus for a longer period. The nooks and crannies on these surfaces can provide a more conducive environment for the virus to persist.
| Food Item | Survival Time |
|---|---|
| Apples | Minutes to hours |
| Broccoli | Up to a week |
| Raspberries | Up to a week |
| Chilled Peppers | Detectable after a week |
3.2. Baked Goods
3.2.1. Pastries
Pastries like pain au chocolat may have reduced viral presence after a few hours. The FSA scientists suggested that this could be due to the egg wash applied during baking, as eggs contain arachidonic acid, which might have an antiviral effect.
3.3. Deli Items
3.3.1. Cheese and Cold Meats
Deli items such as cheese and cold meats, which have high protein and fat content, appear to allow the virus to survive for days, possibly up to a week.
3.4. Drinks and Ready Meal Containers
3.4.1. Plastic Surfaces
COVID-19 can survive for up to a week on plastic surfaces, making plastic drink bottles and ready meal containers potential carriers of the virus.
3.4.2. Cartons
On cartons, the virus may survive for several days.
3.4.3. Aluminum Cans
Aluminum cans appear to have a shorter survival time for the virus, likely only hours.
| Packaging Material | Survival Time |
|---|---|
| Plastic | Up to a week |
| Cartons | Several days |
| Aluminum Cans | Hours |
3.5. Comparison Table of Food Types and Viral Survival
| Food Type | Examples | Estimated Survival Time |
|---|---|---|
| Smooth-Skinned Fruit | Apples | Minutes to hours |
| Uneven Fruits/Veg | Broccoli, Raspberries | Up to a week |
| Pastries | Pain au chocolat | Few hours |
| Deli Items | Cheese, Cold Meats | Up to a week |
| Plastic Containers | Drink bottles, Ready Meals | Up to a week |
| Cartons | Juice boxes | Several days |
| Aluminum Cans | Soda cans | Hours |
4. Factors Influencing Virus Survival on Food
4.1. Temperature
Temperature plays a significant role in how long COVID-19 can survive on food. Lower temperatures generally allow the virus to survive longer.
4.2. Humidity
Humidity levels also affect viral survival. Higher humidity can sometimes prolong the survival of the virus on surfaces.
4.3. Surface Type
The type of surface, whether it’s smooth or porous, can influence how long the virus remains viable. Porous surfaces may trap the virus, potentially prolonging its survival.
4.4. Viral Load
The initial amount of virus present (viral load) significantly impacts how long it can be detected. Higher initial loads mean it takes longer for the virus to degrade to undetectable levels.
4.5. Food Composition
The composition of the food itself can influence viral survival. For instance, foods with high protein and fat content, like cheese and cold meats, may allow the virus to survive longer.
5. Practical Steps to Minimize Risk
5.1. General Food Safety Practices
Following general food safety practices is crucial to minimize the risk of any foodborne illness, including potential COVID-19 contamination.
5.1.1. Hand Washing
Wash your hands thoroughly with soap and water for at least 20 seconds before and after handling food, especially before eating. This is one of the most effective ways to prevent the spread of viruses and bacteria.
5.1.2. Rinsing Produce
Rinse fresh produce under running water to help remove any surface contamination. While soap and detergents are not recommended for washing produce, a thorough rinse can be effective.
5.1.3. Cleaning and Disinfecting Surfaces
Regularly clean and disinfect kitchen surfaces, including countertops, cutting boards, and utensils. Use appropriate cleaning agents and disinfectants to kill any potential viruses or bacteria.
5.2. Specific Precautions for COVID-19
While the risk of contracting COVID-19 from food is low, taking a few extra precautions can further minimize any potential risk.
5.2.1. Washing Hands After Grocery Shopping
