| Steel | Up to 48 hours |
| Copper | Up to 4 hours |
However, the risk of contracting COVID-19 from surfaces—known as fomite transmission—has been deemed low compared to direct person-to-person contact.
COVID-19 on Food: Research Insights
So, how long does COVID-19 survive on food itself? According to research, the survival of the virus on food is generally less concerning than on non-food surfaces. The primary transmission method remains respiratory, but it’s important to be informed.
Factors Influencing Virus Survival on Food
Several factors determine how long the virus can survive on food items:
- Type of Food: Certain foods may hold the virus longer than others due to their moisture content and surface texture.
- Environmental Conditions: Factors such as temperature, humidity, and pH levels can affect the virus’s longevity on food.
Type of Food
-
Fresh produce: Research has shown that viruses tend to survive longer on surfaces that are porous or not washed properly. However, fresh fruits and vegetables have a generally low risk of virus survival due to their high water content and often acidic pH.
-
Surface-treated items: Items like meats and dairy products may pose more risk if they are packaged inadequately. The virus can adhere to their surfaces when handled by an infected person.
Environmental Conditions
Studies indicate that the virus thrives in certain environmental conditions. Higher humidity and moderate temperatures can allow the virus to remain viable longer on food surfaces. For instance, in warmer temperatures, the viral load may diminish quicker than in cooler conditions.
Research Findings on COVID-19 and Food
A significant study conducted by the USDA looked into the survival time of SARS-CoV-2 on various food items:
-
Fruits and Vegetables: The virus was found to persist for up to 24 hours on items like apples and tomatoes, but they typically became less viable quickly when rinsed and handled properly.
-
Meats: On raw meat, especially processed poultry, the virus can stick around for approximately 2 to 7 hours.
-
Grains and Bread: The virus’s survival on dry goods is considerably low, often diminishing to undetectable levels within a few hours.
Practical Tips for Handling Food Safely
Given the findings, how can we protect ourselves regarding food safety during the pandemic? Here are essential guidelines:
Cleaning and Cooking
- Wash produce thoroughly with running water. This can help significantly reduce the presence of any residual virus.
- Cook foods at recommended temperatures. The heat effectively kills viral particles. For example, cooking meats to an internal temperature of at least 165°F (74°C) is critical.
General Hygiene Practices
- Always wash your hands with soap and water before and after handling food. If soap and water are not available, use a hand sanitizer containing at least 60% alcohol.
- Disinfect kitchen surfaces regularly, particularly if you frequently handle packaged goods or perishables.
Conclusion
In conclusion, while the risk of COVID-19 transmission through food is relatively low, it’s crucial to adhere to safety practices. The virus can survive on food surfaces for a limited time, and the best preventative measure is to maintain proper hygiene standards.
Handling food safely and cooking it adequately are your best defenses. By washing produce, cooking foods thoroughly, and adhering to general food safety practices, you can significantly mitigate risk, allowing you and your family to enjoy meals safely during this pandemic era. Always stay informed through trusted health resources to adapt to any new findings or guidelines related to COVID-19 as the situation evolves.
What is Long COVID and how does it relate to food safety?
Long COVID refers to a range of symptoms that persist for weeks or months after the initial infection of COVID-19. These symptoms can vary greatly among individuals and impact various bodily systems. As the understanding of the virus has evolved, concerns have emerged regarding how the virus might survive on various surfaces, including food. It’s important to clarify that Long COVID itself is not a virus that can be transmitted; rather, it refers to ongoing health issues resulting from the initial infection.
In relation to food safety, the key concern is primarily about the SARS-CoV-2 virus that causes COVID-19, not Long COVID itself. Studies indicate that the virus can survive on food surfaces for limited periods, which raises questions about the transmission of the virus through food consumption. However, the Centers for Disease Control and Prevention (CDC) and other health authorities have maintained that the risk of contracting COVID-19 from food is low, provided standard safety measures are taken.
How long can the SARS-CoV-2 virus survive on different types of food?
Research has shown that the SARS-CoV-2 virus can survive on various surfaces, including plastic, stainless steel, and cardboard, for several hours or days. When it comes to food, the survival time can differ depending on the type of food and the environmental conditions, such as temperature and humidity. Generally, studies suggest that the virus is less likely to survive on moist foods than on dry foods, with survival times typically ranging from minutes to a few hours.
However, it’s crucial to note that even if the virus were to be present on food, cooking it to the recommended temperature is effective in killing the virus. The CDC advises that proper cooking and handling of food remain the best strategies to avoid any potential transmission, with a particular focus on washing hands and surfaces regularly.
Should I wash my groceries to prevent Long COVID transmission?
Washing groceries has become a common practice for many as a precaution against COVID-19 transmission. While it is good practice to wash fruits and vegetables under running water, the CDC indicates that the risk of contracting COVID-19 from surfaces or packaging is low. Therefore, washing non-food items like plastic and cardboard packaging is not necessarily required. Instead, washing hands before and after handling food is of primary importance.
For certain foods, especially fresh produce, it’s advisable to rinse them thoroughly regardless of any potential virus present. High-risk individuals may choose to take extra precautions, but the general consensus among health experts is that focusing on cooking and safe food handling practices is far more effective in ensuring safety than excessively sanitizing groceries.
What precautions should I take when handling food during the pandemic?
When handling food during the pandemic, the primary prevention measures include practicing good hygiene and ensuring proper cooking techniques. Always wash your hands thoroughly with soap and water for at least 20 seconds before and after handling food.
