Can SARS-CoV-2 coronavirus be caught by eating?

Text updated on 2020-10-05


During a meal, the main risk of COVID-19 contamination is when interacting with others. Cooked foods, peeled and rinsed fruit/vegetables are not contaminants.

Transmission COVID-19 to the table. Epidemiological studies have shown that people have been infected after eating with their families or even just by eating out a few meters away from a table where there was an infectious person who was not coughing.

Cautionary measure. If food is cooked at high temperatures or boiled, the virus is inactivated and there is no risk. For fresh vegetables to be stored in the refrigerator, the general hygiene recommendation, even outside of the pandemic, is to wash them thoroughly with water and rinse them thoroughly before drying and storing them. Absolutely avoid bleach and all toxic detergents, which are extremely dangerous if swallowed!

Thoroughly wash your hands and all surfaces and utensils used for cooking. If someone has COVID-19 or has symptoms, it is best that they not to do the cooking. If you are cooking or handling food for people who do not live with you (for example, at work), wear a mask and clean gloves - use the gloves only when touching food!

In one restaurant, a pre-symptomatic COVID-19 person contaminated at least two other people more than 2 meters away, who were eating at two adjacent tables. Note that the space on the third floor of the restaurant was enclosed and ventilation must have contributed to the spread of the viral particles.
