Q - Is it true that some viruses are resistant to heat and cold? If so, what food safety precautions should customers take?
A -Foodborne viruses are not especially resistant to heat. Most virus outbreaks are the result of foods that are not cooked, or are contaminated after cooking. A lot of viruses are very stable in the environment, but cooking is good at denaturing the proteins that protect the virus. that is it is important to cook food, including seafood, thoroughly before eating it.
In other words,, it is true that viruses are resistant to cold. Chilling or freezing does not eliminate viruses. Good agricultural and manufacturing practices along the farm-to-table continuum are needed to keep food from being contaminated by pathogens in the first place.
