　　All foods, including seafood, will not be infected with the new coronavirus, but there may be the possibility of being contaminated by the new coronavirus. At present, it cannot be ruled out that low-temperature refrigerated foods and food packaging materials are used as virus carriers, causing the new coronavirus to pollute the environment and cause the possibility of human transmission. At present, my country's customs has to sample every batch of imported food and conduct new coronavirus testing. In order to prevent foods contaminated by new coronavirus from entering the food chain, it is very important to increase the supervision of all links, strengthen the main responsibility of food companies, and strengthen consumers' self-protection awareness.
