It is not impossible for chilled seafood products to carry viruses on the surface or outer packaging

Jiang Qingwu, an epidemiologist and former dean of the School of Public Health of Fudan University, said that if seafood products are contaminated with new coronavirus in the external environment during chilled packaging, loading, unloading and transportation, they will grow in a cold environment. Survival in time is likely to spread from a long distance; in the cutting and distribution process after reaching the destination, it is not impossible to spread the virus to the external environment or even infect people.
