CoV infection mostly occurs during winter and spring in temperate countries; the virus has high transmission efficiency and may have severe infection outcomes. The recent SARS-CoV-2 outbreak exhibited transboundary transmission due to international transportation, trade, and economic exchange. Animal hosts provide a persistent source for CoVs and their recombination. Domestic camels have been shown to be one of the hosts of CoVs, while livestock, poultry and other warm-blooded animals may act as intermediate hosts for CoVs. This paper outlines the biological and epidemiological characteristics and diagnosis of CoVs and describes the origin, transmission route, animal-source food risk, and control measures for CoVs. Such knowledge can be used to prevent CoVs from harming consumers through animal-sourced foods and can help to prevent new zoonoses from occurring. This work will provide a reference for strengthening the controls on the production process in meat production companies, thereby improving food safety.Keywords: coronavirus, meat, food safety, prevention and control
