Consumers in the Chinese city of Shenzhen have been urged to exercise caution when buying imported frozen food after a surface sample of chicken wings from Brazil tested positive for coronavirus, according to a statement from the local government.
The positive sample appears to have been taken from the surface of the meat, while previously reported positive cases from other Chinese cities have been from the surface of packaging on imported frozen seafood.
The chicken came from an Aurora Alimentos plant in the southern state of Santa Catarina, according to a registration number given in the statement.
Three packaging samples of imported frozen seafood tested positive for Covid-19 in Yantai, a northern city of China's Shandong province, the city government said on its official Weibo account on Tuesday. State television on Wednesday reported that the outside of an Ecuador frozen shrimp package tested positive for the virus in a restaurant in Wuhu, a city in China's Anhui province.
