A pig head imported from North America was confirmed as the source of the recent COVID-19 outbreak in Tianjin, said Zhang Ying, deputy head of the Tianjin Centers for Disease Control and Prevention.
What is the cause of Hailian Cold Storage? Zhang Ying analyzed that on November 7th, we received a notification from Dezhou City, Shandong Province that a batch of imported pork knuckles transferred from Tianjin Port to them tested positive for nucleic acid in the outer packaging. Then, according to this line, Tianjin The Health Commission conducted a full investigation on the Hailian Cold Storage and found Case No. 138 and Case No. 139.
Case 138 is a mover, and the unloaded goods are pork knuckles from Germany.
Case 139 was the driver who transported the goods. He transported North American pig heads, but he had never transported German pork knuckle.
According to the current research, the two did not know each other, and there was no intersection. In addition, the pork knuckles are stored in cold storage No. 4, and the pig heads are transported away at gate 6. There is no intersection between the two items.
Further epidemiological investigations were carried out and the monitoring in the cold storage was called, and finally the main reason for the infection of Case 139 was identified."According to the current epidemic situation, the alert in the medium-risk regions, Hangu Street, Block A and B of the cold-chain logistics area in the central fishing port in Binhai New Area, will be downgraded to low risk beginning Wednesday," said Gu Qing, deputy director of the city's health commission.
