Disease control and prevention workers collect samples from frozen products in Tianjin's Nankai district on November 9, 2020. Zhong's comments came amid outbreaks in Chinese cities that were caused by contaminated outer packaging of imported cold-chain foods. "Can humans get infected by the outer packaging of frozen products? These new problems require us to discover the transmission patterns and come up with preventive measures," Zhong pointed out at an event Saturday. Earlier, the Chinese Center for Disease Control and Prevention (CDC) had detected and isolated living coronavirus in a positive sample from the outer packaging of imported frozen cod in Qingdao, in eastern Shandong province.
