Cold chain processing may help virus to survive
A cluster of COVID-19 cases in Dalian, Liaoning province, earlier this year was related to the cold chain in the seafood processing industry, Zhao Zuowei, director of the Dalian Health Commission, told a news conference in August.
Similar to new cases linked to the Xinfadi wholesale market in Beijing in June, the source of transmission in Dalian was tied to cold chain seafood products.
At the COVID-19 & Food Safety Global Summit on July 29, Chen Junshi, chief scientific adviser at the China National Center for Food Safety Risk Assessment, said media reports prompted consumer concern about buying, cooking and eating seafood, while positive test results from packaging of white shrimps from Ecuador added to people's concerns.
