Health authorities in the City of Fuyu said authorities in China’s northeastern Jilin province have found the novel coronavirus on the packaging of imported squid and urged anyone who may have bought it to get themselves tested.

Fuyu city’s health office said on its official WeChat account on Sunday said one of the packages had arrived in the city via the provincial capital Changchun.

It asked people who had bought and eaten imported squid at the local Sanjia Deda frozen seafood wholesale shop from Aug 24 to Aug 31 to report to neighborhood authorities and seek a COVID-19 test.

The Changchun COVID-19 prevention office said the squid had been imported from Russia by a company in Hunchun city and brought to the provincial capital.

Chinese customs said on Friday they would suspend imports from companies for a week if frozen food products tested positive for coronavirus and for a month if a supplier’s products tested positive for a third time or more.
