China Targets Frozen Food Imports Over Virus Fears

Chinese health officials said Wednesday that two cold-chain storage workers in the port city of Tianjin were infected with Covid-19, as the country shifts focus to contaminated imports after a number of outbreaks linked to frozen food.

Workers in hazmat suits were painstakingly screening food shipments across a country which has largely brought domestic infections under control but now blames a resurgence of local infections on imports.

Mass-testing campaigns have been rolled out after reports of coronavirus traces on imported food and packaging, with state TV showing workers hosing down food transport trucks with disinfectant and inspecting packages of frozen salmon.

Two cities in southern Fujian province said Wednesday they found traces of the virus in shipments of pomfret from India and beef from Argentina.

In Wuhan, where Covid-19 first emerged in late 2019, authorities said last week they had detected the virus on frozen beef from Brazil, while several other cities reported positive test results on samples from imported food -- including Argentinian pork and Indian cuttlefish.

Customs inspectors across the country have so far tested more than 800,000 samples from refrigerated imports and suspended shipments from 99 overseas suppliers, customs official Bi Kexin told a press conference last week.

Authorities have stepped up screening since coronavirus traces were found on equipment used to process imported salmon after a June outbreak.

In Tianjin, officials said the two infected workers "had previously both had contact with contaminated cold-chain food products".

Customs data in September showed that Chinese meat imports had increased by more than 70 percent this year as the country's food supply was disrupted by swine fever and heavy flooding which destroyed swathes of farmland.

The World Health Organization says "there is currently no evidence that people can catch COVID-19 from food or food packaging".

Transmission of Covid-19 across countries on frozen food is "possible but it has not been comprehensively studied so we do not know the extent of this spread", Paul Tambyah, president of the Asia Pacific Society of Clinical Microbiology and Infection, told AFP.

China's foreign ministry defended the measures on Wednesday as "very reasonable and legitimate".

Screening has been ramped up after the outbreak in Tianjin -- just over 70 miles (110 kilometres) from the capital Beijing -- was linked to food transport workers, sparking fears of a second wave of virus cases in the coming winter.

Earlier this month, China banned visitors from countries including the UK and India and raised testing requirements for other travellers.

State media has also ramped up claims that imported food could have been to blame for the initial Wuhan outbreak, where the virus was first linked to a seafood market.

Beijing insists that the source of the initial outbreak remains a mystery and that it may not have originated in China -- a claim vigorously disputed by countries including the US and Australia.

The foreign ministry also floated a conspiracy theory earlier this year that the American military may have brought the virus to Wuhan last year.
