The findings came in the form of the Chinese Center for Disease Control and Prevention (CDC), which detected live coronoviruses on the outer packaging of frozen cod during an outbreak reported virus attempt last week in the city of Qingdao Was. Website.
A discovery, for the first time, suggests that it is possible for the virus to be transported long distances via frozen cargo.
Officials said two dock workers in Qingdao were initially identified as having asymptomatic infections, which brought the virus to the hospital of the chest during quarantine due to insufficient disinfection and safety, leading to another 12 hospital-associated infections .

However, the CDC’s latest statement does not provide solid evidence that two workers in QingDao caught the virus directly from the packaging, rather than contracting the virus elsewhere and then contaminating the food packaging they controlled, Jin Dong -Yan, a virology professor at the University of Hong Kong.
The CDC stated that no consumer has found any instance of exposure to the virus due to exposure to frozen food and the risk of this happening is very low.
Nevertheless, it was advised that workers handling, processing and selling frozen products should avoid direct skin contact with products that could possibly be contaminated.
Employees said employees should not touch their mouths or noses before taking off work clothes, which could possibly be contaminated without washing their hands and should be tested regularly, the agency said.
Prior to the CDC’s latest findings, genetic traces of the virus were found in some samples taken from frozen food or food packaging, but the amount of virus was small and no live virus was isolated, the agency said.
Only living viruses can infect people, while samples with dead viruses can also test positive for traces of the virus, Jin said.
