You Probably Won't Catch the Coronavirus From Frozen Food

Amid a flurry of concern over reports that frozen chicken wings imported to China from Brazil had tested positive for the coronavirus, experts said on Thursday that the likelihood of catching the virus from food -- especially frozen, packaged food -- is exceedingly low. From a report: "This means somebody probably handled those chicken wings who might have had the virus," said Angela Rasmussen, a virologist at Columbia University. "But it doesn't mean, 'Oh my god, nobody buy any chicken wings because they're contaminated.'" Guidelines from the Centers for Disease Control and Prevention maintain that "there is no evidence to suggest that handling food or consuming food is associated with Covid-19." The main route the virus is known to take from person to person is through spray from sneezing, coughing, speaking or even breathing. "I make no connection between this and any fear that this is the cause of any long-distance transmission events," said C. Brandon Ogbunu, a disease ecologist at Yale University. When the virus crosses international boundaries, it's almost certainly chauffeured by people, rather than the commercial products they ship. The chicken wings were screened on Wednesday in Shenzhen's Longgang district, where officials have been testing imports for the presence of coronavirus genetic material, or RNA. Several samples taken from the outer packaging of frozen seafood, some of which had been shipped in from Ecuador, recently tested positive for virus RNA in China's Anhui, Shaanxi and Shandong provinces as well. Laboratory procedures that search for RNA also form the basis of most of the coronavirus tests performed in people. But RNA is only a proxy for the presence of the virus, which can leave behind bits of its genetic material even after it has been destroyed, Dr. Ogbunu said. "This is just detecting the signature that the virus has been there at some point," he said.
