Meat Market Tenderized by China Tops a Big Week for Global Food

China has taken some unprecedented and unexpected steps to stir confusion and controversy when it comes to linking coronavirus outbreaks to food, acting against the advice of experts who say there’s little science backing the connection.

The country’s customs officials are asking global food exporters to sign a document that assures they’re meeting Covid-19 safety requirements to prevent transmission of the virus. This comes just after the Asian nation slapped a ban on poultry shipments from a plant owned by Tyson Foods after the company reported infections at the Arkansas site.
