Denmark is digging up mass graves containing the bodies of millions of dead mink after a report from the country’s environmental agency warned that they could contaminate local groundwater. 

Last year, Danish officials reported that minks were infecting humans with a mutated COVID-19 strain, leading to harsh containment measures and the eventual decision to cull Denmark’s entire 17 million mink population in November of 2020. Denmark has one of the largest mink industries in the world, with the country exporting the mammal’s fur to high-fashion companies and coat manufacturers.
