Decomposing mink buried in dirt pits in Denmark following a nationwide cull may have contaminated groundwater, local Radio4 reported on Thursday, citing a government agency report. The Danish government ordered a cull of some 17 million mink in early November after outbreaks of coronavirus hit hundreds of farms and authorities found mutated strains of the virus among people. The logistical challenge of disposing of such a large number of dead animals prompted authorities to bury some of the mink in pits in a military area in western Denmark under two metres of soil.
