Officials determined last month that all of the country’s more than 15 million mink would need to be slaughtered, after a mutated version of COVID-19 — with the potential to weaken the effectiveness of vaccines — was discovered in fur farms and factories. 

Authorities, who could not handle incinerating so many dead animals at once, instead buried many of them just three feet deep in a military training field in West Jutland, The Guardian reported. 

Some have even risen from their graves like zombies, propelled by gases released during the decomposition process.

As a result of the mass burials, groundwater in the area may have already been polluted by the carcasses of the furry critters, local station Radio4 reported, citing a study for the environmental protection agency.
