Minks that were culled in Denmark over coronavirus concerns are beginning to rise out of their shallow graves, according to local news reports. Earlier this month, Prime Minister Mette Frederiksen said at least 12 people were infected with a mutated form of the coronavirus, originating at mink farms, prompting Denmark to order that more than 15 million minks be culled over fears that the strain would spread to humans. In a new development, some of the dead mink bodies have begun to come up out of the spots they were buried, creating a new public health concern. “As the bodies decay, gases can be formed,” a national police spokesman told a local news outlet. “This causes the whole thing to expand a little. In this way, in the worst cases, the mink get pushed out of the ground.” Overall, there are between 15 and 17 million minks on about 1,100 farms in Denmark. “It is very, very serious,” Frederiksen said earlier this month. “We have a great responsibility towards our own population, but with the mutation that has now been found, we have an even greater responsibility for the rest of the world as well.”
