Now calls are being made to dig two mass graves near a swimming lake and a water source due to contamination fears, according to the BBC.
It comes a day after thousands of corpses buried just three feet deep were pushed to the surface by gases released during the decomposition process.
This month’s slaughter was ordered without an environmental review; an oversight that was deemed illegal by the authorities, prompting the resignation of the country’s agriculture minister last week.
Opposition MPs say the slaughtered mink should be dug up and loaded into manure containers, which they say is a safer method of disposal.
Lawmaker Signe Munk told the BBC that buried mink was “an environmental time bomb” and said “the mink must be removed. ”
Prime Minister Mette Frederiksen burst into tears on Thursday as he visited a mink farm whose herd has been killed, ruining the family’s livelihood.
There are approximately 1,100 mink farms in Denmark, making it the largest producer of mink in the world.
