Saving the Danish Bacon?

The story about mutated coronaviruses on Danish mink farms gets more complicated (https://uk.reuters.com/article/uk-health-coronavirus-denmark-mink/denmark-has-found-214-people-infected-with-mink-related-coronavirus-state-serum-institute-idUKKBN27M11X?il=0). Although only 12 people, associated with 5 fur farms, were infected with a worrying variant, resulted in the decision to cull some 15 million animals, the Danish State Serum Institute reported that, since June, 214 people have been shown to harbour mink-related versions of coronavirus. Mink are mustellids and this Mammalian group seems very susceptible (like bats) to the virus. There are also wild mustellids, including ferrets and badgers who could carry the virus into the general environment. In the UK, there are even feral populations of mink that were released decades ago by animal rights protesters. Other Mammal species seem less susceptible, although the virus has been cultivated in laboratory mice (rodents) and found in domestic cats (felids). Hopefully, Denmark's numerous pig farms will not become repositories for sars-CoV-2 because mutations could occur here also. Neighbouring Finland also has mink farms but the virus has not been found in them, thus far. Having said that, a new variant of the Covid-19 virus could have profound medical consequences and the danger of the virus establishing itself in 'wild' and companion animal populations, in Europe, worrying.
