I too was surprised that “enlightened” countries
like Denmark and the Netherlands were involved in industrial scale fur farms.
I wondered where the market for such product could be as fur is definitely out of favour for fashion clothing in these days .
No surprises ! China is the main recipient of farmed animal pelts. It would seem the mink are the ones with a grievance as they were infected by farm workers, they recovered and passed the virus back in mutated form.
Time to learn that keeping animals in a crowded , hot house environment is unhealthy for all concerned
