Poland, which is a major producer of mink fur, started coronavirus tests among its farmed minks and checks among the workers earlier this month after a mutated virus was detected in farmed minks in Denmark, leading to a nationwide cull there.

18 cases of corona found among farm workers. Sanitary department believe that they were not infected from animals. While the authorities have not yet received results of the animal tests, it said that COVID-19 cases were confirmed among people connected with the farms. Poland is one of the world’s top producers of mink fur, with 354 farms, containing around 6 million minks.
