EU calls for regular virus tests on mink farms
It also recommended "systematic genotyping" of detected strains and called for "the genome sequences from all infected animals (to be) shared."
Given the rapid spread among minks once the virus has been introduced, periodic testing of random samples should be done rather than farmers waiting until they see signs of the disease among the animals, it said.
The report was compiled by the European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC).
That includes 290 in Denmark, 69 in the Netherlands, 21 in Greece, 13 in Sweden, three in Spain, two in Lithuania and one in France and Italy each.
Denmark -- formerly the world's largest exporter of mink fur -- in early November ordered a mass cull of all of its more than 15 million minks after a mutated version of the virus was discovered and believed to jeopardise the effectiveness of future vaccines.
