Unsuccessful associations before the courts

The Ministry of Agriculture announced Wednesday to slaughter "more than 10,000 mink" of farms where cases of new coronavirus have been found, to prevent them from becoming sources of contamination. Two animal rights groups seized Dutch court on Thursday to try to prevent the measure, but their request was dismissed Friday evening.

The slaughter of animals therefore "started today (Saturday) in a mink farm in Deurne" in the south of the Netherlands, said Frederique Hermie, a spokesperson for the security agency. food and health (NVWA). "This company has about 1,500 females, each of which has four to five pups," Hermie told AFP, adding that the animals are killed using carbon monoxide. The mink slaughter in the nine other contaminated farms will continue during the week, she said.

Farms closed by 2024
