European pig farms are culled after the first confirmed African swine fever, or foot-and-mouth disease occurrence. Carcasses of wild pigs and boars are tested for these diseases too, and if they find an occurrence in the region, they will test every farm in that region. If you have a pig at your private farm, you are obliged to give some samples to a veterinarian for tests as well (and it's funded by the government). I would say that EU and Japanese veterinary norms are much stricter then US ones, but you still cannot import much of the food products from here.
