The above is of course true, but my question was rather if it was sufficient? After all, trials have shown that the virus can be transmitted via air and at least mink have been infected after being reintroduced to a farm which was disinfected and left out of use for two years. I saw the numbers of how many of the tested ones came out positive, but I don't know enough to relate that to how many ferrets out of all were tested. If one ferret develops symptoms, and one then tests those who live with and has had contact with it, it's to be expected a large proportion will be positive. (Unfortunately, because there's no rabies in the UK, it's relatively easy to import ferrets from there to Sweden, and AD testing isn't required, so I've been a bit worried about a possible introduction here for years.) -- Urban Fredriksson [log in to unmask] http://www.canit.se/%7Egriffon/ferrets/ [Posted in FML issue 2748]
