Officials have isolated a herd of pigs in Verdal, Nord-Trøndelag, after it tested positive for the H1N1 virus.
Knut Rønningen, the Norwegian Food Safety Authority’s (Mattilsynet) regional head of section, believes the disease has been in the pigs since the outbreak two years ago. He underlines there is no reason for public alarm, however.
“We find that the swine flu virus occurs fairly often and has become more common. 30 to 40 percent of herds we have studied since 2009 have been found to have the virus, but it can be carried by the animal without causing an outbreak,” he explained to Aftenposten.
Those most at risk of catching the virus are only people with direct access to the animals, like pig farmers. There is little chance others will catch the flu.
The pigs have been isolated for a week pending further tests by veterinarians.
