Pig production and health status of pigs in Sweden
The Swedish sow populations comprise 140.000 sows and around 3 million pigs are annually reared to market weight. During 2014 there were nearly 1,300 production herds.
The health status of the Swedish pig population is favourable due to the geographic location at the Scandinavian Peninsula and due to a restricted import of live pigs. Import restrictions used to be administered by the Swedish Board of Agriculture, but since Sweden joined of the EU that mission has been overtaken by a branch organisation entitled the Swedish Farmers Disease Control.
Pigs in Sweden are declared free from all infections presented on the A-list of the International Office of Epizootics (OIE) as well as from porcine epidemic diarrhea (PED), porcine reproductive and respiratory syndrome (PRRS) and transmissible gastro-enteritis (TGE). Aujeszky´s disease (AD) was eradicated in 1997. A national control program combat Salmonella whenever diagnosed - regardless of serotype. Since 1984, Salmonella has in general been diagnosed in less than 5 pig herds per year.
Nucleus and multiplying herds are also declared free from Atrophic rhinitis (toxin producing strains of Pasteurella multocida), Brachyspira hyodysenteriae and Sarcoptes scabieii. This is documented annually by laboratory tests.
