OIE: PRRS Outbreaks Reported in Swiss Farms07 December 2012
SWITZERLAND - The Swiss veterinary authorities have reported three outbreaks of porcine reproductive and respiratory syndrome (PRRS), also commonly known as blue ear disease, affecting piglet producer farms in Appenzell Innerrhoden and a breeding farm located in Hinterland.
The World Organisation for Animal Health (OIE) received an immediate report on Wednesday, 5 December 2012. The outbreak was initially observed on 28 November 2012 and confirmed on 29 November.
Upon examination, the outbreak has been identified as an asymptomatic (sub-clinical) infection, thereby putting the entire country's pig population at risk.
A total of 5099 pigs showed signs of susceptibility, out of which seven cases were reported. No deaths were recorded, and no animals were destroyed. Twenty six pigs were taken to slaughter.
Import of semen infected with PRRS virus has been identified as the cause of the outbreaks.
According to the OIE, all sows that received semen from boars from the German boar station were slaughtered. All sows positive in PCR received semen from infected boars.
Further, all other slaughtered sows that received semen from the boar station in the last two weeks were tested negative in PCR. Currently testing is continuing on all farms that received semen from the boar station and contact farms.
