Alberta Pork announced a third and fourth case of porcine epidemic diarrhea (PED) virus had been discovered at separate hog operations in Alberta last week. On Monday, they clarified that the third case was a false positive.
“The investigative laboratory identified the virus in a sample, but pigs at the formerly-suspected affected premise have shown no signs of illness,” Alberta Pork states. “False positives are infrequent but can be expected occasionally in disease investigations, due to the sensitivity and concern for positive results.”
As of now, there have been three confirmed outbreaks of PED in Alberta in 2019. Alberta Pork is working closely with Alberta Agriculture and Forestry to investigate the most recent outbreak and prevent the disease from continuing to spread.
“Any place off-farm, such as an abattoir, should be considered as a potential source for bringing disease to your herd,” says an Alberta Pork statement. “Producers are reminded to review their farms’ biosecurity policies regularly and consult Alberta Pork or your herd veterinarian as required.”
According to the Calgary Herald, regular operations have resumed at the site of the first outbreak after a veterinarian’s inspection.
