The USDA has confirmed the discovery of classical scrapie in a sheep slaughtered in a facility in Oregon. (Oregon Department of Agriculture/Contributed)USDA’s Animal and Plant Health Inspection Service has confirmed classical scrapie in a sheep slaughtered in a facility in Oregon. The National Veterinary Services Laboratory will conduct tissue-matching and parentage testing on the affected sheep and two additional animals accompanying the affected sheep, according to an American Sheep Industry Association press release. The affected animal did not have an ear tag, which may limit traceability. “The importance of official scrapie tags cannot be understated,” stated Cindy Wolf, veterinarian and Animal Health Council co-chair for the sheep association.
