The United States Department of Agriculture announced it discovered a case of atypical bovine spongiform encephalopathy (BSE).
The five-year-old beef cow was discovered at a processing facility in South Carolina.
The animal came from a herd in Tennessee and showed signs of the disease upon arrival at the plant. The animal was then euthanized, Clemson University says.
Atypical BSE differs from classical BSE as it’s believed to occur spontaneously in cattle populations. Classical BSE occurs in cattle after ingesting prion contaminated feed.
