The pseudorabies (PRV) virus has been diagnosed on a game ranch in Saginaw County, MI, according to the Michigan Department of Agriculture (MDA).

The virus was detected as a result of laboratory testing. No clinical signs have been detected. No commercial facilities were known to have been exposed to the virus and depopulation of the game herd is underway.

Feral swine adjacent to the game ranch have also been confirmed positive for PRV. As a result of these findings, the MDA has instituted circle testing of swine within a five-mile radius of the outbreak.

MDA encourages Michigan residents to shoot feral swine and to have MDA test the carcass for disease.

Michigan is expected to retain its PRV-free status as long as commercial operations remain free of the virus.
