LANSING, MICHIGAN — Today, State Veterinarian Nora Wineland, DVM, released the following statement due to the designation of a bovine tuberculosis positive herd in Alcona County.

“Bovine TB was recently confirmed in a medium sized beef herd in Alcona County, which is in Michigan’s Modified Accredited Zone. The animals were confirmed positive for bovine TB by the National Veterinary Services Laboratories on January 13, 2020. As in all new findings of infected cattle herds, additional testing will be done to identify the specific bacterial strain, and trace testing will begin in order to identify any potential additional cases associated with the affected herd.

Bovine TB is a bacterial disease that can affect all mammals, including humans. It is present in the free-ranging white-tailed deer population in a specific area of northeastern lower Michigan and can be transmitted from the deer into cattle herds. Michigan has been working to eradicate bovine TB in cattle since 1998 when a cattle herd was found positive in Alpena County. The Alcona County herd is Michigan’s 77th cattle herd to be identified with bovine TB.
