On Wednesday, the Michigan Department of Agriculture and Rural Development announced in a press release that it had detected bovine tuberculosis in cattle in Alcona County during the herd’s regular testing.

The detection is the 83rd in Michigan among cattle since 1998, the press release says.

Bovine TB is a bacterial disease that can affect all mammals, including humans. It is known to be present in the free-ranging white-tailed deer population in specific areas of northeastern lower Michigan, and the disease can be transmitted between deer and cattle. As a result, there are currently two TB zones within the state: a four-county area in northern lower Michigan called the Modified Accredited Zone and the remainder of the state is referred to as the Accredited Free Zone.
