ALPENA, Mich. (AP) — Officials say a dairy cattle herd in the northeastern Lower Peninsula has tested positive for bovine tuberculosis.

The Michigan Department of Agriculture and Rural Development said Thursday the disease was found on an Alpena County farm with 50 to 100 cattle. The diagnosis was confirmed after routine testing by the state agency and the U.S. Department of Agriculture.

A public meeting to discuss the findings is planned for Jan. 10 at Wilson Township Hall.

Bovine TB is a contagious bacterial disease. All of Michigan's 14,000 cattle farms have been tested since an outbreak began in the mid-1990s. Bovine TB has been found on 55 of them.

Most of the state is designated as free of the disease, but 11 counties are considered at higher risk and require additional cattle testing.
