LANSING, Mich. — Michigan has declared all but 11 of the 68 counties in the Lower Peninsula free of bovine tuberculosis.
The Department of Agriculture and Rural Development issued a map this month declaring 57 counties free of the disease. The remaining 11 are in the northern Lower Peninsula. They are Alpena, Alcona, Antrim, Charlevoix, Cheboygan, Crawford, Emmet, Montgomery, Oscoda, Otsego and Presque Isle.
Department Director Keith Creagh said in a statement "hard work by beef and dairy farmers" brought gains since Michigan first addressed the disease 17 years ago.
Bovine TB is a contagious bacterial disease of cattle and other animals. Authorities found it among Michigan deer in 1994.
Since testing began, 52 Michigan cattle farms have been affected by bovine TB.
