Authorities say bovine tuberculosis has been found in a cow in a small beef herd in western Michigan's Lake County.
The Michigan Department of Agriculture and Rural Development said Wednesday that the infected, 3-year-old cow had been imported from an infected herd in Franklin County, Indiana, before that herd tested positive for bovine TB.
The agency says a three-mile surveillance area has been established around the affected farm in Lake County. Farms within the area will have six months to complete bovine TB testing.
Indiana last year found two beef herds and one white-tailed deer positive for bovine TB, all within Franklin County in that state's southeastern corner. Indiana and Michigan are among five states dealing with infected herds, along with New Mexico, South Dakota and Texas.
