Authorities from the Michigan Department of Agriculture and Rural Development say bovine tuberculosis has been found in a cow in West Michigan.

The three year old cow was in a small beef heard in Lake County and had been imported from an infected herd in Franklin County, Indiana.

The cow was euthanized.

The agency says a three-mile surveillance area has been established around the affected farm in Lake County and farms within the area will have six months to complete bovine TB testing.
