Officials say bovine tuberculosis has been detected in a western Michigan cattle herd.
The state Department of Agriculture and Rural Development says two cattle that tested positive at a processing facility were traced to a farm in Ottawa County.
The department has established a three-mile surveillance area around the farm. All cattle in the area must undergo testing within six months.
Officials say the infected animals originated with a herd in Franklin County, Indiana, that tested positive for bovine TB in 2016.
The TB strain involved is not the one that’s been detected in deer.
