Saginaw herd tests
positive for Tuberculosis
A herd of cows in Saginaw County has tested positive for bovine tuberculosis.
Michigan's Department of Agriculture and Rural Development announced the laboratory results. The entire herd was tested after one of the dairy cows tested positive for the Michigan strain of tuberculosis during slaughter surveillance.
The state will test a 10-mile circle around the farm to see if other herds have been infected. MDARD Bovine TB Program Coordinator Rick Smith says there are 66 farms in the 10-mile area around the herd.
Bovine tuberculosis is an infectious disease caused by bacteria. The state says it usually affects only cattle, but can be spread to other animals. Bovine tuberculosis impacts the lungs and potentially other intestines.
