MOVEMENT TRACKING: Movement investigations from the bovine TB-positive herd identified in January in Alcona County led to the finding of two additional infected herds.

2 Michigan cattle herds test positive for bovine TB

Infected animals found in Allegan and Saginaw counties.

Two newly identified bovine tuberculosis-infected cattle herds recently were announced by state veterinarian Nora Wineland.

"Movement investigations from the bovine TB-positive herd identified in January 2020 in Alcona County led to the finding of two additional infected herds,” Wineland says. “One herd is in Allegan County and will be Michigan’s 78th infected herd identified since 1998. The other is a feedlot in Saginaw County, which is the sixth infected feedlot in the same time frame. Prior to finding infection in the Alcona County herd, animals were moved into these two herds.”

When an infected herd is found, an investigation into the location of potentially exposed animals is routinely done, Wineland explains. It was through that investigation that the newly infected herds were found.

“The ability to quickly identify and track movements of animals out of infected herds is an important tool to prevent further spread of disease,” she adds. “Cattle surveillance will be carried out around the infected herds. Cattle producers in the surveillance area will be contacted directly.”

The Allegan County herd was confirmed positive March 10, and the Saginaw County feedlot was confirmed positive March 16 by the National Veterinary Services Laboratories.

Bovine TB is a bacterial disease primarily affecting cattle. However, it can be spread between wildlife populations and other mammals, including humans. Michigan has been working to eradicate bovine TB since 1994 when a hunter-harvested whitetail deer tested positive in Alpena County.
