The Minnesota Board of Animal Health announced Tuesday that investigators have found bovine tuberculosis in a seventh herd in Minnesota.

The case was found in one cow in Beltrami County, which is, with Roseau County, one of only two counties in northwestern Minnesota in which the disease has been discovered.

According to the Board of Animal Health, the herd is small and has had minimal movement, boding well for the containment of this case. Minnesota will not be able to apply for TB free accreditation until two years after the elimination of its last infected herd.

Although each new herd discovery pushes that period back, Minnesota state veterinarian Dr. Bill Hartmann says the Board of Animal Health will remain diligent in its tests and efforts to eradicate the disease. "Finding another positive herd will reset our timeline for regaining status, but for the sake of Minnesota's cattle industry, we cannot leave a single infected herd undiscovered," he says.

The Minnesota Department of Natural Resources will contribute to the board's efforts by collecting a planned 5,000 samples from white-tail deer killed by hunters this fall. Two deer have tested positive for bovine TB within a mile of the infected cattle herd this past year.
