For the first time in around 50 years, bovine tuberculosis has been detected in a cattle herd in Montana.

The Montana Department of Livestock says meat inspectors at a plant in Minnesota detected the infected cow and traced it back to a herd in Blaine County. That herd is now under quarantine.

State Veterinarian Marty Zaluski says three cows that are part of the Blaine herd have tested positive for bovine tuberculosis so far and an investigation will “determine if other herds or wildlife are involved.”

Bovine tuberculosis can infect other wildlife, including deer, as well as humans through the consumption of raw milk.
