Seven Montana cows have tested positive for brucellosis, and if at least 2 cows from a separate herd near Emigrant test positive next week, Montana will lose its brucellosis-free status. That means Montana ranchers would have to pay to test all adult cattle being shipped out of state until Montana can regain its brucellosis-free status. The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is in charge of controlling the disease. APHIS rules say that a state loses its brucellosis-free status when at least two cows from two herds test positive within 12 months. On May 1, 51 Angus cows bound for Iowa were tested for brucellosis in Baker. Because Montana is a brucellosis-free state, the cows wouldn't normally be tested. But because the cows were going to be surrogate mothers, the tests were conducted.
On May 4, the Montana State Lab in Bozeman found that one cow tested positive for brucellosis. That cow was euthanized and tissue cultures were re-tested at the National Veterinary Services lab in Ames, Iowa, which conducts the testing for APHIS. The infected cow was traced back to a herd of 301 cows in Bridger, and that herd was quarantined after six more cows tested positive for brucellosis. Brucellosis is a contagious disease in ruminant animals that can cause fetuses to abort. The Bridger cattle came from a ranch near Emigrant, Schweitzer said. A second herd in the Paradise Valley is being tested now. To prevent the spread of brucellosis from bison to area cattle, officials from the Montana Department of Livestock have hazed wandering Yellowstone National Park bison back into the park. Last year, more than 1,000 bison that ranged onto private lands in Montana were captured, and most were sent to slaughter.
However, the governor said information he has received indicates that bison aren't to blame.)
