Laramie, WY – Tests on about 3,000 Montana cattle have
turned up no additional cases of the livestock disease brucellosis, that showed up last May in a herd near Bridger.
Montana livestock officials say some testing will continue; but they say the results announced today offer strong evidence that the brucellosis was limited to a single herd.
Montana cannot have any additional cases of brucellosis for at least two years after the initial infection, or it could lose its federal disease-free status.
That would force ranchers to undergo a costly vaccination program, and possibly damage the reputation of Montana's cattle
Brucellosis causes pregnant cows to abort their calves. It has been wiped out across most of the country; but persists in bison, elk and other wildlife around Yellowstone National Park.
