What is the status of brucellosis in Montana?
From 1985 until May 17, 2007, there were no cases of brucellosis detected in Montana’s livestock. On May 18, 2007, brucellosis was detected in one Montana cattle herd (Carbon County). Subsequently, on June 9, 2008, brucellosis was detected in a second Montana cattle herd (Park County). This herd was tested as part of Montana’s efforts to test and develop brucellosis risk mitigation herd plans for herds near the Greater Yellowstone Area. [Top] On September 3, 2008, because of these two infected herds within a two-year period, USDA officially downgraded Montana’s brucellosis status from Class Free to Class A. The Department of Livestock has been working on a brucellosis action plan, and will reapply for Class free status as soon as possible after May 27, 2009.

The Department of Livestock (MDOL) responded by developing and implementing the Brucellosis Action Plan (BAP) in May 2009.
