Public Meetings on Brucellosis Regulations


Helena, Mont. – The Montana Department of Livestock (MDOL) will be holding a series of informational meetings on brucellosis regulations.  In October of 2018, requirements for brucellosis vaccination of female cattle and domestic bison were extended to Big Horn, Broadwater, Carbon, Jefferson, Stillwater, and Sweet Grass counties. Previously, brucellosis vaccination requirements only applied to the four counties in which Montana’s Designated Surveillance Area (DSA) is located (see image below).


A public meeting will be held in each of the 10 counties included in the brucellosis vaccination rule (ARM 32.3.436). The schedule is as follows:


  • Beaverhead County: September 10th 3-5:30 at the Beaverhead County Fairgrounds 4-H building in Dillon
  • Big Horn County: August 26th 8am-10:30 at the Big Horn County Courthouse in Hardin
  • Broadwater County: September 10th 8am-10:30 at the Broadwater County Fairgrounds 4-H building in Townsend
  • Carbon County: August 26th 1 pm-3:30 at the Carbon County Extension Office in Joliet
  • Gallatin County: September 9th 12 pm-2:30 at the Gallatin Conservation District in Manhattan
  • Jefferson County: August 28th 2:30 pm-5 at the Jefferson County Clerk and Recorders office in Boulder
  • Madison County: August 28th 8 am-10:30 at the Senior and Community Center in Twin Bridges

Dr. Eric Liska, Brucellosis Program Veterinarian for MDOL, will be discussing the expansion and enforcement of the vaccination rule along with general information about Montana’s DSA.

These informal meetings are intended to present new information as well as answer public and producer questions about brucellosis and brucellosis related regulations.
