Brucellosis confirmed in Gallatin County herd, Montana Department of Livestock says
This is Montana's 15th confirmed brucellosis herd since 2010; early detection and removal of the infected pregnant animal helped limit spread and quarantine impact.
- Montana Department of Livestock confirmed earlier this year that an animal in a Gallatin County herd tested positive for brucellosis, the second detection this year.
- Montana's Designated Surveillance Area exists because of spillover risk from infected wildlife in the Greater Yellowstone Area, and since 2010 it has recorded 15 affected herds, including Beaverhead County earlier this year.
- Voluntary fall whole-herd testing flagged the infected animal, and officials removed the pregnant animal before calving to limit spread in the affected Gallatin County herd.
- Officials placed the herd under quarantine and launched an epidemiological investigation, with contact tracing underway and a three-year review period, MDOL said.
- Early detection and program testing aim to limit reproductive losses and reassure trading partners of Montana cattle operations, helping reduce movement requirements for Montana-origin and DSA-origin livestock, MDOL said.
