Brucellosis/Montana's Designated Surveillance Area (DSA)
Some variances may be available with a herd plan (call MDOL at 406-444-2043).
Brucellosis (Bangs) Vaccination:
Within the entirety of counties in which the DSA is located (Beaverhead, Gallatin, Madison and Park), all sexually intact female cattle and domestic bison that are four months of age or older as of January 1 of any year must be Official Vaccinates.
Brucellosis Testing (Bleeding):
Sexually intact and 12 months of age or older
Any age intended to be used for breeding purposes
No test is required to take animals to an approved Montana livestock market that will test on arrival.
A test completed July 16 or after is acceptable for movement out of the DSA or change of ownership through February 15 the following year.
Identification and Disease Traceability:
All sexually intact cattle and domestic bison (regardless of age) leaving the DSA must be officially identified.
Official individual identification tags include:
- Electronic Identification Device (EID) tags (also known as RFID tags);
- Orange brucellosis (metal or RFID) vaccination tags on officially brucellosis vaccinated females;
- Silver metal "Brite" tags (available to producers at no charge from the MDOL or USDA-APHIS office);
- Some "age-source" program tags qualify as individual identification.
Current DSA Boundaries
