Montana Proposes Expanding Brucellosis Surveillance Area Near Dillon
Montanans may submit public comment on a proposal to expand the Designated Surveillance Area for brucellosis in the southwest part of the state. If approved, the DSA would expand to include the area between Dillon, Twin Bridges and Alder.
The Montana Department of Livestock says a brucellosis-infected cow from a Madison County ranch was identified during a voluntary whole-herd test. The animal was euthanized, and the infection confirmed at the National Veterinary Services Laboratories in Iowa. The cow tested negative last year.
