Designated Surveillance Area (DSA)


The DSA is an area of Idaho where brucellosis positive wildlife are known or believed to exist and where comingling of wildlife and livestock may lead to transmission of brucellosis from wildlife to livestock. Please see the DSA map* for the borderlines and a description of the DSA boundaries.

Any cattle and domestic bison leaving the DSA must meet the following requirements:

          - Individual official identification; acceptable forms of ID are:
                         - Orange brucellosis vaccination tag
                         - Silver USDA tag
                         - RFID tag

          - Negative brucellosis test for test eligible animals within 30 days before
            leaving the DSA if the cattle have been in the DSA anytime between
            January 1 and June 15 of any calendar year. Exceptions to testing are
            provided for animals going directly to an Idaho Approved Livestock Market
            or a USDA-inspected slaughter facility located in Idaho.
