If one shows up positive or suspect, all animals in the herd are tested.
Tests have confirmed a second animal positive for brucellosis in an eastern Idaho herd. The disease is highly infectious and can cause cattle to abort. Idaho State Veterinarian Bill Barton said all animals in the herd have been tested and most results are back.
The department and the industry take a brucellosis finding seriously as another finding in a separate herd would cause the state to lose its brucellosis-free status, wreaking havoc on cattlemen's ability to market their animals.
The industry lost its brucellosis-free status in January 2006. Aggressive action saw the state regain its status in July 2007. Although another animal was found to be suspect for the disease discovered last week, further testing confirmed it was not infected.
