Effective July 23, 2007, Idaho's brucellosis classification was changed from 'Class A' to 'Class Free.' This may reduce the testing required for animals being exported. Please continue to check with the state of destination for requirements, as they may require testing to continue. If you have any questions regarding this status change you may view the USDA News Release, or contact ISDA at (208) 332-8540.
Idaho Code requires that all intact female cattle in the state used for breeding, grazing or dairying purposes be officially vaccinated against brucellosis. ISDA requires the vaccination of all imported intact female cattle and domestic bison 4 months (120 days) and older prior to entering the state. If cattle are of Idaho origin they must be vaccinated prior to becoming 1 year of age. Cattle that are older than 1 year and are of Idaho origin may qualify to be adult vaccinated for brucellosis. If you have cattle you would like to get adult vaccinated, please have your veterinarian contact the department at (208) 332-8540.
