Monthly Reports - Affected Herds 2013

Tuberculosis/Brucellosis Working Group

Federal and State Animal Health Officials jointly conduct surveillance for bovine brucellosis and tuberculosis. When infected animals are identified, officials investigate these cases to determine if additional animals or herds of animals are infected.

The reports below provide updates on these investigations and summary information about brucellosis and TB-affected cattle, bison, and captive cervids herds that have been detected during the year. The summaries also include information about herds that were detected in previous years, but are being managed under a test-and-removal plan.
