The primary objective of the cervid bTB herd accreditation program is to eliminate M. bovis, the causative agent of bTB, in farmed/captive cervids as part of a comprehensive approach to eradicate bTB in domestic cattle and bison in the U.S. All farmed/captive cervids destined for interstate movement are required to be tested for bTB.
Herds that participate in the APHIS Cervid bTB Herd Accreditation Program must test their entire herd of cervids over 12 months of age, negative for bTB two times in 9 to 15 month intervals to establish an Accredited Free herd. Non-natural additions of any age must also be tested on the same schedule. The accreditation is valid for 33 to 39 months from the original anniversary date and a negative whole herd retest must be performed in that period of time to maintain the accredited status. Animals from the Accredited Free herds are allowed to be moved interstate at any time without further testing
Details on the bTB testing requirements for interstate movements of cervids from monitored herds, qualified herds, and accredited herds from modified accredited States and zones are provided in the federal regulations (9 CFR Parts 77 and 86) and in the 1999 UM&R on Bovine Tuberculosis Eradication. A new bovine Brucellosis /TB proposed rule will replace the existing regulations and UM&R once published in the Federal Register.
