New Mexico split-state regulations

New Mexico’s plan for halting the spread of bovine tuberculosis (TB) was recently approved by USDA. The plan allows much of the state to designate a Modified Accredited Advanced (MAA) zone that encompasses the entire area of Curry and Roosevelt counties. The balance of New Mexico is returned to “TB Free” status. The rule allowing return to split state status for New Mexico was published in the Federal Register and became effective on March 23, 2009. The requirements incorporated into the MAA Zone Memorandum of Understanding between the state of New Mexico and USDA focus on four basic requirements:

1) Sexually intact cattle will be required to have a negative TB test within 60 days to leave the MAA zone, including those being sent to sale barns outside the zone. Cattle being sent directly to slaughter, as well as feeder heifers and steers, are exempt from this requirement.

2) New Mexico Livestock Board (NMLB) is to be notified of all livestock movement between points within the MAA zone. Contact NMLB livestock inspector or the NMLB office for details.

3) All sexually-intact New Mexico dairy cattle, inside or outside the MAA zone, will be required to have a negative TB test within 60 days of entering or re-entering any dairy herd in the state.

4) All sexually intact cattle in the MAA zone will be required to have official identification in order to leave the zone for any purpose. Nursing calves are exempt from this requirement.

NMLB will be holding local meetings in the Clovis/Portales area with producers and other interested parties to discuss and explain the new MAA zone and its associated testing and movement requirements. All are welcome to attend. Individuals may also direct their questions to the NMLB office and can access the NMLB Web site at www. for posted information. — WLJ
