Section 21.32.4.9 - BRUCELLOSIS TEST REQUIREMENTS FOR CATTLE AND BISON

A. For all states, regardless of brucellosis class, cattle originating from any "brucellosis certified free" herd may enter New Mexico without an entry test, provided the following information is recorded on the official health certificate:

B. There is no brucellosis test required for spayed heifers and steers.

C. Brucellosis free states: All cattle must meet federal interstate regulation requirements for "class free" states, in addition to New Mexico requirements.

D. Class A states: All females and bulls over 18 months of age must be tested and negative within 30 days prior to entry into New Mexico, except heifers that are officially vaccinated for brucellosis and under 24 months of age if beef and under 20 months of age if dairy. All cattle must meet federal interstate requirements for "class A" states, in addition to New Mexico requirements.

E. Class B states: All females and breeding bulls over 8 months of age must be tested and negative within 30 days prior to entry into New Mexico, except heifers that are officially vaccinated for brucellosis and under 24 months of age if beef, and under 20 months of age if dairy. All cattle must meet federal interstate requirements for "class B" states, in addition to New Mexico requirements. Test eligible animals over 8 months of age will be quarantined at destination for a retest for brucellosis at the owner's expense, unless waived by the board, between 60 and 90 days after the entry test date. Untested test eligible animals may go direct to slaughter or direct to a quarantined feedlot provided they are "S" branded and move on an "S brand" permit or they move direct to slaughter in a "sealed" vehicle. No heifer calves can move from infected herds, unless they are "S" branded or spayed. "S" branded heifers from infected herds can go only to slaughter or quarantined feedlot. Spayed heifers will be treated like steers. Special permits may be granted by the state veterinarian to spay heifers on arrival.

F. Testing or vaccination requirements for class A and class B states are not required when going directly from the farm or ranch of origin to a federally approved slaughter plant for slaughter or to a New Mexico quarantined feedlot or when going to an approved market where the qualification for brucellosis will be handled at the market.

G. Class C states: No sexually intact cattle, regardless of age, will be allowed to be moved into New Mexico, except "S" branded animals going to slaughter or quarantined feedlots. The restrictions will not affect spayed heifers or steers. The only cattle exempt from these requirements are cattle from "certified brucellosis free herds," which must have a negative test within 30 days prior to entry. Special permits may be granted by the state veterinarian to spay heifers on arrival.

H. All tests shall be at the owners expense.
