Section 35:15-40-38 - Classification of cattle and bison tested

(a) All responses to an official caudal fold test shall be recorded and the animal classified as suspect and quarantined for retest unless, in the professional judgement of the testing veterinarian, the reactor classification is required.

(b) All animals with a response to a single cervical test shall be classified as reactors. Responses shall be recorded in millimeters.

(c) Responses to a comparative cervical test shall be recorded and plotted on the CCT scattergram. Classification shall be according to the zone in which the animal is plotted on the scattergram. Animals plotting in the negative zone may be reclassified as negative. Animals plotting in the reactor zone may be classified as suspect provided that there has been no known association of the herd with M. bovis. A suspect shall be moved directly to slaughter under permit. The post mortem examination shall be witnessed by a regulatory veterinarian, and specimens shall be submitted for laboratory examination. If the animal fails to disclose gross or microscopic evidence of bovine tuberculosis and a complete epidemiological investigation, including a herd test of all eligible animals, fails to disclose evidence of bovine tuberculosis or exposure thereto, the herd may be considered free of bovine tuberculosis.

(d) Responding animals classified as reactors shall not be retested or reclassified.

(e) Animals responding to the caudal fold tuberculin test that were found negative or suspect by the comparative cervical test shall be reclassified as reactors when included in a herd test that results in the confirmation of bovine tuberculosis in the herd.

(f) In the event new technology and advancements provide alternative testing procedures, which are approved by the USDA, the State Veterinarian may alter testing procedures listed above to conform and utilize the new approved methods and tests.
