(1) Any herd of cattle or bison in which tuberculosis reactors are found will be quarantined. The sale or removal of any animal out of a quarantined herd is prohibited except for removal for immediate slaughter.

(2) Herds in which no gross lesions reactors occur and in which no evidence of Mycobacterium bovis infection has been disclosed may be released from quarantine after a sixty-day negative caudal fold tuberculosis retest of the entire herd.

Herds containing one or more suspects to the caudal fold tuberculosis test will be quarantined until the suspect animals are:

(a) Retested by the comparative-cervical tuberculosis test within ten days of the caudal fold injection; or

(b) Retested by the gamma interferon tuberculosis test and the tuberculosis status of the suspect has been determined; or

(c) Retested by the comparative-cervical tuberculosis test after sixty days and the tuberculosis status of the suspect has been determined; or

(d) Shipped under permit directly to slaughter in accordance with state and federal laws and regulations and the tuberculosis status of the suspect has been determined.

(3) Herds in which Mycobacterium bovis infection has been confirmed and the herd has not been depopulated will remain under quarantine and must pass two tuberculin tests at intervals of at least sixty days and one additional test after six months from the previous negative test. Following the release from quarantine, these herds will also be subject to five annual tests on the entire herd.
