(a) If a suspect is identified in a herd that has been tested for tuberculosis with negative results within the previous 12 months, the suspect shall be quarantined and subjected to a comparative cervical tuberculosis test, a U.S.D.A. approved deer tuberculosis test or a BTB test. If this tuberculosis test is positive, the deer shall be classified as a reactor and the entire herd shall be quarantined under the conditions set forth in section 60.7 of this Part.

1. (1) The herd quarantine shall be released if the reactor is slaughtered, the necropsy procedures in section 60.6 of this Part followed and the necropsy reveals no visible lesions.
2. (2) The quarantine shall be reinstated if Mycobacterium bovis is microbiologically isolated in the tissue samples submitted pursuant to section 60.6 of this Part and the herd shall be classified as tuberculosis infected.

(b) If a suspect is identified in a herd that has not been tested for tuberculosis within the previous 12 months, the entire herd shall be quarantined under the conditions set forth in section 60.7 of this Part and subjected to a cervical tuberculosis test, a U.S.D.A. approved deer tuberculosis test or a BTB test.

1. (1) If no suspects are disclosed by the herd test, the quarantine shall be released.

2. (2) If suspects are disclosed by the herd test, then either:

   1. (i) a BTB test must be conducted on all suspects. All BTB reactors shall be slaughtered and the necropsy procedures in section 60.6 of this Part followed. If the necropsy reveals no visible lesions, the quarantine may be released. The quarantine shall be reinstated if Mycobacterium bovis is microbiologically isolated in the tissue samples submitted pursuant to section 60.6 of this Part and the herd shall be classified as tuberculosis infected; or

   2. (ii) all suspects up to a maximum of five must be slaughtered and the necropsy procedures in section 60.6 of this Part followed.

      1. (a) If Mycobacterium bovis is microbiologically isolated in the tissue samples submitted pursuant to section 60.6 of this Part, the herd shall be classified as tuberculosis infected.

      2. (b) If no Mycobacterium bovis is microbiologically isolated, then the remaining suspects shall be subjected to a comparative cervical tuberculosis test or BTB test. All reactors shall be slaughtered and the necropsy procedures in section 60.6 of this Part followed.

         1. (1) If Mycobacterium bovis is microbiologically isolated in the tissue samples submitted pursuant to section 60.6 of this Part, the herd shall be classified as tuberculosis infected.
         2. (2) If Mycobacterium bovis is not microbiologically isolated, then the quarantine shall be released.
