WAC 16-86-150
Tuberculosis quarantine and release. (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 or 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.
