Ill. Admin. Code tit. 8, § 80.30 - Herds Quarantined Because of Suspected Tuberculosis Infection
a) Cattle, bison,
goat, sheep, antelope or cervid herds or flocks suspected of being infected
with bovine tuberculosis (Mycobacterium bovis) shall immediately be quarantined
and the entire herd tuberculin tested. All tuberculin tests on such herds are
to be conducted by veterinarians employed by the United States Department of
Agriculture or the Illinois Department of Agriculture.
b) Procedures for release of quarantine on
such herds are as follows:
1) If the initial
herd test is negative, quarantine shall be released unless epidemiological
evidence, such as infection in surrounding herds or continued exposure to
tuberculosis, necessitates leaving the quarantine in place.
2) If a reactor is disclosed on the initial
herd test, or on test of individual animals in the herd, but the slaughtered
reactor does not exhibit gross lesions indicative of tuberculosis, the
quarantine shall be released upon completion of one additional negative herd
test conducted not less than 60 days following the initial herd test.
3) If a reactor is disclosed on initial herd
test, or on test of individual animals in the herd, and the slaughtered reactor
shows gross lesions indicative of tuberculosis, but Mycobacterium bovis is not
confirmed by laboratory examination of tissues from the slaughtered animal, the
quarantine shall be released following completion of two negative complete herd
retests. The first herd retest shall be conducted not less than 60 days
following the initial herd test on which the reactor was disclosed and the
second herd retest shall be conducted not less than 6 months or more than one
year following the first negative herd retest. After such herds have been
released from quarantine, they must pass a negative herd test annually for two
years following release of the quarantine.
4) If a reactor is disclosed on initial herd
test, or on test of individual animals in the herd, and the slaughtered reactor
shows gross lesions indicative of tuberculosis, with Mycobacterium bovis
confirmed by laboratory examination of tissues from the slaughtered animal, the
herd shall be depopulated if the owner is agreeable and if funds are available.
If the herd is not depopulated, it shall remain under quarantine so long as it
remains intact.
