Universal Citation: 4 TX Admin Code ยง 43.22
Current through Reg. 49, No. 38; September 20, 2024
(a) Accredited Herd Plan.
(1) Animals to be
tested. Testing of herds for accreditation or reaccreditation shall include all
Cervidae and all other hoof stock over 12 months of age and animals under 12
months of age that are not natural additions, except that animals under 12
months of age that are not natural additions that were born in and originate
from an accredited herd will not need to be tested.
(2) Qualifying standards. To meet the
requirements for accredited herd status, the herd must pass at least two
consecutive official tests for tuberculosis at nine to 15 month intervals with
no evidence of bovine tuberculosis disclosed. Herds meeting these standards
shall be issued a certificate by the Commission.
(3) Additions. Herd additions must originate
directly from one of the following and have no exposure to cervids from herds
of lower status:
(A) An Accredited
Herd.
(B) A Qualified or Monitored
Herd. Provided, the individual animals for addition were negative to an
official tuberculosis test conducted within 90 days prior to entry and isolated
from members of the accredited herd until negative to an official tuberculosis
test conducted at least 90 days following entry.
(C) A herd not meeting the requirements of
subparagraph (A) or (B) of this paragraph. Individual animals for addition must
be isolated from all other members of the herd of origin, and pass two negative
official tests for tuberculosis conducted at least 90 days apart, with the
second test conducted within 90 days prior to movement to the premises of the
accredited herd. The additions must be kept in isolation from members of the
accredited herd until negative to an official tuberculosis test conducted at
least 90 days following the date of entry.
(D) Animals added under this subparagraph and
subparagraph (B) of this paragraph shall not receive accredited herd status for
sale or movement purposes until they are negative on a retest 90 days after
entry.
(4)
Reaccreditation. To qualify for reaccreditation, the herd must pass a test
within a period of 33 to 39 months of the anniversary date. The accreditation
period will be 36 months from the anniversary date (not 36 months from the date
of the reaccreditation test).
(b) Monitored Herd Plan.
(1) Requirements. Identification records must
be maintained on animals over one year of age slaughtered, inspected, and found
negative for tuberculosis at an approved slaughter facility or at an approved
diagnostic laboratory. Such records may also include animals that have been
tested negative for tuberculosis in accordance with the requirements for
interstate movement. A monitored herd must identify animals over one year of
age at slaughter, and animals tested negative for interstate movement at a rate
to detect infection at a 2.0% prevalence level with 95% confidence evenly
distributed over a three year period. No less than half of the qualifying
animals must be slaughter inspected. This rate would require a maximum of 178
animals. The qualifying total herd size is the annual average of herd members
over one year of age maintained during the initial test period, which period
shall not exceed three years.
(2)
Maintenance of Monitored Herd Status. For monitored herd status to be renewed,
an annual report shall be submitted by the person, firm or corporation
responsible for the management of the herd to the Commission prior to the
anniversary date. This report shall give the number of animals currently in the
herd and the number of animals over one year of age, identified and slaughtered
at a State/Federal approved slaughter facility and animals tested negative for
tuberculosis in accordance with the requirements for interstate movement during
the preceding year. The number of slaughter inspections and animals
tuberculosis tested in accordance with the requirements for interstate
movements reported in any given year must be at least 25% of the number
required to initially qualify a herd of this size for monitored herd status,
provided, however, that during each consecutive three year period, 100% of the
initial qualifying total shall be achieved.
(3) Additions. Herd additions must originate
from one of the following:
(A) an Accredited
Herd.
(B) a Qualified or Monitored
Herd. Provided, the individual animals for addition were negative to a
tuberculosis test conducted within 90 days prior to entry.
(C) a herd not meeting the requirements of
subparagraph (A) or (B) of this paragraph. Individual animals for addition must
be isolated from other members of the herd of origin, and pass two negative
official tests for tuberculosis, conducted at least 90 days apart, provided
that the second test was conducted within 90 days prior to movement to the
premises of the monitored herd. The additions must be kept in isolation from
all members of the monitored herd until negative to an official tuberculosis
test conducted at least 90 days following the date of entry. Animals added
under this paragraph shall not receive monitored herd status for sale purposes
until they are negative to a retest 90 days after entry.
(c) Qualified Herd Plan for Cervidae.
(1) Animals to be tested. Testing
of herds for qualified herd status shall include all cervidae over 12 months of
age and any animals under 12 months of age that are not natural additions,
except such animals originating from accredited, qualified, or monitored
herds.
(2) Qualifying Standards. To
meet the requirements for qualified herd status, the herd must pass one
official test for tuberculosis, within a seven month period with no evidence of
bovine tuberculosis disclosed. The qualified herd status remains in effect for
12 months following the qualifying test.
(3) Additions. Herd additions must originate
directly from one of the following:
(A) an
accredited herd;
(B) a monitored or
qualified herd, provided that the individual animals for addition were negative
to an official tuberculosis test conducted within 90 days prior to
entry;
(C) a herd not meeting the
requirements of subparagraph (A) or (B) of this paragraph. Individual animals
for addition must be isolated from other members of the herd of origin and must
have negative results to two official tests for tuberculosis, conducted at
least 90 days apart, provided that the second test was conducted within 90 days
prior to movement to the premises of the qualified herd. The additions must be
kept in isolation from all members of the qualified herd until they are
negative to an official tuberculosis test conducted at least 90 days following
the date of entry.
(4)
Animals added under paragraph (3)(C) of this subsection shall not receive
qualified herd status for sale or movement purposes until they are negative to
a retest 90 days after entry.
(d) Surveyed Herd.
(1) Requirements--Surveillance records must
be maintained on all animals over one year of age harvested and inspected or
tested without evidence of bovine tuberculosis:
(A) at an approved slaughter facility with
state/federal meat inspection, approved diagnostic laboratory; and/or
(B) routine tuberculosis testing of
individual animals or consignments performed by a designated accredited
veterinarian; and/or
(C) other
appropriate methods of surveillance approved by a representative of the
TAHC.
(2) A surveyed
herd must identify animals at a rate to detect infection at a 2.0% prevalence
level with 95% confidence. This rate would require an annual survey of a
minimum of one-third of the total number of animals prescribed in appendix 1
for each specified herd size.
(3)
Qualification and maintenance of surveyed herd status. An annual report shall
be submitted by the person, firm, or corporation responsible for management of
the herd to the Commission at the time of qualifying and prior to each
anniversary date. The report shall include the estimated number of breeding age
animals currently in the herd and the number of animals over one year of age
surveyed during the preceding year.
(e) Status of newly assembled herds. A newly assembled herd shall assume the herd status of the herd from which the animals originated. If the herd is assembled from more than one herd, it shall assume the status of the originating herd with the lowest status. A newly assembled herd shall also assume the testing schedule of the herd which status it assumes. These animals must have no exposure to cervidae from herds of lesser status than the herd of origin which is determining the status of the newly assembled herd.
