Sec. 7.
(a) The
state veterinarian may release the Pseudorabies quarantine placed on an
infected swine herd when all animals that have tested positive for Pseudorabies
have been removed from the premises, no animal on the quarantined premises
shows signs of Pseudorabies infection, and at least one (1) of the following
sets of requirements is completed:
(1)
Complete depopulation of the infected herd occurs meaning that all swine in the
herd are removed from the premises and delivered for slaughter. The premises is
cleaned and disinfected under the direction of the state veterinarian. No swine
have been on the premises for thirty (30) continuous days following the
completion of cleaning and disinfecting. The state veterinarian may approve
release of a quarantine in less than thirty (30) days after cleaning and
disinfecting if doing so advances Pseudorabies eradication.
(2) Complete depopulation of the infected
herd meaning that all swine in the herd are removed from the premises and
delivered for slaughter. No swine have been on the premises for a period of not
less than ninety (90) continuous days from the date the depopulation is
complete. Cleaning and disinfecting is not required if a veterinary
epidemiologist or the state veterinarian determines that Pseudorabies
eradication will be advanced by releasing the quarantine without cleaning and
disinfecting at the site.
(3)
Progeny under eight (8) weeks of age may be weaned, isolated from a quarantined
herd under direction and supervision of the state veterinarian and pass two (2)
negative official Pseudorabies tests or approved differential Pseudorabies
tests not less than thirty (30) nor more than sixty (60) days apart. However,
the first qualifying test will be conducted on pigs three (3) months of age or
over. The first test must be a complete test, and the second test must be at
least the designated percentage of animals as outlined in section 8.5(a) of
this rule. The swine herd is eligible for qualified Pseudorabies-negative herd
status if the second negative test is a complete test of the
population.
(4) All swine positive
to an approved differential or official Pseudorabies test are removed from the
premises. The premises are cleaned to the extent feasible. The remaining swine
in the herd are tested as follows:
(A) Not
less than thirty (30) days after the Pseudorabies-infected swine are removed
and the premises is cleaned, all swine over six (6) months of age must test
negative for Pseudorabies, and an official random sample of thirty (30) swine
between two (2) and six (6) months of age must test negative for
Pseudorabies.
(B) Between thirty
(30) and sixty (60) days after the tests required under clause (A) are
completed, an official random sample of swine over six (6) months of age must
test negative for Pseudorabies. An official random sample of swine between two
(2) and six (6) months of age must test negative for Pseudorabies. The exact
number of animals to be tested shall be determined under section 8.5(a) of this
rule. Additional negative herd tests may also be required. Infected herds
become eligible for qualified Pseudorabies-negative herd status if two (2)
complete herd tests have been conducted on all swine over six (6) months of age
plus two (2) random samples of progeny two (2) to six (6) months of age and all
swine tested are negative. The two (2) tests must be at least thirty (30) days
apart.
(5) All swine
present on the date the herd was quarantined for Pseudorabies have been
removed, and there have been no clinical signs of Pseudorabies infection in the
herd for at least six (6) months. Two (2) successive random tests of a
percentage of the herd over six (6) months of age and of a percentage of the
progeny over four (4) months of age have been determined to reveal no
Pseudorabies infection. The two (2) tests must be at least ninety (90) days
apart. The percentage of animals to be tested shall be determined under section
8.5(a) of this rule. Herds released from Pseudorabies quarantine under this
subdivision must be tested for Pseudorabies and test negative using a
percentage test one (1) year after the quarantine is released. This subdivision
applies only to parts of the state classified Stage I, Stage II, and Stage III
under the Program Standards.
(6)
High risk herds may be released from quarantine when a percentage of the swine
in the herd are tested and found negative for Pseudorabies. The percentage of
animals to be tested shall be determined under section 8.5(a) of this
rule.
(7) In swine herds that
contain no breeding swine and that do not receive swine from any premises
quarantined for Pseudorabies, one (1) of the following sets of requirements are
met:
(A) The herd is depopulated meaning that
all swine in the herd are removed from the premises and delivered for
slaughter. The premises is cleaned and disinfected and at least seven (7) days
pass after cleaning and disinfecting before any animals are moved onto the
premises. The herd tests negative for Pseudorabies infection using an official
random sample test (95/10) under the Program Standards conducted at least
thirty (30) days after the depopulation was completed.
(B) The herd tests negative for Pseudorabies
infection twice, the first test an official random sample test (95/5) under the
Program Standards, the second test conducted at least thirty (30) days
following the first test and must be an official random sample test (95/10)
under the Program Standards.
(b) The state veterinarian shall make the
final determination to release any quarantine.
(c) After any herd is released from
Pseudorabies quarantine, the herd must be tested for Pseudorabies between one
hundred fifty (150) and one hundred eighty (180) days after the quarantine is
released utilizing an official random sample test (95/10) under the Program
Standards.
(d) A qualified
Pseudorabies-negative herd that has been determined to be infected with
Pseudorabies may qualify for reinstatement as a qualified Pseudorabies-negative
herd if the quarantine is released and the owner meets all of the following
conditions:
(1) All swine in the herd six (6)
months of age and older test negative for Pseudorabies using an official
Pseudorabies test.
(2) A random
sample of swine two (2) to six (6) months of age is tested for Pseudorabies
using an official Pseudorabies test and all swine tested are
negative.
(3) Between thirty (30)
and sixty (60) days after the tests described in subdivisions (1) and (2) are
completed, the tests described in subdivisions (1) and (2) are
repeated.
(e) All tests
required in this section must be an approved differential or official
Pseudorabies test.
