Section 345IAC3-5.1-7. Release of quarantine; testing

   (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.
