      NECESSITY, FUNCTION, AND CONFORMITY: KRS 257.020(3) requires the board to prevent, control, and eradicate any communicable disease of livestock. KRS 257.030(4) authorizes the board to promulgate administrative regulations necessary to administer any provision of KRS Chapter 257. This administrative regulation establishes procedures for approving a pseudorabies herd cleanup plan and to eradicate pseudorabies from a porcine herd or animal upon a determination of infection or exposure to pseudorabies.

 

      Section 1. Definitions. (1) "Breeding swine" means male or female porcines which are sexually intact, six (6) months of age or older, and specifically used or intended to be used for reproduction.

      (2) "Circle testing" means serological sampling of swine required by an official pseudorabies epidemiologist in herds that are within one and one-half (1.5) miles of an infected herd.

      (3) "Depopulation" means a procedure that clears the premises of all swine.

      (4) "Exposed swine" means any swine that has been in contact with an animal infected with pseudorabies. This includes all swine in an infected herd.

      (5) "Herd" means all porcine animals maintained for any purpose on common grounds, under common ownership or supervision, including animals which may be geographically segregated, and have exchange or movement of animals without regard to health status.

      (6) "Indemnity" means monies paid to the owner by state or federal agencies in addition to the salvage value of the swine.

      (7) "Infected herd" means a herd in which swine have been determined, by an official pseudorabies epidemiologist or state veterinarian, to be infected with pseudorabies.

      (8) "Mandatory depopulation" means the required removal of all swine from a premises where an official herd cleanup plan was not developed, followed, or was ineffective in the elimination of pseudorabies.

      (9) "Official depopulation plan" means a depopulation plan for a herd with an infection rate of more than ten (10) percent and where indemnity is paid on all breeding swine in the herd.

      (10) "Official herd cleanup plan" means a plan developed by an official pseudorabies epidemiologist in consultation with the herd owner and his veterinary practitioner and approved by the state veterinarian, for the purpose of eliminating pseudorabies from the herd.

      (13) "Official random sample test" means a group sampling of swine utilizing serological tests which provide a ninety-five (95) percent probability of detecting pseudorabies in a segregated group of swine when at least ten (10) percent of the animals tested are seropositive for pseudorabies.

      (14) "Positive animal" means an animal which has given a positive reaction to an official test for the detection of pseudorabies, and is so classified by an official epidemiologist, or if the pseudorabies virus has been found in the body of an animal or in the body discharge of an animal.

      (15) "Pseudorabies" means a communicable, contagious, and infectious disease caused by a herpes virus affecting livestock and other animals.

      (16) "Pseudorabies monitored feeder pig herd" means a swine breeding herd that has tested negative to an official pseudorabies serologic test during the last twelve (12) months, pursuant to Section 2 of this administrative regulation.

      (17) "Pseudorabies vaccine" means a pseudorabies vaccine licensed by the United States Department of Agriculture pursuant to 21 USC 151 et seq. and 9 CFR 85.1.

      (18) "Qualified pseudorabies negative herd" means a swine herd that is free of pseudorabies and maintains a pseudorabies free status as determined by periodic testing of breeding swine.

      (19) "Salvage value" means the carcass worth of an animal.

      (2) Feeder pigs from qualified pseudorabies negative herds with a valid Certified Feeder Pig Producer Card (CFPP), or herds with a valid Pseudorabies Surveillance Card (PS) may be moved without individual identification from an originating Kentucky farm to another Kentucky farm for purposes of feeding for slaughter if all feeder pigs on the recipient farm are from the same originating herd. Approval of the State Veterinarian and compliance with requirements of 302 KAR 20:210 shall be required before swine may be moved.

      (3) Swine originating from a state which qualifies for Stage IV or V under the national program standards may enter Kentucky without a test unless a test prior to entry for exhibition or sale is required by the state veterinarian because there has been a break in Stage IV or Stage V status or there has been an exposure to pseudorabies.

 

      Section 6. Indemnity. (1) State indemnity funds, if available, shall be paid in the following amounts for swine sent directly to slaughter:

      (a) Twenty-five (25) dollars per head for all seropositive breeding swine if test and slaughter, voluntary depopulation, or a herd plan other than official depopulation or mandatory depopulation is the herd cleanup plan.

      (b) If test and slaughter was the official herd cleanup plan, the herd shall have two (2) negative tests. The first test shall be no less than thirty (30) days after the last positive animal has been sold to slaughter. The second test shall be more than sixty (60) days after the last positive animal is sold for slaughter. The second test shall include all breeding swine; all other swine on the premises shall be randomly sampled.

      (2) Other quarantined herds shall not be released until after a negative test, as directed by the official pseudorabies epidemiologist, and quarantine release approved by the state veterinarian.
