     (a) Are maintained on common grounds under common ownership or supervision, including an animal which may be geographically segregated; and

     (b) Have interchange or movement of animals without regard to health status.

     (3) "Herd known to be infected with mycobacterium paratuberculosis" means a herd in which bovine, bison, or other animals on the premises have been determined to be infected with mycobacterium paratuberculosis by an official mycobacterium paratuberculosis epidemiologist or state veterinarian;

     Section 3. Test Requirements. (1) A herd not known to be infected with mycobacterium paratuberculosis within the last five (5) years shall be tested as follows:

     (a) All animals twenty (20) months of age or older shall have blood collected and a fecal culture for an official mycobacterium paratuberculosis test.

     (b) A negative herd blood test and negative fecal culture may qualify the herd to be designated as a Phase III herd and the herd may then be classified as a mycobacterium paratuberculosis (Johne's) test negative herd.

     (c) To maintain a Johne's test negative herd, the herd shall have:

     1. An annual herd test of all animals twenty (20) months of age or older; and

     2. A fecal culture conducted every third year.

     (d) If a Johne's positive animal is classified, the herd shall be tested following the requirements established in Section 3(2) of this administrative regulation.

     (2) A herd known to be infected with mycobacterium paratuberculosis within the last five (5) years shall be treated as follows:

     (a) All animals twenty (20) months of age or older shall have blood collected for an official mycobacterium paratuberculosis test.

     (b) All animals twenty (20) months of age or older that are positive to an official serology test shall:

     1. Have a fecal culture for Johne's;

     2. If removal of the animal is requested after a positive official serology test, be "J" punched as set out in paragraph (c) of this subsection and consigned to slaughter only. If the animal is to be slaughtered for home consumption, it shall be slaughtered in an approved state or federal facility; and

     3. Not remain on the premises without being fecal culture tested for Johne's.

     (c) A Johne's fecal culture positive animal shall be immediately and permanently identified by punching the letter "J" through the left ear of the animal along with placement of an official eartag, if an official eartag is not already in place. The "J" punch shall be performed by an agent of the board of agriculture as designated by the state veterinarian. An animal so identified shall be consigned to slaughter when removed from the premises. The herd shall be eligible for a second herd test six (6) months after the last known Johne's positive animal has been removed from the herd. The official mycobacterium paratuberculosis epidemiologist and state veterinarian shall determine which tests shall be conducted based on the herd's Johne's prevalence and risk classification.

     (d) A complete herd test of all animals twenty (20) months of age or older shall be conducted at six (6) month intervals until the herd is classified as a Johne's test negative herd.

     (3) Johne's herd risk classification.

     (a) A herd with a Johne's infection rate greater than five (5) percent shall be considered a "high risk" herd.

     (b) The herd risk classification shall determine the types of test required to establish a Johne's test negative herd. The official mycobacterium paratuberculosis epidemiologist and the state veterinarian shall determine test requirements.

     (4) Herd addition test requirements.

     (a) An animal twenty (20) months of age or older shall have a negative serology test within thirty (30) days prior to change of ownership.
