Disease control

1. Anthrax. a. Sheep susceptible to anthrax located on farms where anthrax has been diagnosed shall be vaccinated. Animals must be quarantined for thirty days after the death of the last animal or thirty days following vaccination, whichever occurs last. b. Sale of hides removed from animals infected with anthrax is prohibited. 2. Brucella ovis. a. Flocks may be tested to obtain brucella ovis negative flock status. b. To qualify a flock as a negative brucella ovis status flock, two negative tests for brucella ovis must have been administered, forty-five to sixty days apart, during the same year, to all rams one year of age or older, and thereafter a yearly negative test must have been administered to all rams in the flock one year of age or older. 3. Scrapie. a. Identification. (1) The owner of a flock or the owner's agent officially shall identify all animals upon change of ownership to the flock of birth or the flock of origin, if the flock of birth cannot be determined. Sheep are required to be officially identified except: (a) Slaughter sheep (sheep in slaughter channels) less than eighteen months of age. If a sexually intact sheep is sold at an unrestricted sale (any sale that is not a slaughter or feeding for slaughter sale), it must be identified. (b) Wether sheep less than eighteen months of age. (c) Animals shipped directly to an approved slaughter facility or an approved auction market, when all the animals in a section of a truck are from the same premises of origin and are accompanied by an owner's statement. (d) Animals moved for grazing or similar management reasons whenever the animals are moved from a premises owned or leased by the owner of the animals to another premises owned or leased by the owner of the animals. (2) An animal that is required to be individually identified or that originates from any area where, in the determination of the board, scrapie may exist may not be sold, transported, received for transportation, or offered for sale or transportation in intrastate commerce unless each animal is identified in accordance with this section. (3) A person may not remove or tamper with any means of identification required to be on animals pursuant to this section while the animals are in intrastate commerce, and, at the time of slaughter, animal identification must be maintained throughout postmortem inspection. (4) The recommended scrapie eradication uniform methods and rules as they appear in publication of USDA-APHIS-VS are adopted and constitute a rule of the board, unless otherwise ordered by the board.
