8 Colo. Code Regs. § 1201-16, pt. 4

Current through Register Vol. 47, No. 22, November 25, 2024

Part 4 - Infected Flocks Containing Animals with Scrapie

4.1. In any flock in which scrapie is diagnosed, the state veterinarian will conduct an investigation within 7 days upon receipt of notice of infection. The premises and all sheep and goats on the premises may be placed under quarantine by the State Veterinarian. For any premises, sheep or goats placed under quarantine, the owner of the flock must complete the following:

4.1.1. All sheep and goats must be identified with official identification and inventoried as to sex, age, breed and species.

4.1.2. An epidemiological tracing must be completed as to the origins of animals and the destination of animals moved from the flock; and USDA will determine a designation of infected or source flock within 15 days; and

4.1.3. A flock plan must be developed, signed by all parties, and approved by the State Veterinarian or his representative.

4.2. Any such quarantine will remain in effect until the animals are identified with the appropriate USDA approved methods, epidemiology is completed, and a flock plan has been developed and agreed upon and signed by all parties. The flock plan may be replaced with a PEMMP developed mutually by the owner, his veterinarian, and state or federal officials and approved by the State Veterinarian.

4.3 Flock plans for infected flocks within Colorado must be approved by the State Veterinarian prior to implementation. The flock plan must address, but is not limited to:

4.3.1. Animal identification and record keeping;

4.3.2. Disinfection and sanitary measures;

4.3.3. Lambing or kidding management;

4.3.4. The classification and disposition of affected and high-risk animals within the flock;

4.3.5. Animal sales and movements of animals from the flock;

4.3.6. Where appropriate, and as a part of a comprehensive flock management plan, approved live-animal screening tests and genetic tests for scrapie resistance will be used to evaluate the risk status of individual animals within the flock. Genetically susceptible genotype animals must be killed and destroyed or sent to a research facility. Flock plans may include breeding only with homozygous scrapie resistant rams for the duration of the flock plan; and

4.3.7. At the discretion of the State Veterinarian, a second genotyping sample may be required at the owner's expense. If there is a discrepancy in test results indicating a QQ genotype, the animal will not be permitted entry into Colorado until the discrepancy is resolved with the approval of the USDA reference laboratory, the National Veterinary Service Laboratory (NVSL).

4.4 The flock plan will remain in effect until all scrapie susceptible animals have been removed from the flock. After all scrapie susceptible animals have been removed from the flock, and only homozygous scrapie resistant rams are used for breeding in the flock, the flock plan may be replaced with a PEMMP developed mutually by the owner, his veterinarian, and state or federal officials and approved by the State Veterinarian.
