Panel adopts domestic-cervid rules aligning testing, fences with 2024 law; conservation group urges stronger CWD monitoring

The Idaho Senate Agricultural Committee adopted a set of rules to align captive cervid regulations with last year’s House Bill 591 and to clarify chronic wasting disease (CWD) testing and quarantine procedures.

Dr. Scott Lively, administrator of the Division of Animal Industries and state veterinarian, presented the changes. He told the committee the rule package updates definitions and testing standards to reflect scientific and statutory changes. “A valid CWD test requires the OBEX (brain stem) and the retropharyngeal lymph nodes,” he said, summarizing the laboratory-standard clarification the rule codifies.

The rule package also removes a prior House Bill provision that would have required a double-perimeter fence at facilities where a CWD-positive captive animal was detected. Under the adopted rule, a regularly inspected single perimeter fence suffices if the department inspects and maintains the fence. The rule also clarifies that a producer with multiple facilities under common ownership may, under quarantine, move animals between those facilities when appropriate.

Dr. Lively described the state’s testing targets: no less than 10% of harvested animals should be tested year to year and 100% of animals that die for reasons other than harvest must be tested when tissues are viable. He said the department has removed the prior requirement to file a tissue-submission waiver when a carcass is too decomposed to test; instead, the department will track compliance through year-to-year testing records and pursue enforcement only when a pattern of noncompliance appears.

Public testimony focused on monitoring and risk to wild herds. Jonathan Oppenheimer, government relations director for the Idaho Conservation League, told the committee his organization supports the rule changes as written but flagged concerns about monitoring sufficiency and the risk of disease introduction from imported elk. He noted recent positive CWD findings at two elk farms and urged the department and Fish and Game to consider interim or emergency measures to strengthen surveillance.

Committee members asked detailed questions about the waiver process and what tissues are required for testing. Senator Taylor asked why the waiver requirement was removed; Dr. Lively said the waiver requirement was impractical when tissues were too degraded for testing and that the department would focus on facilities’ compliance trends over time. The committee also discussed limits on movement between facilities under common ownership during quarantine.

A motion to approve docket 0204192401 carried by voice vote. Committee members and the department said they plan negotiated rulemaking to refine processes going forward.

Why it matters: CWD is a fatal, long-lived prion disease of cervids; the rules affect testing regimes, quarantine authority, and facility requirements for captive elk and deer—policies with implications for disease risk in both captive and wild populations.
