Chronic Wasting Disease – The Laws

Idaho Fish and Game encourages hunters to cooperate with its CWD monitoring program and follow rules implemented to prevent the disease from spreading to Idaho.

Transporting live animals and infected carcasses (particularly brains and spinal tissue) and activities that concentrate animals, such as winter feeding, are all known to accelerate the spread of CWD. Existing, new and pending rules have been crafted specifically to address how CWD can be spread.

Rules to Prevent CWD in Idaho

Currently, a person must obtain a permit from Idaho Fish and Game to import, export, or transport captive mule deer, white-tailed deer and moose. A pending rule may ban all importing of these animals into or through Idaho.

In 2018, the Fish and Game commission approved several rules because of the threat CWD poses to the state’s wildlife.

Hunters are responsible for knowing the rules in the locations outside of Idaho.

  • Urine Ban

    Idaho bans the use of natural cervid urine for big game hunting, which includes urine from deer, elk, moose, reindeer and caribou.

  • Out-of-State Carcass Import Ban

    The state bans importing a carcass or any part of a wild deer, elk or moose from another state, province in Canada or any other country with a documented case of CWD.

    Exemptions to this ban include:
    • Meat that is cut and wrapped
    • Quarters or deboned meat that does not include brain or spinal tissue
    • Edible organs that do not include brains
    • Hides without heads
    • Upper canine teeth
    • Ivories, buglers or whistlers
    • Finished taxidermy
    • Dried antlers
    • Cleaned and dried skulls or skull caps


Pending Rules

The Fish and Game commission approved several other rules, which require legislative approval before taking effect.

  • Winter feeding risk strategy

    Integrate Fish and Game’s CWD risk strategy into winter feeding planning. Winter feeding unnaturally concentrates wildlife, increasing the risk of spreading disease.

  • Restrict winter feeding in CWD zones

    Restrict the public from feeding deer and elk in designated CWD management zones in the event that CWD is discovered in Idaho.

  • Import live cervids

    Ban the importation of live mule deer, white-tailed deer and moose with the exception of allowing existing rehabilitation facilities with approved permits to possess live deer and moose in Idaho.

Hunters need to know where CWD has been documented. This map identifies locations in North America. CWD has also been found in Norway, Finland and South Korea.
