The Washington Department of Fish and Wildlife (WDFW) has initiated a Chronic Wasting Disease (CWD) surveillance program. Department staff are collecting samples year round in specific surveillance units in Eastern Washington (see map).

CWD is a fatal neurologic disease of cervids- deer, elk, and moose- caused by an infectious prion protein and transmitted from animal to animal or through contaminated environments. Most animals with CWD appear normal until the end stages of the disease when they show signs of weight loss, lethargy, drooping ears, excess salivation and urination, and loss of fear of people. There is no known cure for CWD.

CWD has not been detected in Washington, but has been in 27 states, most recently in Idaho, and 4 Canadian Provinces. Testing tissue samples collected from the head and neck of an animal from carcasses is the only way to determine if it is infected.

CWD sampling locations and times

WDFW offices

If you harvest or salvage a road-killed deer, please contact WDFW at 509-892-1001 or email if you would like your deer tested for CWD. You can also arrange sample collection with the Inland Northwest Wildlife Council (INWC) by calling 509-487-8552 to make arrangements to have it tested. Only the head of the animal is required for sampling.

Find your CWD test results

You can look up your CWD test results by entering your WILD ID or Salvage Permit ID in the test results lookup tool.

Help prevent the spread of CWD

To prevent spreading prions that cause CWD, either field dress and leave all inedible parts of your harvested animal at the kill site or dispose of inedible parts in a licensed landfill. You can also double bag and place them in your household garbage.

If you harvest deer, elk, or moose outside Washington in states or provinces with CWD, by law (WAC 220-413-030), only the following items may be imported to Washington:

  • Meat that has been de-boned in the state or province where it was harvested.
  • Skulls and antlers, antlers attached to the skull plate, or upper canine teeth (bugler, whistlers, ivories) from which all soft tissue (including velvet) has been removed.
  • Hides or capes without heads attached.
  • Tissue imported for use by a diagnostic or research laboratory.
  • Finished taxidermy mounts.

If you are notified by another state or provincial fish and wildlife agency that the animal you harvested tested positive for CWD, you have 24 hours to notify WDFW by calling 360-902-2515.

Health and human safety

While there is no scientific evidence of CWD being transmitted to humans from animals, the Centers for Disease Control and Prevention recommends not consuming animals that test positive for CWD. WDFW advises hunters to:

  • Avoid harvesting any animal that appears sick or behaves strangely.
  • Wear disposable gloves while field dressing game.
  • Thoroughly wash hands and equipment after processing carcasses.
  • Avoid consuming parts where the CWD prions accumulate including brain, spinal cord, eyes, spleen, pancreas, tonsils, and lymph nodes.
  • Avoid cutting through bone, brain, or spinal cord.
  • Disinfect processing tools by soaking in household bleach (>2% free chlorine ) at a 40% solution (with water) for a minimum of 5 minutes.
  • Remove any tissue pieces from tools before soaking. Rinse tools after soaking. 

Reporting suspected CWD cases

Please help the Washington Department of Fish and Wildlife (WDFW) monitor the health of our deer, elk, and moose populations. While hunting or recreating, if you observe a sick or dead deer, please report it to your regional WDFW office or use this online reporting form.
