CWD, what hunters can do

February 22, 2019

Chronic Wasting Disease (CWD) is a fatal neurological disease infecting deer and elk across North America. While CWD has not yet been detected in Oregon, there are things hunters can do to help keep it that way.

Beginning January 2020, the use of scent lures derived from deer or elk urine will be banned in Oregon(see below). Why not start doing your part now by going urine free in 2019?

What is CWD?

Chronic Wasting Disease is a fatal, infectious disease that is spread by nose to nose contact between animals and through urine, feces, blood and saliva infecting soils and habitats.

What can you do?

Don’t bring certain animal parts home

If you harvest a deer, elk, moose or caribou in any other state or Canadian province, don’t bring home parts of the animal known to harbor the disease, namely eyes, brains, spinal columns, lymph nodes, tonsils and spleens.

Hunters who bring illegal parts into Oregon will have those parts confiscated and may be liable for the cost of incinerating them.

For more guidance on what parts can be brought into Oregon please see the Parts Ban on page 17 under General Hunting Regulations in the Big Game Regulations. Note that changes to the parts ban regulation took effect Jan. 1, 2019 and now extend the ban to all states and provinces, not just those with a documented case of CWD.

“If we ever document CWD in Oregon, we want to act quickly and will need the support of Oregon hunters. Early detection is our best chance to keep the disease from spreading, should it enter the state. That is why we need the active involvement of hunters and all Oregonians to continue surveillance and keep an eye open for animals that appear sick.” - Colin Gillin, ODFW State Wildlife Veterinarian.

Avoid using deer/elk urine products

ODFW is encouraging hunters to avoid the use of products containing deer or elk urine (scent lures) as part of efforts across North America to reduce the risk of spreading Chronic Wasting Disease (CWD).

Beginning Jan. 1, 2020, the possession and use of deer and elk urine scent lures that contain or are derived from any cervid urine will be banned in Oregon under under HB 2294, passsed by the Oregon Legislature in 2019 in order to reduce the threat of CWD to the state’s deer, elk and moose populations.

Oregon’s ban is in keeping with a recommendation from the Association of Fish and Wildlife Agencies (AFWA). These products are also banned in several other states including Alaska and Louisiana.

The prions that cause CWD can spread through the animal’s body fluids (including urine, feces and saliva) and through nose-to-nose contact between infected animals. Prions shed through bodily fluids can bind to soil minerals and remain infectious for long periods in the environment, spreading to new animals for years as deer and elk come into contact with infected soil and possibly plants containing the prions.

Hunters or businesses who have these products should safely dispose of them by bringing them to an ODFW district office. ODFW staff will arrange for any scents collected to be incinerated in an 1800 degree oven, a temperature known to kill the prion that causes CWD.

“It’s important that these products are not poured down a drain or on the ground when they are discarded. We want to limit the prion that causes the disease from being deposited on the landscape.” - Collin Gillin

Get your animal tested for CWD

Visit roadside sampling station in eastern Oregon or make an appointment

In an effort to keep Oregon’s deer, elk, and moose free from Chronic Wasting Disease, ODFW will host roadside sampling stations to check deer and elk taken in eastern Oregon.

Hunters who are successful in taking a deer or elk in Eastern Oregon are asked to stop at a check station or to contact a local office and make an appointment to bring in the animal’s head so a biologist can take a biological tissue sample tissue. Hunters can also provide a sample if they encounter ODFW staff out in the field during hunting season. In addition to biological sampling, a tooth is requested for the purpose of aging each animal.

Sampling stations will be staffed during mule buck deer season and Rocky Mountain elk season:

Sunday, Sept. 29 and Monday, Sept. 30, 2019 from 9 a.m.–6 p.m.

  • I-84 West at Biggs Junction
  • Prineville weigh station, just east of Prineville on Hwy 26. (Also open Sept. 28 after noon.)

Sunday, Nov. 3and Monday, Nov. 4, 2019 from 9 a.m.-5 p.m.

  • I-84 West at Biggs Junction
  • Prineville weigh station (just east of Prineville on Hwy 26)

If you are interested in having your deer or elk tested for CWD at other times, contact your local ODFW office to set up an appointment. ODFW is most interested in deer and elk that are at least two-years-old (not spikes). For testing, ODFW will need the animal’s head and one or two vertebrae below the skull – keep your sample cool prior to sampling if possible. To avoid cross-contamination, don’t use the same tool to decapitate the animal and to butcher the meat – have dedicated tools for each job.

When you bring your animal in for testing, ODFW also will take a tooth for aging. You should receive a postcard several months later with information about the animal’s age.

If you see or harvest a sick deer or elk, DO NOT EAT THE MEAT. Report it to the ODFW Wildlife Health Lab number at 866-968-2600 or by email to .

Any deer or elk salvaged under Oregon’s new roadkill law is also being tested for CWD.

Take precautions to protect yourself from possible contact with CWD:

  • Don’t take or handle an animal that looks sick.
  • Use rubber or latex gloves when dressing your animal.
  • Avoid handling the eyes, brain, spinal column, spleen, tonsils and lymph nodes when dressing your animal as these areas are where CWD-causing proteins are known to concentrate.
  • Bone out the meat, do not saw through the brain or bone, especially the backbone.
  • Clean your hands and tools thoroughly after dressing an animal. The CWD proteins are very resistant to high temperatures and anti-bacterial soap. Soak your tools in a 50-50 mix of bleach and warm water for one hour to disinfect them.
  • Request that each animal you harvest is processed individually, without meat from other animals mixed in.

How can I tell if a deer or elk Has CWD?

The only way to diagnose an animal with CWD is to sample a part of the brain post-mortem. However, hunters can identify some symptoms of CWD, including, loss of bodily functions, staggering, standing with an exaggerated wide posture, carrying the head and ears low, drooling, drinking large amounts of water, excessive urination and having poor body condition i.e. “wasting” away.

It is important to note the symptoms of CWD are not visible in an animal right away. It may take a few years before an infected animal displays symptoms, but even a healthy looking animal can still be infected.

Can humans get CWD?

There is no evidence that humans can contract Chronic Wasting Disease from eating or handling contaminated meat. However we still recommend you NOT eat any meat from infected animal. Humans are susceptible to other similar diseases such as Mad Cow disease and Creutzfeldt-Jakob disease (CJD) so it’s best to be cautious.

In 2017, Canadian researchers reported they had macaque monkeys contract CWD after consistently eating infected venison; however, the results of the study are not yet published/peer-reviewed.
