Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy in cervids (including white-tailed and mule deer, as well as elk, moose, and reindeer/caribou). CWD is characterized by the accumulation of prions in brain cells that eventually burst, leaving microscopic empty spaces in the brain and giving it a "spongy" appearance. Related diseases include: scrapie in sheep and goats; bovine spongiform encephalopathy, or “mad cow disease” in cattle; transmissible mink encephalopathy; and Creutzfeldt-Jakob disease in humans (see CWD Fact Sheet). CWD can be transmitted directly through animal-to-animal contact as well as indirectly through contaminated soil, plants, and other materials. It can take over 18 months after exposure for an infected animal to develop clinical signs of disease and can appear completely healthy during that time. Once an animal starts showing signs of the disease, it will steadily lose body weight and eventually die. There is currently no vaccine, treatment, or cure for CWD.
To date, CWD has been primarily found in white-tailed deer, elk, mule deer, moose, and reindeer/caribou in North America. The susceptibility of exotic cervids and other wildlife species is currently unknown.
Deer with CWD can appear healthy for 18 months or more before they begin to show signs of disease. During that time, they can spread CWD to other animals and to the environment.
Other deer diseases may present with similar signs. Only a laboratory test can confirm the presence of CWD. Currently, the only USDA-approved test for CWD is a microscopic examination of the brain and lymph node tissue, which must be acquired after death; there is no reliable live animal test for CWD.
Protecting the state’s deer and elk from the harmful impacts of CWD relies on early detection and limiting the exposure of our wildlife and landscapes to the infectious prions that cause the disease. As other states have learned, early detection is critical in being able to effectively manage the disease.
CWD has the potential to greatly impact North Carolina’s deer and elk populations and the tradition of deer hunting in our state. Robust testing is our most powerful tool to identify CWD wherever it occurs on the landscape and to effectively manage its spread.
The NCWRC has been testing for CWD since 1999 in deer that show signs of any disease and through coordinated statewide surveillance. Past statewide surveillance efforts occurred in 2003, 2008 and 2013. Since 1999, over 15,000 samples have been tested. Currently, statewide surveillance occurs each year based on 5-year sampling goals. Samples collected come from a variety of sources including vehicle-kills, voluntary hunter submissions and those supplied from cooperating taxidermists and meat processors.

If you see or have harvested a deer exhibiting signs of disease, leave the animal at the site of the kill and call your local District Biologist or the NC Wildlife Helpline at 1-866-318-2401.
The precautions below should be followed when handling any wild game and help to minimize the risk of exposure and transmission of diseases or foodborne illness.

Never eat meat from a deer that looks sick. Never eat a deer’s:
To be sure you’ve removed all of the parts listed above:
CWD spreads between animals through saliva, urine and feces, either through direct contact or indirectly through environmental contamination, especially in the soil. CWD prions can remain active in the soil for a very long time, even through harsh weather and fire. Soil that has come into contact with contaminated deer parts or fluids can cause CWD in deer for many years – even decades.
Taking precautions that reduce the movement of potentially infected deer parts or fluids around the landscape is crucial to managing the spread of CWD. Learn how to properly dispose of deer harvested in North Carolina.
If you are hunting in a state or province where CWD has been confirmed (see “Where is Chronic Wasting Disease Found?”), public health and wildlife officials recommend taking the following precautions when pursuing and/or handling deer, elk, moose or reindeer/caribou:
If you plan to bring any deer, elk, moose, or reindeer parts back to North Carolina, make sure to familiarize yourself with North Carolina’s Rules for Importation of Deer Carcasses and Carcass Parts.
Anyone returning or transporting a deer, elk, moose or reindeer/caribou from any state, Canadian province or foreign country outside of North Carolina must follow the processing and packaging regulations, which allow the importation of:
See Rules For Importation of Deer Carcasses and Carcass Parts (PDF).

The Centers for Disease Control states that to date, there have been no reported cases of CWD infection in people. However, some animal studies suggest CWD poses a risk to certain types of non-human primates. The CDC states it is important to keep the agents of all known prion diseases (also including mad cow disease and scrapie in sheep) from entering the human food chain. For optimal safety, the NCWRC recommends people do NOT eat:
*Normal field dressing coupled with boning out a carcass will remove most (if not all) of these body parts. Cutting away all fatty tissue will remove remaining lymph nodes.
The abnormal proteins, or prions, that cause CWD are very robust and are not easily destroyed. Prions can be frozen for extended periods of time and still be capable of causing CWD. Extremely high temperatures must be sustained for several hours to reliable destroy a prion. Prions cannot be “killed” with typical sanitizing chemicals but may be manually removed with disinfectant and scrubbing. Hunters should wear gloves and use designated tools/utensils to cut or handle high-risk parts such as the spinal cord, brain and other nervous system tissue. These tools/utensils should not be used to process meat intended for consumption and should be thoroughly sanitized between uses.
Once CWD prions have contaminated the ground in an area, they can remain active and capable of causing CWD for years – even decades. For this reason, taking precautions that prevent CWD from spreading to an area in the first place is crucial.
In addition to robust sampling for CWD statewide, the NCWRC has adopted several rules intended to limit the spread of CWD in North Carolina; most notably a ban on the importation of whole carcass or high risk carcass parts of any cervid (deer, elk, moose, caribou/reindeer) harvested in another state. The agency is working through its CWD Response Plan given the March 31, 2022 confirmation of a positive deer in Yadkin Co. The agency routinely communicates with disease specialists and other agencies to better understand impacts of the disease and strategies to best monitor and manage the spread of the disease over time.
There have not been any reported cases of CWD infection in people. However, the NCWRC recommends hunters follow a list of precautions for handling and deer to limit the potential spread of CWD in the environment and reduce the risks of food-borne illness in general.
Hunters can submit samples from harvested bucks and does of any age. While older bucks are slightly more likely to test positive for CWD, testing deer from all age and sex classes increases our ability to find CWD if and wherever it is present.
This depends on the testing method you choose.
Yes, you may leave the antlers on your deer and still submit it for testing at a testing drop-off station. However, removing the antlers allows more space for other samples and reduces the possibility that holes get poked in the bag. If you do not remove antlers from your deer, you will not receive those antlers back from the NCWRC. They will be discarded.
If you decide to remove the entire skull cap (rather than each individual antler), please take care to place any portions of brain attached to the skull cap in the bag with the deer head.
Expect several weeks to get your deer’s test results back. Staff are making every effort to get samples to the laboratory as quickly as possible, but there are many steps in the process, and there is a wait time for test results at the laboratory. Please be patient as we work to get you results as fast as possible.

On March 31, 2022, results from the first CWD-positive deer in North Carolina were confirmed from buck harvested in Yadkin County. The full range and prevalence of CWD in NC are currently unknown, but the NCWRC is increasing surveillance to better understand the affected area.
