Chronic Wasting Disease
Currently, chronic wasting disease (CWD) has not been detected in Nevada, and state wildlife officials are urging residents heading out of state to hunt deer and elk to process their game before bringing it back home to reduce the risk of introducing the disease into the the state.
What Is CWD?
CWD is a transmissible spongiform encephalopathy (TSE) that is found in deer and elk. It is believed to be caused by a mutated protein, called a prion that attaches to, and transforms healthy brain proteins into disfigured mutations that lead to a deterioration of the brain, and ultimately death of the animal.
CWD is similar but different from scrapie ( a disease found in domestic sheep), Bovine Sponfigorm Encephalitis (also referred to as "mad cow" disease) and Creutzfeld-Jakob disease (a TSE found in humans.) While similar to these diseases, there is no known causal link between CWD and other TSEs of animals or people. There is currently no evidence to indicate that CWD can be transmitted from elk and deer to livestock or humans.
Signs of an Infected Game Animal
Clinical signs of CWD include stumbling, poor body condition, excessive drinking and salivation and difficulty running. If you observe such signs, please report the sighting to your nearest NDOW office. Learn how you can help.
Sampling Efforts and Check Stations
CWD has not been detected in Nevada, yet sampling efforts in the state are ongoing. As of August 2004, the closest state to detect CWD in wild deer herds is Utah.
Nevada began routine testing for CWD in 1998. Through 2003, a total of 725 deer and 251 elk samples were tested and found negative for the disease. Samples were collected from a variety of methods, including contacts in field between NDOW biologists and hunters, check stations, road kills, and inspection at meat processing facilities. The majority of the samples came from hunter-harvested animals.
Biologists are keeping a close eye on population numbers and will continue to analyze samples by deer and elk game management units. In 2004, targeted mailings were sent to hunters with tags in management units where 
increased samples were needed by NDOW. Test results of deer and elk samples collected through December 2004 will be publicly available by April 2005.
How You Can Help
Your observations of animals showing possible signs of CWD are extremely valuable to NDOW biologists in the effort to monitor CWD status in Nevada. Clinical signs of CWD include stumbling, poor body condition, excessive drinking and salivation and difficulty running. If you observe such signs, please report the sighting to your nearest NDOW office or to the Operation Game Thief number listed below.
Hunters who would like to donate a sample from their deer or elk for Nevada’s CWD sampling effort may do so by bringing the head of the animal to one of the locations listed below during normal business hours. Hunters who are having taxidermy work done on trophy animals may not want to donate a sample since the process may damage the cape.
Carcass Disposal:
As a preventative measure in Nevada, if the deer or elk carcass is brought out of the field, the best practice to dispose of the carcass is to bury the head and spinal cord, or dispose of it an approved landfill closest to your location. Please see list of appproved landfills. If you harvest an animal in another state, please follow that state's CWD disposal guidelines.

Regulations :
Carcass Transportation Regulations in the United States and Canada
The number one objective in the management of CWD is to prevent its spread into new areas. One theoretical mode of disease transmission is via infected carcasses. Therefore, in an effort to minimize the risk of disease spread, a number of states have adopted regulations addressing the transportation of hunter-harvested deer and elk. It is important that resident hunters, as well as hunters traveling to other states are aware of the restrictions that apply to them.
Since the suspected infective agent (prion) is concentrated in the brain, spinal cord and lymph glands, the most common regulation is the prohibition of the importation of whole carcasses harvested from CWD areas. Some states, like Colorado, also have established regulations addressing the transport of deer and elk out of CWD areas. Generally, states that have adopted carcass transportation regulations do not allow the importation of any brain or spinal column tissue and allow transport of only the following:
- Meat that is cut and wrapped (either commercially or privately).
- Quarters or other portions of meat with no part of the spinal column or head attached.
- Meat that has been boned out.
- Hides with no heads attached.
- Clean (no meat or tissue attached) skull plates with antlers attached.
- Antlers with no meat or tissue attached.
- Upper canine teeth, also known as "buglers," "whistlers," or "ivories."
- Finished taxidermy.
Since these regulations are continually evolving, it is recommended that before hunting you check the CWD regulations in your home state, the state in which you will be hunting and states in which you will travel through en route home from your hunting area.
