Conservation > Wildlife Chronic Wasting Disease in Montana

CWD is a 100 percent fatal disease that infects members of the deer family, including elk, moose, mule deer, and white-tailed deer.

Hunting is the primary tool for monitoring and managing the spread of CWD. Concerns over CWD shouldn’t stop you from enjoying hunting season. Hunters are critical to conservation efforts across the state and protecting our wildlife heritage.

Carcass Disposal

Dumping carcasses is illegal, unethical and can spread diseases, including chronic wasting disease. Infected animals that are dead or alive can contribute to the spread of CWD. Scientists believe CWD prions likely spread between animals through body fluids like feces, saliva, blood, or urine, either through direct contact or indirectly through environmental contamination of soil, food or water.

All carcass parts, such as brain, eyes, spleen, lymph glands, and spinal cord material, should be bagged and disposed of in a landfill or may be left at the kill site.

Protect our herds: properly dispose of carcasses.
