Can CWD Be Transmitted to Humans Through Hunting?

Understanding CWD

Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy (TSE) affecting deer, elk, and moose in North America. It is caused by a misfolded protein called a prion, which can be transmitted through direct contact with infected animal tissue or contaminated soil and water. Hunting and handling animals infected with CWD can increase the risk of exposure.

Transmission and Infection

The primary concern with CWD transmission to humans is through direct contact with infected animal tissue or contaminated materials. This can occur through cuts or scratches on the skin, or accidental ingestion of contaminated tissue. According to the CDC, handling and consuming venison from CWD-infected animals is not recommended, as the risk of transmission is unknown. If hunting in areas with CWD, hunters should wear protective gear, avoid handling infected animals, and follow proper handling and cooking procedures to minimize the risk of exposure.

Current Research and Recommendations

While there is no conclusive evidence of CWD transmission to humans through hunting, research is ongoing to determine the risks. The CDC recommends that hunters who harvest animals from areas with CWD report their harvest and allow for testing to determine if the animal is infected. Hunters should also take precautions when handling and processing venison, including wearing protective gear and following proper cooking procedures. In areas with CWD, hunters should also be aware of local regulations and guidelines for handling and disposing of infected animals.
