Common Misconceptions About CWD — What’s True?

Chronic wasting disease (CWD) is often misunderstood, with many hunters and hunters’ organizations perpetuating false information. Two common misconceptions are that CWD can only be transmitted through direct contact with an infected animal, and that it’s a relatively new disease. In reality, CWD has been present in some areas for decades.

Transmission and Spread of CWD

CWD is a prion disease that can be transmitted through direct contact with an infected animal’s tissues, as well as through environmental contamination. Infected deer can shed prions in their saliva, urine, and feces, which can then be ingested by other animals or contaminate the environment. Studies have shown that CWD prions can persist in the environment for up to 10 years, making it difficult to eradicate the disease once it’s established.

Risk Factors and Prevention

Hunters can take several steps to minimize their risk of contracting CWD. These include wearing gloves when handling deer and using disinfectant on equipment and clothing, as well as avoiding eating meat from deer that appear sick or have visible lesions. It’s also essential to report any deer that appear sick or act strangely to local wildlife authorities. In areas where CWD is present, hunters should consider having their deer tested for the disease before consuming the meat.

Testing and Management

Testing for CWD is a crucial step in managing the disease. The most common method is to collect a sample from the deer’s brain stem or lymph nodes, which can be done by a qualified professional or a hunter with proper training. In areas where CWD is present, hunters may be required to have their deer tested before consuming the meat. The results of CWD testing can be used to inform management decisions, such as culling infected animals and implementing restrictions on deer feeding and baiting.
