Are there any specific diseases affecting Oklahoma deer herds?

April 5, 2026

Quick Answer

Deer in Oklahoma are affected by chronic wasting disease (CWD), a neurological disorder that impacts deer populations nationwide. CWD has been detected in western and central Oklahoma. It is essential to follow proper handling and disposal procedures for deer carcasses to minimize the risk of disease transmission.

Understanding Chronic Wasting Disease in Oklahoma Deer

Chronic wasting disease (CWD) is a progressive, fatal neurological disorder affecting deer and other cervids. It is caused by misfolded proteins (prions) that are transmitted through direct contact with infected deer or contaminated environments. CWD has been detected in multiple Oklahoma counties, primarily in areas with high deer densities.

Identifying and Reporting CWD-Positive Deer

If you harvest a deer in an area with known CWD cases, it is crucial to have it tested for the disease. The Oklahoma Department of Wildlife Conservation (ODWC) offers free CWD testing for deer harvested within the state. To participate, submit a deer sample from the following locations: the base of the skull, the brain stem, or the lymph nodes. Ensure proper handling and packaging of the sample to prevent contamination.

Best Practices for CWD Prevention and Control

To minimize the risk of CWD transmission, follow these best practices when handling and disposing of deer carcasses: wear disposable gloves and protective clothing, use a sharp knife to prevent tearing the flesh, and dispose of the carcass in a designated landfill. Avoid feeding wild deer, as this can concentrate deer populations and increase the risk of disease transmission. Always check with local authorities for specific regulations on deer carcass disposal in your area.
