2022 Cervid Import & Chronic Wasting Disease (CWD) Info

Oklahoma deer hunters may have heard about Chronic Wasting Disease (CWD) afflicting deer and elk in other states. The Wildlife Department has been following the progress of CWD for decades and is making preparations in case the disease is detected in the state's wild herd.

CWD is a neurological disease that affects the brains of deer, elk, moose, and other members of the deer family, creating holes that resemble those in sponges. It is always fatal to the animal, and no treatment or vaccine against CWD exists at this time. CWD has been confirmed in wild deer and elk in surrounding states including Texas, New Mexico, Colorado, Kansas, Missouri, and Arkansas.

No case of CWD has ever been confirmed in a free-ranging wild deer or elk in Oklahoma. In 1998, CWD was confirmed in a captive elk herd in Oklahoma County which had originally been imported from Montana. The U.S. Department of Agriculture euthanized that herd to decrease the threat of the disease spreading into the surrounding free ranging deer herd. Subsequent testing outside of the enclosure did not locate any positive animals. In April 2019, CWD was confirmed in one farmed Oklahoma elk in Lincoln County. ODWC announced it would step-up surveillance in areas adjacent to the breeding facility. In 2022, the Wildlife Department was notified by the Texas Parks & Wildlife Department (TPWD) of a road-killed deer infected with chronic wasting disease (CWD) found 2.5 miles south of the Oklahoma-Texas border near Felt, Okla., in southwestern Cimarron County. With the proximity of this infected deer to Oklahoma's border, ODWC activated its CWD Response Plan. This includes the designation of a Selective Surveillance Area (SSA).

ODWC takes disease issues very seriously because of the potential effects to the state’s rich hunting traditions, human health concerns, the risk to natural resources, and the $1.2 billion impact hunting has on our state's economy annually. ODWC’s primary objective is to minimize the risk to Oklahoma's wild deer, elk, and other susceptible cervids within our borders.  

ODWC is reviewing and updating its response plan in response to new scientific research and the disease's closer proximity to our state. ODWC is also coordinating with the Oklahoma Department of Agriculture, Food and Forestry and other agencies to monitor the state’s captive cervid herds and provide information to the public as it becomes available.

ODWC has conducted CWD monitoring on hunter-harvested deer and road-killed deer and elk since 1999. CWD was not detected in laboratory testing of tissue samples from more than 10,000 wild deer and elk from throughout Oklahoma.
