Chronic Wasting Disease (CWD) has been reported in a hunter-harvested white-tailed buck in Concordia Parish, the Louisiana Department of Wildlife and Fisheries (LDWF) said. The buck was harvested on Richard K. Yancey Wildlife Management Area (WMA) and is the first CWD detection in a wild deer in Concordia Parish. 

CWD was first detected in Louisiana in 2022. The latest positive brings the total number of CWD detections for Louisiana to 44.

Initial diagnostics by the Louisiana Animal Disease Diagnostic Laboratory (LADDL) detected CWD prion in tissue samples submitted by LDWF. Per required protocol, LADDL has forwarded the sample to the National Veterinary Services Laboratory (NVSL) in Ames, Iowa for confirmatory testing. Final confirmation is anticipated in the coming weeks. 

Due to this preliminary detection during the ongoing deer season, hunters are encouraged to submit additional hunter-harvest samples for testing. A CWD sample drop-off site is located along Highway 15 near the northern boundary of Richard K. Yancey WMA.

To obtain viable samples for testing, a fresh head including a few inches of neck is required. Data submission cards and bags are available on site. Once completed, the bagged deer head and data card should be placed in the available cooler at the CWD drop-off site.

LDWF is currently in the process of implementing the LDWF CWD response plan. More information regarding the response plan and intended mitigation efforts for this area will be forthcoming.

“We continue to count on our hunters, property owners, deer processors and taxidermists for their assistance in monitoring CWD as their continued partnership with our department will help manage the expanse of CWD in the state keeping our deer population healthy,’’ LDWF Secretary Tyler Bosworth said.

CWD is a neurodegenerative disease of white-tailed deer and other members of the Cervidae family. The disease is caused by a prion, an infectious, misfolded protein particle, and is 100-percent fatal in affected deer after an indeterminate incubation period. There is no treatment or preventative vaccine for CWD. CWD-infected deer may exhibit symptoms of weight loss and emaciation, salivation, frequent drinking and urination, incoordination, circling, lack of human fear, and subsequent death of the animal.

Although CWD has not been shown to be contagious to humans, the Centers for Disease Control and the World Health Organization recommend against the human consumption of deer known to be infected with CWD. Also, it is recommended that people hunting in areas known to harbor CWD-infected deer have their deer tested for the disease prior to consumption. LDWF provides CWD testing for hunter-harvested deer free of charge.
