The Louisiana Animal Disease Diagnostic Laboratory (LADDL) has reported the first suspected case of chronic wasting disease (CWD) for the 2022-23 hunting season to the Louisiana Department of Wildlife and Fisheries (LDWF).
LADDL has submitted the suspect sample to the National Veterinary Services Laboratory in Ames, Iowa for confirmatory testing. If confirmed, this would be the second case of CWD detected in Louisiana.
The presumptive positive was made on samples submitted by LDWF staff from a hunter-harvested adult buck taken on private land in Tensas Parish. While this is the first suspect positive case of CWD in the 2022-23 hunting season, a positive was confirmed in the same parish on Jan. 28, 2022. Tensas Parish has been an area of heightened surveillance for CWD by LDWF since a case of CWD was found in Issaquena County, Mississippi, in 2018.
The Louisiana Wildlife and Fisheries Commission has adopted regulations for the Chronic Wasting Disease (CWD) Control Area in northeast Louisiana. The current CWD Control Area includes all of Tensas Parish and portions of Madison and Franklin parishes. To learn more about CWD and complete regulations, go to: https://www.wlf.louisiana.gov/
CWD is a neurodegenerative disease of white-tailed deer and other members of the family Cervidae. It 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 signs of weight loss and emaciation, salivation, frequent drinking and urination, incoordination, circling, and lack of fear of people, and always results in 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 consuming the animals. LDWF will provide testing for hunter-harvested deer free of charge.
Hunters desiring to have their harvested deer tested for CWD should contact local LDWF Field Offices to have their deer tested. In addition, seven CWD sample drop off locations are located within the CWD Control Area. Testing is performed on the brainstem and lymph nodes of the head. The head and five inches or more of the neck can be removed and refrigerated for submission to LDWF. The skull plate and antlers can be removed prior to testing if desired.
