Ohio Division of Wildlife Acts to Curb Chronic Wasting Disease Amidst Hunting Season Launch
COLUMBUS, Ohio — As hunting season begins in Ohio, officials from the Ohio Division of Wildlife are intensifying efforts to limit the spread of Chronic Wasting Disease (CWD), a fatal neurological condition affecting deer populations in central Ohio.
Lindsey Krusling, a wildlife specialist with the Ohio Division of Wildlife, emphasized the importance of controlling CWD to protect local deer herds, noting its potential to cause population declines over time.
“We observe population decreases when CWD becomes established, and its spread can threaten adjacent herds,” Krusling stated. “Because the disease’s prevalence escalates gradually, our goal is to slow this progression to preserve healthy deer populations.”
Confirmed Cases and Disease Characteristics
The Ohio Department of Natural Resources reports that over 70 wild deer across multiple counties have tested positive for CWD. The disease, caused by abnormal prion proteins, systematically deteriorates nervous tissue, particularly in the brain.
Biologically, prions induce spongiform changes in neural tissue, impairing motor functions and behavior, which explains symptoms such as loss of coordination and diminished fear of humans. The condition is invariably lethal for infected animals.
Transmission and Wildlife Management Measures
Transmission occurs via direct contact between animals or indirectly through contaminated environmental materials. This aspect complicates containment in wild populations, making early intervention critical.
To reduce transmission risks, new hunting regulations prohibit baiting and feeding of deer and restrict transportation of whole carcasses in designated areas. These restrictions aim to minimize artificial congregation and movement of potentially contaminated materials.
Targeted Hunting and Surveillance Efforts
Additional measures include extended hunting opportunities within designated disease surveillance zones, particularly focusing on adult male deer, which are more likely to be infected and facilitate transmission.
“Removing mature males early helps reduce disease spread since younger deer generally have lower infection rates,” Krusling explained.
Testing Mandates and Hunter Guidance
The Division of Wildlife will enforce mandatory testing periods in October and December to monitor disease prevalence actively. Hunters are strongly encouraged to submit samples from harvested deer for CWD testing, with authorities advising against consumption of animals that test positive.
