As Autumn rolls onwards and the leaves begin to fall, hunters around the state begin to make their plans for the upcoming rifle hunting season commencing on November 23rd. Deer hunting, a conservation tool used for population management and DNR fundraising, has long been seen as a symbiotic relationship between hunters wanting to participate in outdoor recreation and state conservationists aiming to preserve the long-term viability of game populations. White-tailed deer are found throughout the state and are a hallmark of the Wisconsin landscape. Whether in your yard, at a park, or crossing the street, it seems deer sightings are a truly universal Midwestern experience. Unfortunately, a fatal disease called Chronic Wasting Disease (CWD) has been spreading across the state ever since its detection back in 2002. This challenge presents a new opportunity for conservationists and hunters to work together not only for game management, but to preserve the viability of the Wisconsin white-tailed deer population as a whole.
Chronic Wasting Disease: A Background
Chronic Wasting Disease (CWD) was first detected among captive deer in Colorado in 1967. It has since spread across 35 U.S states, including Wisconsin. CWD affects prion proteins, a type of protein commonly found in the brain, which then causes lesions in the brain, impairing neurological function in deer, elk, moose and caribou. This fatal disease can take well over a year to exhibit symptoms. Symptoms include: drooling, weight loss, drooping head and ears, lack of appetite, and little awareness of humans. Due to the way CWD affects deer, it’s been aptly nicknamed “zombie deer disease.” This debilitating disease can be transmitted by direct contact, saliva, urine, feces or by blood and excrement from dead carcasses. When excrement makes contact with the soil and foliage, it can stay in the environment for many years. CWD isn’t known to be transmissible to humans, but there are circulating theories regarding the effects of consuming infected venison, which the CDC advises against, therefore testing is recommended before consuming hunted venison.
Testing
Due to the fact that CWD is fatal and easily-transmissible, testing – especially during hunting season – is of the utmost importance. Testing during the hunting season is the easiest way to help conservationists discern where CWD is detected in the state, how many cases there are, and where it’s spreading. This means Wisconsin hunters are put on the frontlines of the DNR’s conservation efforts, as samples from their hunts give the DNR insights for future conservation efforts.
The Wisconsin DNR has testing stations in every county, with both self-service and staffed options being available. For example, Nature Net member site, the Upham Woods Outdoor Learning Center, is situated on the border of 4 CWD positive counties and has a new testing station for hunters in the area. Self-service kiosks allow hunters to drop off their deer head to be collected by DNR and later be sampled by the Wisconsin Veterinary Diagnostic Laboratory. Staffed testing stations will allow hunters to submit 100 grams of both muscle and liver tissue to be tested. If your deer tests positive for CWD, all is not lost, as not only are you avoiding a potential health risk through consumption, but you’ll receive a replacement tag that’s able to be used in the same county or statewide depending on if the deer is antlered or not. It cannot be stressed enough that cooperation between hunters and the DNR is essential for both parties, as testing is beneficial for all involved.

What You Can Do
Hunter or not, there’s always something you can do in regard to stopping and monitoring the spread. Firstly, do not touch, relocate, or eat meat from any roadkill or dead animals. Refrain from handling, shooting and eating animals that seem to look or act strange. It’s best to act with caution while further research can be done on CWD. Secondly, if you are a hunter, always wear rubber or latex gloves when handling or dressing hunted animals, and never use knives that you’d otherwise use in the kitchen. The DNR advises against relocating your deer from the county where it was hunted and to get your deer tested before eating. Finally, know the symptoms of CWD, and report any symptoms to the DNR. Whether you’re a hunter, a conservationist, or a lover of the outdoors, we all share a love for wildlife, so it’s our duty to work together to preserve the future of deer in the state.
