Wisconsin CWD Regulations 2027: What Deer Hunters Need to Know
Chronic wasting disease (CWD) continues to influence deer hunting regulations, wildlife management, and venison handling practices across Wisconsin.
For hunters planning the 2027 deer season, understanding CWD regulations is essential, particularly when it comes to county-specific baiting restrictions, deer carcass transportation, testing procedures, and proper disposal of potentially infected material.
Wisconsin has monitored chronic wasting disease in wild white-tailed deer since 1999, with the state's first positive cases identified in 2002.
Since then, the Wisconsin Department of Natural Resources (DNR) has expanded testing opportunities and implemented restrictions intended to reduce the spread of the disease.
However, not every Wisconsin county operates under the same baiting and feeding rules, and restrictions can change when additional positive deer are detected.
This guide explains what Wisconsin deer hunters need to know about CWD regulations for 2027, including how to check county restrictions, where to test harvested deer, how to transport carcasses, and what to do after receiving a positive results

What Is Chronic Wasting Disease in Wisconsin Deer?
Chronic wasting disease is a fatal neurological disease affecting members of the deer family, including white-tailed deer, elk, moose, and certain other cervids.
CWD belongs to a group of diseases caused by abnormal proteins known as prions.
Unlike diseases caused by bacteria or viruses, prion diseases involve misfolded proteins that damage nervous tissue.
In infected deer, CWD can produce progressive neurological deterioration.
Common Signs of CWD in Deer
Deer with advanced CWD may exhibit:
Significant weight loss
Poor body condition
Excessive salivation
Abnormal walking or coordination
Reduced awareness of surroundings
Unusual behavior
Increased drinking or urination
However, many infected deer appear healthy during earlier stages of infection.
A deer cannot be reliably identified as CWD-positive simply by looking at it.
Laboratory testing is necessary to confirm infection.
How Does CWD Spread?
CWD can spread through direct contact between infected and susceptible animals.
Infectious material may also enter the environment through saliva, urine, feces, and infected carcass tissues.
Because CWD prions can persist in the environment, disease management involves more than identifying visibly sick deer.
Reducing unnatural deer concentrations, testing harvested animals, and properly disposing of carcass waste are important parts of Wisconsin's management strategy.
Learn more through the Wisconsin DNR deer health resources.
Wisconsin CWD Baiting and Feeding Restrictions for 2027
One of the most important CWD-related regulations for Wisconsin deer hunters involves baiting and feeding restrictions.
Wisconsin does not apply a permanent statewide ban on all deer baiting.
Instead, restrictions are implemented on a county-by-county basis following qualifying disease detections.
Why Does Wisconsin Ban Deer Baiting in Certain Counties?
Baiting and feeding can concentrate deer in relatively small areas.
When multiple deer repeatedly visit the same feeding location, opportunities for direct and indirect disease transmission may increase.
Wisconsin uses baiting and feeding restrictions as one measure intended to reduce these risks.
How Long Do Wisconsin CWD Baiting Bans Last?
Under the state's established framework, a qualifying CWD detection can trigger:
Detection LocationGeneral Ban DurationCounty containing a qualifying positive detectionThree yearsAdjacent county within the applicable 10-mile detection areaTwo yearsAdditional qualifying detection during an existing banMay renew or extend the restriction
Bans can also result from qualifying bovine tuberculosis detections.
These periods are subject to applicable state rules and subsequent detections.
A county's restrictions can therefore change before or during a hunting season.
Wisconsin CWD Baiting Ban Map 2027
Hunters should not rely on a county list published several months before their hunt.
The DNR updates its baiting and feeding information as regulatory changes occur.
Before placing bait or feed, check the official Wisconsin DNR baiting and feeding restriction map.
This is particularly important for hunters traveling between counties.
A baiting practice that is legal in one county may be prohibited in a neighboring county.
Can You Bait Deer in Wisconsin in 2027?
Baiting may be permitted in counties without an applicable prohibition, but hunters must follow the state's restrictions on bait quantity, placement, timing, and materials.
Under current Wisconsin regulations, baiting is generally limited to two gallons per 40 acres on a qualifying parcel, with specific rules for parcels smaller than 40 acres.
Wisconsin Deer Baiting Quantity Rules
Property SizeGeneral Maximum Bait QuantityLess than 40 acresTwo gallons total40 acresTwo gallons total80 acresFour gallons total120 acresSix gallons total
These examples apply only where baiting is otherwise legal and remain subject to additional placement restrictions.
Bait Placement Restrictions
Current Wisconsin regulations prohibit certain bait placement practices, including placing bait too close to another bait site, public trails, roads, or campsites.
Hunters must also follow restrictions involving the amount of bait available near a hunting location.
Can You Use Food Plots in a CWD Baiting Ban County?
Normal agricultural practices and planted food plots are generally treated differently from deposited bait.
However, food plots cannot be established or maintained on DNR-owned or DNR-managed lands.
Hunters should distinguish between legally planted vegetation and material intentionally deposited to attract deer.
Are Deer Attractant Scents Legal?
Wisconsin generally permits scents used only to attract deer by odor, subject to restrictions on how they are placed and whether deer can consume them.
Hunters should review the exact scent rules before using liquid attractants or other products.
For the full requirements, consult the Wisconsin DNR deer hunting regulations.

Wisconsin CWD Testing Requirements for 2027
Wisconsin DNR currently offers voluntary CWD testing statewide.
Testing through the DNR is free for deer harvested in Wisconsin.
Although statewide testing is not mandatory, the DNR encourages hunters to submit samples.
Testing helps identify infected animals and improves understanding of disease distribution.
Is CWD Testing Mandatory in Wisconsin?
No. Under the currently published statewide rules, CWD testing is not mandatory for every harvested deer.
However, hunters should distinguish voluntary CWD testing from mandatory deer harvest registration.
These are separate processes.
A hunter must register a harvested deer even if they do not submit it for CWD testing.
How Much Does Wisconsin CWD Testing Cost?
DNR testing is free for deer harvested in Wisconsin.
Hunters may also have access to certain private or third-party testing services that charge fees.
How Long Do Wisconsin CWD Test Results Take?
Wisconsin DNR generally reports that results are available approximately 10–14 days after the sample reaches a testing location.
Turnaround times can vary based on testing volume and available resources.
Hunters should plan accordingly if they intend to wait for test results before consuming venison.
Find current information through the Wisconsin DNR CWD sampling page.
How to Get a Deer Tested for CWD in Wisconsin
Wisconsin offers several ways to submit a harvested deer for CWD testing.
Hunters can choose the method that works best for their location and schedule.
Option 1: Self-Service CWD Testing Kiosks
Wisconsin operates self-service sampling kiosks at participating locations.
Many kiosks are accessible 24 hours a day.
Hunters generally submit the deer head with approximately five inches of neck attached.
The DNR provides instructions for preparing and submitting samples.
Option 2: Participating Meat Processors and Taxidermists
Some cooperating businesses assist hunters with CWD sample collection.
This can be particularly convenient for hunters who plan to have a deer professionally processed or mounted.
Contact the business before arriving to confirm that it participates in the program.
Option 3: At-Home Lymph Node Collection
Wisconsin offers an option for hunters to collect the appropriate lymph node samples themselves.
Hunters should use the DNR's instructions and required sampling materials.
This option can be useful for hunters who want to preserve the deer head or minimize transportation.
Option 4: Appointment With DNR Staff
Hunters may arrange sample collection assistance with DNR personnel where available.
This option may be particularly useful when coordinating a European mount or other taxidermy work.
Steps to Submit a CWD Sample
Register the harvested deer through Wisconsin GameReg.
Locate a participating CWD sampling site.
Prepare the deer head or approved sample.
Complete the required sample information.
Submit the sample following the location's instructions.
Monitor the testing results through the DNR's available systems.
The DNR provides an interactive CWD sampling and disposal location resource.
Wisconsin Deer Harvest Registration vs. CWD Testing
Harvest registration and CWD testing are different requirements.
Under current Wisconsin rules, harvested deer must be registered by 5 p.m. the day after the carcass is recovered.
Hunters can register through Wisconsin GameReg.
CWD testing is a separate voluntary process.
RequirementMandatory?Valid deer hunting license and authorizationYesCompliance with season and harvest rulesYesDeer harvest registrationYesStatewide CWD testingNoCompliance with applicable baiting bansYesCompliance with applicable carcass transport rulesYes
Hunters should not assume that submitting a deer for CWD testing automatically completes harvest registration.
Review Wisconsin DNR deer hunting requirements.
Wisconsin Deer Carcass Transportation Rules for 2027
Carcass transportation is an important part of CWD management.
Moving infected carcasses or high-risk tissues into new areas can contribute to the spread of infectious material.
Wisconsin DNR recommends limiting the transportation of whole deer carcasses outside the county of harvest or an adjacent county.
Hunters should distinguish this recommendation from legally enforceable restrictions that apply to certain carcasses entering Wisconsin from other jurisdictions.
Can You Transport a Deer Between Wisconsin Counties?
Wisconsin DNR recommends minimizing the movement of whole carcasses beyond the county of harvest or an adjacent county.
Hunters should follow current transportation rules and choose processing or disposal options that reduce the movement of potentially infected tissues.
Bringing Deer Carcasses Into Wisconsin From Other States
Wisconsin restricts the importation of whole cervid carcasses and certain carcass parts from states or provinces where CWD has been detected.
Certain exceptions apply, including transportation to a licensed meat processor or permitted taxidermist within the required timeframe.
Hunters should verify the current restrictions before returning to Wisconsin with a deer harvested elsewhere.
Taking a Wisconsin Deer Into Another State
Hunters traveling home from Wisconsin must also follow the carcass importation rules of their destination state.
Some states prohibit importing whole deer carcasses from CWD-affected jurisdictions.
Rules can differ for boned-out meat, cleaned skull plates, finished taxidermy, and other materials.
Before traveling, check the regulations for every applicable state.

How to Properly Dispose of Deer Carcass Waste in Wisconsin
Proper disposal helps reduce the possibility of CWD-contaminated material being introduced into new areas.
Wisconsin DNR recommends disposal methods that place deer carcass waste in appropriately managed landfills whenever practical.
Recommended Deer Carcass Disposal Options
Hunters may be able to use:
Designated deer carcass disposal dumpsters
Landfills that accept deer carcass waste
Participating transfer stations
Approved municipal waste collection services
Other disposal methods permitted by applicable rules
Not every landfill or transfer station accepts deer carcasses.
Hunters should contact the facility before transporting waste.
Can You Leave Deer Bones and Carcass Waste in the Woods?
Hunters should avoid moving potentially infectious carcass material into new locations.
Wisconsin regulations permit certain nonedible deer parts to be left in the field during lawful quartering.
However, proper waste handling remains important.
Where practical, use DNR-recommended disposal options rather than dumping carcass waste in waterways, roadside ditches, or other inappropriate locations.
Find current facilities through the Wisconsin DNR deer waste disposal resource.
Is It Safe to Eat Venison From a Deer With CWD?
Wisconsin DNR, the Wisconsin Department of Health Services, and the Centers for Disease Control and Prevention recommend that hunters do not eat meat from deer that test positive for CWD.
There have been no confirmed human cases of CWD, but scientific uncertainty remains about potential risks from exposure to infected animals.
The absence of confirmed human cases should not be interpreted as proof that consuming infected meat is safe.
Should You Wait for CWD Test Results Before Eating Venison?
Hunters who submit deer for testing should consider keeping the meat separate and waiting for results before consuming it.
This is particularly important when hunting in areas with known CWD detections.
Does Cooking Kill CWD Prions?
Normal cooking temperatures are not considered a reliable method for eliminating CWD prions.
Cooking, freezing, smoking, or other ordinary food preparation methods should not be relied upon to make meat from a CWD-positive deer safe.
How Should Hunters Handle Harvested Deer?
Hunters should use appropriate field-dressing precautions, avoid unnecessary contact with brain and spinal tissues, and clean tools and work surfaces according to applicable public health guidance.
If a deer tests positive, follow DNR and public health recommendations for handling and disposal.
What Happens if Your Wisconsin Deer Tests Positive for CWD?
Wisconsin currently offers replacement harvest authorizations to eligible hunters whose harvested deer test positive for CWD.
The replacement authorization depends on the original harvest authorization.
Under the DNR's September 2026 guidance:
Original HarvestReplacement AuthorizationAntlered deerReplacement antlered authorization, valid statewideAntlerless deerEither-sex replacement authorization for the same deer management unit and land type
The DNR states that replacement authorizations are not weapon-specific and may remain valid through the current season and the following year's hunting seasons, subject to the program's rules.
Hunters should check their Go Wild account and follow the instructions provided with the positive result.
A positive result does not mean hunters should retain or consume the infected meat.
Review the Wisconsin DNR's September 2026 deer herd health update.
Wisconsin CWD Statistics and Disease Monitoring
Wisconsin continues to monitor CWD through hunter-submitted samples and targeted surveillance efforts.
According to Wisconsin DNR's March 2026 summary of the 2025 hunting season:
2025 Surveillance MetricReported ResultDeer sampled statewide17,759CWD-positive samples2,006CWD sampling locations242Self-service kiosks163
These figures represent deer submitted for testing, not a random sample of Wisconsin's entire deer population.
The percentage of submitted samples testing positive should not be treated as the statewide infection rate.
Sampling intensity and hunter participation can differ significantly between counties.
Read the Wisconsin DNR's 2025 CWD sampling summary.
Wisconsin CWD Regulations by County
Wisconsin's CWD management system requires hunters to pay attention to county-level restrictions.
A county may have a baiting and feeding prohibition because of a qualifying CWD detection within the county or a nearby area.
Restrictions can be extended when additional cases are identified.
How to Check Your County Before Hunting
Before hunting in 2027:
Identify the county where you plan to hunt.
Open the official Wisconsin DNR baiting and feeding map.
Confirm whether baiting or feeding is prohibited.
Review the current deer hunting regulations.
Identify nearby CWD testing locations.
Locate an appropriate carcass disposal facility.
Recheck restrictions shortly before your hunt.
A county's status should not be assumed to remain unchanged from the previous hunting season.

Wisconsin Antlerless Deer Tags 2027: Permits, Zones & Availability
Wisconsin uses antlerless deer harvest authorizations rather than a traditional statewide doe-tag lottery. Hunters receive certain authorizations with qualifying deer licenses, while additional bonus antlerless authorizations are sold on a first-come, first-served basis. The state has four primary deer management zones: Northern Forest, Central Forest, Central Farmland, and Southern Farmland. Most antlerless authorizations are restricted to a designated DMU and land type. For 2026, Wisconsin approved 272,720 bonus antlerless authorizations statewide, separate from Farmland authorizations issued with deer licenses. The 2026 bonus sale began August 17, with separate opening dates by zone. Current bonus authorization prices are $12 for residents, $20 for nonresidents, and $5 for hunters under age 12. The final 2027 permit allocations, sale dates, and remaining inventory are not yet confirmed. Hunters should use 2026 information for planning and check the Wisconsin DNR before purchasing.

Wisconsin Deer Rut Forecast 2027: Best Dates to Hunt Mature Bucks
The best time to hunt the Wisconsin deer rut in 2027 will likely be from late October through mid-November, with November 4–8 standing out as a particularly promising period for mature buck movement. Wisconsin Department of Natural Resources research found that GPS-collared bucks in southwestern Wisconsin consistently reached peak movement during November 4–8 across four consecutive years. Additional research places the broader rut activity window between approximately October 23 and November 12. For hunters scheduling vacation, October 30–November 12 is an excellent planning window. November 4–8 is particularly attractive for hunters targeting mature bucks during daylight hours. The rut is primarily driven by changing day length, meaning the general timing remains relatively consistent from year to year. Cold fronts, wind, precipitation, and hunting pressure can influence when and where hunters observe deer, but they do not reliably shift the biological breeding season. Hunters should prioritize bedding-area travel corridors, doe concentrations, terrain funnels, and all-day sits during periods of increased buck movement. These are research-based planning windows, not guaranteed daily movement forecasts. The final 2027 Wisconsin deer hunting season dates must also be confirmed through the Wisconsin Department of Natural Resources.

Guided Mountain Goat Hunts 2027: Outfitters & Costs
Guided mountain goat hunts offer access to some of North America's most spectacular and challenging alpine hunting environments. For 2027, hunters should focus on five key considerations: destination, license availability, outfitter quality, physical difficulty, and total hunt cost. Alaska: Offers guided mountain goat hunting opportunities in designated areas, with some hunts requiring drawing permits or registration. British Columbia: One of the most established destinations for guided nonresident mountain goat hunting. Yukon: Provides remote mountain goat opportunities through authorized outfitting arrangements, subject to current regulations and territory availability. Washington and other Lower 48 states: Generally require extremely competitive limited-entry permits before a guided hunt can take place. Estimated hunt costs: Approximately $12,000–$30,000 or more for a guided hunt, depending on location, duration, transportation, and services. Licensing: A guide booking does not automatically guarantee a mountain goat tag. Physical demands: Mountain goat hunting often involves steep terrain, difficult footing, variable weather, and challenging meat recovery. 2027 availability: Hunters should confirm hunt dates, prices, licenses, quotas, and outfitter credentials directly before paying a deposit. The right guided hunt depends on the hunter's goals, fitness, budget, and willingness to travel into remote mountain country.
