Updated on September 7, 2026. This is a hunter how-to, not a diagnosis. Confirm drop-off sites, mandatory units, and carcass rules on your state wildlife agency page before you leave camp. Dates and counties below were last checked against the linked agency pages on this date.
To get a deer tested for CWD, submit the head (with several inches of neck) or the extracted retropharyngeal lymph nodes through the channel your state actually runs: a staffed check station, a 24-hour kiosk or drop freezer, a cooperating processor or taxidermist, or a USDA-approved lab. Testing is free in most surveillance programs. Results usually post online in days to a few weeks. The CDC still reports no human CWD cases, and still tells hunters in known CWD country to test the animal and not eat meat from a deer that tests positive.
This page is the testing how-to. The safety hub is the table of contents. What a sick deer looks like lives on CWD symptoms. What the steaks look like (they look like steaks) lives on what CWD looks like in deer meat. “Zombie deer” search language is a separate child. This page does not swallow those answers.

Those numbers wear the hrefs in the table. A county that was “clean” last November can be a new detection this October. Do not hunt off a screenshot of last year’s map.
Why you cannot eyeball it
Chronic wasting disease is a fatal prion disease of white-tailed deer, mule deer, elk, and moose. The stumbling, drooling, hip-bone deer in the photos is end-stage. Most hunter-harvested positives look and act normal. The meat looks normal. That is the whole point of the lab: symptoms and the steaks are not a screen.
Two other diseases get mixed into the same “sick deer” phone call. EHD drops deer in late summer around water; CWD does not. The disease hub at deer diseases is the index. This page is only the sample, the drop-off, and the result.
Your sample is also how agencies map the disease. Wisconsin’s 2024 hunting-year haul — 17,399 deer, 1,786 positive, most of those in the Southern Farmland Zone — exists because hunters put heads in kiosks. The DNR’s 2024 sampling summary is the receipt.
Three questions before opening weekend
Open your state CWD page, not a forum thread, and answer these for the exact county or unit you will hunt:
- Mandatory or voluntary? Idaho’s 2026 list is a unit list. Michigan’s 2026 focused counties are a county list. Wisconsin is voluntary and statewide. Pennsylvania’s free bins sit where CWD has already been found in the wild.
- Where does the head go, and when? Staffed stations keep hours. Kiosks and freezers do not. Processors and taxidermists only help if they are on this year’s cooperator list.
- What can leave the zone? Many states let boned-out meat, a cleaned cape, and a cleaned skull plate travel, and stop a whole head or spine at the line. If you hunt Wisconsin and drive home to Illinois, or hunt Pennsylvania and live outside the WMU, read both sides of the state line.
The public map of detections is the USGS June 2026 distribution map. State pages overlay the drop boxes. Use both.
The four ways a sample actually gets to a lab
| Route | What you do | Where it is the default |
|---|---|---|
| Staffed station | Bring the deer or head during posted hours. Staff pull the nodes. | Opening weekend, mandatory units, Michigan focused counties, Wisconsin staffed sites. |
| Self-serve kiosk or freezer | Bag the head, fill the form or scan the QR, leave it. | Wisconsin 24/7 kiosks. Michigan DNR drop boxes. Pennsylvania head bins. |
| Cooperating processor or taxidermist | They pull nodes while they cape or cut. | Useful for a shoulder mount. In Pennsylvania, taking a deer to a processor is not a guarantee it will be tested — the bin is. |
| Mail-in / self-extract | You pull the retropharyngeal nodes and ship them to a NAHLN lab. | Michigan free kits outside focused counties. Wisconsin kiosk sample packets. Idaho lymph-node option so the head can stay in the field. |
There is no reliable drugstore “CWD stick” for a hunter. USDA’s official assays for this disease are ELISA and IHC run at approved labs. If a kit is not on that APHIS list, it is not the result your agency will post.
What the sampler is reaching for
The two validated ELISA tissues are the medial retropharyngeal lymph nodes — a pair of nodes deep in the throat, behind the angle of the jaw — and the obex of the brainstem. That is why a “head” submission is not a skull-cap. Leave neck on the head so the person at the kiosk, or you at the kitchen table with a printed poster, can find the nodes without guessing at fat and salivary glands.
- Wisconsin is specific: head with 5 inches of neck. Refrigerate at 35–45°F for up to five days, or freeze if it will sit longer. Register the deer in GameReg before you fill the CWD form — they are different numbers. Source: WI DNR sampling page.
- Pennsylvania: double-bag the head, completed harvest tag physically attached to the ear, then into the bin. Antlers and skulls are not returned. Pull the rack first. Bin map: arcg.is/1G4TLr. Instructions in the 2025–26 Hunt/Trap Digest.
- Michigan: complete a harvest report before you submit. Focused 2026 counties take whole heads at drop boxes and staffed sites; those heads are also screened for bovine tuberculosis. Outside those counties, the free path is a lymph-node shipping kit to Michigan State University’s Veterinary Diagnostic Laboratory. Do not extract nodes from deer taken in Alcona, Alpena, Cheboygan, Crawford, Iosco, Montmorency, Ogemaw, Oscoda, Otsego, Presque Isle, or Roscommon — those are the bovine-TB counties. Take the whole head to a DNR field office. Source: Michigan CWD testing.
- Idaho 2026: head or lymph nodes within 10 days. If you pull the nodes yourself, the rest of the head stays in the field. Whole carcasses do not leave a CWD Management Zone except as the proclamation allows. Source: IDFG, 2026 CWD requirements.
If you want a shoulder mount, cape first. The nodes come from what is left. Walk that sequence on how to cape a buck rather than guessing at a kiosk with a knife in the dark. Photograph the sample barcode, the harvest tag, and the confirmation number. That string is how you get the result, not your last name.
How three busy states actually run this
Wisconsin: kiosks, then a barcode
The DNR’s own page lists four routes: 24/7 self-service kiosks, cooperating processors and taxidermists, at-home node extraction with a kiosk packet, and by-appointment staff. Testing through the DNR is free for a Wisconsin-harvested deer. In an average year the result posts in 10–14 days at the CWD test results page (barcode or customer ID). A CWD-positive hunter gets a replacement harvest authorization on the Go Wild account, typically two to four days after notification.
If you hunt the north woods instead of the southern farmland, prevalence is not the same animal. That is the honest split on Wisconsin vs Michigan public land and on the Wisconsin hunting guide: you still test, because a new county detection is how the map moves.
Michigan: 2026 is a county list, not “the whole LP”
For 2026 the DNR is running focused free head collection in Ionia, Kent, Mecosta, Montcalm, and Newaygo. Find the box on the deer stations and disease-sample page. Everyone else in the state, outside the bovine-TB block, can pick up a free overnight lymph-node kit. Results from DNR boxes post on the DNR lab page. Results from MSU VDL email to the hunter and do not appear on the DNR lookup. Those are two different inboxes. Do not call the DNR about an MSU number.
The 2025 focused-surveillance table, current as of March 19, 2026 on the 2025 CWD testing results page, showed 1,467 deer with final results and 6 positives in that DNR dataset. That is a surveillance slice, not the lifetime count, and it is why Michigan still asks for heads. Hunt logistics for the state sit on Michigan deer hunting.
Pennsylvania: the bin is the test
The Game Commission’s own FAQ on the results lookup is blunt: a processor deer is not guaranteed a test. Random processor samples happen. A head in a commission bin is the way to make sure. Enter hunting-license CID and date of birth. A “Detected” result means prions were found. Call 1-833-463-6293. Hunters who harvest a CWD-positive deer or elk are eligible for a replacement tag. Results are commonly two to three weeks in the current digest; older DMA pages said up to six weeks when the lab is slammed. If nothing has posted, use the hotline, not a Facebook group.
Meat while you wait
You will usually have the deer in bags before the lab posts. That is fine if you cut it like the CDC page reads.
- Gloves. Latex or nitrile for field dressing and butchering. The habit belongs on how to field dress a deer even in a CWD-free county.
- Bone it out. Skip splitting the spine. Leave brain, spinal cord, spleen, and lymph nodes out of the kitchen. Quartering is on how to quarter a deer; the full cut list is on the processing guide.
- Do not use the kitchen knives. That is CDC language, not a blogger preference. Prions are not a bacterium you boil off a chef’s knife.
- One deer, labeled. If a commercial shop batches grind from several hunters, a later positive on someone else’s deer makes your packages a paperwork problem. Ask for individual processing.
- Freeze and wait if you hunted where CWD is established. Venison does not mind a couple of weeks in the freezer. Hold times are on how long venison keeps. In a county with no detections, many hunters eat while the result is pending. The CDC line that does not move: if it comes back positive, do not eat it.
The rest of the after-the-shot sequence — tracking, gutting, hanging — is the after-the-shot hub and what to do after you shoot a deer. CWD sampling is one box on that list, not a replacement for it.
If the result is positive
Do not eat the meat. Cooking, freezing, smoking, and curing do not destroy prions. Heat that would matter would incinerate the roast. That is why the test, not the recipe, is the control. The venison cooking guide is for a negative deer.
Call the agency. Most want the carcass and trim in a landfill, not dumped on a logging road. Wisconsin’s carcass-handling page is the model: bag it, landfill it, do not leave the head or spine on the landscape. Ask about a replacement tag. Agencies want the positive reported, not quietly eaten and forgotten.
A negative result, which is still the usual result even in established zones, clears that deer for the table. It does not clear the next deer. Test that one too.
Carcasses across a line
High-risk parts are some version of head (brain, eyes, tonsils, lymph nodes), spinal column, and spleen. A cleaned skull plate, a finished mount, boned meat, and a cape without obvious brain or spinal tissue are the usual exceptions — if your two states say so this year. Pennsylvania’s digest still treats import of high-risk parts from other CWD jurisdictions as a cooperator-only move. Idaho’s 2026 note is the same idea in the other direction: whole carcasses stay in the CWD Management Zone. Read the current proclamation. Do not copy a 2023 forum post.
Frequently asked questions
Can you eat the deer before the CWD result posts?
In known CWD country, freeze it labeled and wait. That matches CDC language to test before you eat. In a county with no detections where you tested only as a favor to the survey, many hunters eat during the wait. Once a deer is positive, do not eat what is left in the freezer.
How long do results take?
Wisconsin’s published average-year window is 10–14 days. Pennsylvania’s current digest is about two to three weeks. Opening week of gun season is slower everywhere. If the posted window has passed, call with the sample ID or CID, not with “the eight-point from the oak ridge.”
Is CWD in people?
CDC’s January 21, 2026 page: no reported human cases, and it is not known whether people can be infected. The caution exists because another animal prion disease (BSE) did jump, and because some monkey-feeding studies were not clean. Testing plus not eating positives is the hedge they ask hunters to take. This page is not a medical opinion.
Does a home test or a “quick kit” count?
Not for the official result. USDA-approved hunter diagnosis is ELISA and/or IHC at a NAHLN lab. RT-QuIC is used in research. If you mail nodes, mail them to a lab on the APHIS list, packed how that lab says, usually overnight on ice Monday–Wednesday.
What if the sample comes back unsuitable?
Decomposed, dried-out, or the wrong lump of tissue. Wisconsin and Michigan both warn that a bad sample helps no one. Keep the head cold, get it in within a few days or freeze it, and if you self-extract, use the agency poster — the nodes are not the obvious glands under the jaw.
