Illinois CWD Testing and Deer Carcass Rules
Illinois testing is free and voluntary statewide, but a deer killed during a firearm season in one of the eighteen CWD surveillance counties must go to a designated check station the same day, and no whole deer or elk carcass from any other state may be brought in.
Is CWD testing required in Illinois
Illinois has found the disease in wild deer, and Illinois Department of Natural Resources sets no requirement to submit a sample. A test is offered on any deer a hunter brings in.
- How to submit
- Illinois Department of Natural Resources names CWD sample drop-off barrels, sampling vendors, IDNR cooperating taxidermist, mail-in sampling kits requested online and designated firearm deer check station in a CWD surveillance county.
- What it costs
- Illinois Department of Natural Resources puts the test at no charge to the hunter.
- The zone it draws
- counties with CWD surveillance
Hunters are strongly encouraged to test their deer for free.Chronic Wasting Disease Sampling, Hunt Illinois, Illinois Department of Natural Resources, read September 23, 2026. Read it at the source
What may be carried across the Illinois line
This is the rule a hunter is most likely to miss, because it is written by the state being entered rather than the state the animal was taken in. Reading the regulations of the state hunted in cover to cover does not surface it. Nationally, 42 of the 50 states restrict what crosses and 27 refuse an intact carcass from anywhere at all.
An intact carcass may not be carried into Illinois from any other state. The parts IDNR does admit are listed below.
No hunter harvested deer or elk carcass may be brought into Illinois from anywhere; only deboned meat, antlers, antlers on a cleaned skull cap, hides, upper canine teeth and finished taxidermy mounts may cross the line, with a 72 hour exception for a carcass delivered straight to a licensed Illinois processor or taxidermist.
What IDNR admits, in its own categories:
- deboned meat
- antlers
- antlers attached to skull caps
- hides
- upper canine teeth (also known as “buglers,” “whistlers,” or “ivories”)
- finished taxidermy mounts
Importation of hunter-harvested deer and elk carcasses into Illinois is prohibited except: deboned meat, antlers, antlers attached to skull caps, hides, upper canine teeth (also known as “buglers,” “whistlers,” or “ivories”). Skull caps shall be cleaned of all brain and muscle tissue; finished taxidermy mounts; carcasses or parts of carcasses with the spinal column or head attached may be transported in the state only if they are submitted to a licensed meat processor or a licensed taxidermist for processing within 72 hours after entry2026-2027 Illinois Hunting and Trapping Digest, Illinois Department of Natural Resources, read September 23, 2026.

The Illinois agency’s own words on the meat
Illinois Department of Natural Resources publishes this:
No part of any CWD positive animal should be consumed by humans or other animals.Chronic Wasting Disease Sampling, Hunt Illinois, Illinois Department of Natural Resources, read September 23, 2026. Read it at the source
That sentence is reproduced whole and unedited because it is the agency’s statement rather than a summary of one, and 30 of the 50 states here publish one of their own. The wording differs between states.
CWD in Illinois: status, zones and baiting
Illinois Department of Natural Resources has confirmed the disease in Illinois's wild deer. The first confirmed case dates to 2002. IDNR says the disease now reaches 28 counties, with several core areas across northern Illinois, and names Stark, Scott and Effingham as its newest detections..
- First confirmed case
- 2002
- Baiting and feeding
- Baiting and feeding banned statewide
- Moving an animal out of a zone
- In the eighteen named CWD surveillance counties a deer killed in a firearm season may not simply be driven home; it goes whole or field dressed to a designated check station the same day, where it is sampled and given a permanent leg tag.
- Carcass waste
- IDNR asks that carcass parts be buried under six inches of soil or sent to a landfill, and calls this critical for a deer taken in a CWD area and moved elsewhere in the state.
This program, in conjunction with increased hunter harvest, successfully kept CWD prevalence at or below 5% from initial detection in 2002 until 2023.2026-2027 Illinois Hunting and Trapping Digest, Illinois Department of Natural Resources, read September 23, 2026. Read it at the source
Zone boundaries are redrawn between seasons more often than any other rule here, usually after a new detection near an existing line. The map linked above is IDNR's own and is the one that governs.

Illinois read September 23, 2026 from 2026-2027 Illinois Hunting and Trapping Digest, Illinois Department of Natural Resources, linked above. Carcass rules, zone boundaries and sampling requirements change between one season’s regulations and the next, and a state can add a rule mid season after a new detection, so the IDNR document linked above is the one that governs. Every state is on the CWD testing hub.
