CWD Testing


Testing required through Jan. 14, 2018

CWD sampling results

You can view results from all areas tested for CWD. Results will be updated on weekdays as they become available.

Outside of deer permit area 603, hunters will not be notified of their test result unless their deer tests presumptive positive for CWD.

Use the interactive map above to view locations and information on stations where mandatory sampling occurs from 8 a.m. to 7 p.m. on Monday, Nov. 6, through Sunday, Nov. 26.

Deer must go to
Chatfield or Preston

Mandatory testing will be conducted in DPA 603 from 8 a.m. to 7 p.m. on Monday, Nov. 6, through Sunday, Nov. 26, at stations at Magnum Sports in Chatfield and the Preston forestry office.

Hunters must take their deer to one of these stations to have their deer sampled for CWD. All hunters also must comply with carcass movement restrictions.

For 603 hunters only, DNR will provide cold storage at Preston until a test result is received.

What to do

  1. If you shoot a trophy deer and want to have it mounted, contact a participating taxidermist authorized to take a CWD sample for DNR.
  2. Field dress (gut) your deer as you normally would.
  3. Register you deer via phone, internet or walk-in big game registration station.
  4. If the deer will be mounted, watch a video showing how to properly cape your deer.
  5. Come to Magnum Sports in Chatfield or the Preston forestry office with your deer so DNR staff can extract lymph node samples.
  6. DNR will provide a refrigerated trailer at the Preston DNR Area Forestry Office during the entire firearms season (A and B seasons, Nov. 4-26). This allows hunters that harvest a deer from inside permit area 603 to temporarily store it and comply with carcass export restrictions.
  7. No deer harvested outside permit area 603 can be stored in this refrigerated trailer. Hunters are responsible to check their results online. When a negative test result is received, hunters must come to the Preston office from 9 a.m. to 7 p.m. to pick up their deer.
  8. Hunters can take meat out of the zone immediately but the carcass (head with brain and spinal column) cannot be moved outside deer permit area 603 until a negative test result is received so hunters must:
    • Make arrangements to refrigerate the carcass before the deer is processed;
    • Cut their deer into quarters and other pieces; or
    • Bone-out the meat.
  9. Ensure no spinal column or brain matter is included with the meat or on the antlers.
  10. Properly dispose of carcass remains. There will be a dumpster at the DNR forestry office in Preston for hunters who don't have a way to dispose of remains.
  11. The Preston dumpster is being provided as a courtesy for deer carcass disposal only. It will be removed if people attempt to process deer there or use the dumpster for trash disposal.
  12. CWD test results can be searched online using your 9-digit MDNR number.
