Step One: Deer Head Submission
Hunter CWD surveillance starts with the submission of hunter-harvested deer heads along with the geographic coordinates where each deer was killed in Alberta.
Depending on where in Alberta you are hunting, deer head submission for CWD testing is either mandatory or voluntary.
Be familiar with the CWD testing requirements for the area that you are hunting in.
For a map illustrating mandatory CWD testing areas in Alberta, see Related Information below for CWD Freezer Locations (Deer Hunters: Assist Us With Our CWD Surveillance).
If possible, please do not shoot deer in the head, as this can damage the lymph nodes and brain samples needed for testing. A usable sample consists of the entire head but you can remove the antlers and antler skull plate and not damage the required tissues.
Please remove the neck just behind the head – so the head takes up much less space in the freezer!
Do not remove and submit only the brain.
For so-called ‘European’ mounts, submit the following tissues:
Lower jaw
All tissues from the roof of the mouth at the back of the throat, and
The part of the brain that contains the connection between the spinal cord and the brain (this lies ~5 cm inside the big hole at the back of the skull)
Bag the two samples separately and then put the two bags together in a third bag. This keeps all tissues from one animal together.
Keep the deer head frozen.
You can drop off the frozen head at any Fish and Wildlife office in Alberta (during regular office hours)
During fall rifle seasons there are 24-hour freezer locations where heads can be dropped off. See Related Information below for CWD Freezer Locations (Deer Hunters: Assist Us With Our CWD Surveillance).
Every head submitted for CWD testing must have a green CWD identification label fixed to it (see below).
The freezers contain bags and green CWD identification labels for you to fill out (bags and labels also are available at Fish and Wildlife offices). It is very important that you:
Fill out both sides of the CWD label, providing as much detail as possible regarding the location of the submitted sample (GPS, Sec/Twp/Rge, or latitude/longitude) in addition to the Wildlife Management Unit [WMU])
Provide your complete personal contact information, so that we can contact you with test results
Fasten the CWD label securely to the head of the deer.
Keep the bottom part of the label as your record of the CWD number that identifies each specific deer head.
NOTE THAT HEADS SUBMITTED FOR CWD TESTING ARE NOT RETURNED TO THE HUNTER.
If you want to keep the antlers, you MUST take off what you want before you submit the head!
