G&F Expands CWD Surveillance this Fall
LARAMIE – Checking licenses, collecting biological data and providing
hunters with current information are all important tasks on the Game and
Fish Department’s “to do” list during hunting season.
However, one more item will be added to the list this fall: taking samples
all across the state for chronic wasting disease (CWD) surveillance.
G&F employees will be working at selected meat processors and check
stations across the state the first five days of deer seasons. In addition
to collecting the customary biological data, employees will remove lymph
nodes for CWD tests.
“In the past, we used the brain stem for CWD tests, which was time
consuming and often meant collecting the entire head. New tests have shown
that testing lymph nodes will yield as good, if not better results,
therefore we will use the new procedure this year,” said Hank Edwards, G&F
wildlife disease specialist.
Using the new procedure is faster and will allow the G&F to expand
In December 1999, the World Health Organization stated, “There is
currently no evidence that CWD in cervidae (deer and elk) is transmitted
to humans.” They further state, “… no part or product of any animal with
evidence of CWD or other TSEs should be fed to any species (human,
domestic or captive)”.
Although there is not evidence CWD is transmitted to humans, G&F officials
want to continue to monitor the disease and its effects on wildlife.
“Expanding surveillance will allow us to better understand the
distribution of this disease,” Edwards said. “Past surveillance efforts
allowed us to document CWD in new hunt areas and we hope expanded
surveillance will allow us to identify the leading edge of the disease.”
When hunters arrive at check stations they will be asked if they would
like to participate in the CWD surveillance program. If they do, trained
employees will remove the animal’s lymph nodes. This will not affect the
meat, but may affect potential to have the animal mounted.
“Hunters who wish to have their animal mounted will need to make
arrangements with their taxidermist to retrieve the head after it has been
caped if they choose to submit it for testing,” said Edwards.
Employees will record detailed information about where the deer was
harvested, and will apply barcode stickers to the hunter’s license and
corresponding samples to make sure the hunter information is matched to
the correct animal.
Testing is voluntary, but as a service to those who take time to
participate the G&F will post test results on their Web site. Hunters will
need their barcode numbers to obtain results, and results will be posted
as they become available. Completing tests will take about 12 weeks. The
G&F will notify hunters by letter if their animal tests positive.
The G&F is working with other state wildlife agencies, and will contact
those agencies in the home state of any non-resident hunter whose animal
Hunters not participating in the G&F surveillance program may have their
animal tested at their own expense at the Wyoming State Veterinary
Laboratory in Laramie. Some veterinarians around the state have been
trained to take samples and may be willing to work with hunters to obtain
samples and ship them to the appropriate place.
