The Missouri Department of Conservation reminds deer hunters that it will be holding mandatory CWD sampling during the opening weekend of the November portion of firearms season, Nov. 12 and 13, for hunters who harvest deer in 34 of 38 MDC CWD Management Zone counties.
CWD is a deadly, infectious disease in deer and other members of the deer family (cervids) that eventually kills all animals it infects. There is no vaccine or cure. CWD can be spread from direct deer-to-deer contact, through improper disposal of deer carcasses, and through the environment by deer contacting infectious material from other deer. Hunters play a critical role in helping MDC find and manage the disease by having their deer tested and following carcass-movement restrictions and other CWD regulations. Learn more at this link.
CWD Management Zone
MDC designates counties where CWD has been found and counties within 10 miles of where CWD has been found as part of its CWD Management Zone. The 2022 CWD Management Zone counties are Adair, Barry, Barton, Camden, Cedar, Chariton, Christian, Clark, Crawford, Franklin, Gasconade, Greene, Hickory, Howell, Jefferson, Knox, Laclede, Linn, Macon, McDonald, Mercer, Oregon, Ozark, Perry, Polk, Pulaski, Putnam, Ripley, St. Charles, St. Clair, St. Francois, Ste. Genevieve, Stone, Sullivan, Taney, Vernon, Warren, and Washington. MDC notes that Barton, Greene, Ripley, and Vernon counties are new to the CWD Management Zone this year.
Mandatory CWD Sampling Nov. 12 and 13
Hunters who harvest deer in 34 of the 38 counties in the CWD Management Zone during the opening weekend of the November portion of firearms deer season (Nov. 12 and 13) are required to take their harvested deer or the head on the day of harvest to one of MDC’s numerous CWD mandatory sampling stations located throughout the zone. Sampling and test results are free.
This year, sampling is mandatory on Nov. 12 and 13 in all CWD Management Zone counties except Gasconade, Knox, St. Charles, or Warren counties. CWD mandatory sampling stations will not be available in these counties.
MDC Cervid Program Supervisor Jason Isabelle explained that this year’s sampling efforts will focus on CWD Management Zone counties at the greatest risk of having new areas of CWD infection.
“With 38 counties in the CWD Management Zone this year, we’re having to prioritize where to focus our sampling efforts within the Zone on opening weekend,” Isabelle said.
Although CWD sampling is not mandatory this year in Gasconade, Knox, St. Charles, or Warren counties, Isabelle noted that hunters who harvest deer in these counties on Nov. 12 or 13 can bring their deer to one of the CWD mandatory sampling stations located in other CWD Management Zone counties if they want them sampled. Another option for hunters in these four counties to have their deer sampled on opening weekend is to use self-service freezer drop-off stations located in these counties.
“Although freezer drop-off stations are closed on opening weekend in counties where CWD sampling is mandatory, these stations will remain open in Gasconade, Knox, St. Charles, and Warren counties,” Isabelle said. “Doing so provides hunters in these CWD Management Zone counties with additional opportunities to have their deer sampled if they so choose.”
Mandatory CWD sampling dramatically increases the number of tissue samples MDC can collect in a brief period of time. The increased number of samples gives MDC scientists a much better understanding of the distribution and prevalence of the disease — where it is and how many deer may have it. It can also help find new cases in new areas so disease management can begin as soon as possible to slow the spread of CWD.
The opening weekend of the November portion of firearms deer season is the most popular two hunting days for most deer hunters. Hunters take about a third of the state’s total annual deer harvest during those two days. Focusing on this key weekend gives MDC the best opportunity to collect the most tissue samples during a very concentrated time period.
Hunters must present their deer at a CWD mandatory sampling station within the county of harvest, with a few exceptions. Deer that will end up being delivered to a licensed meat processor within 48 hours or deer heads that will be delivered to a licensed taxidermist within 48 hours may be transported to a sampling station in any county. Hunters may also take deer heads to a CWD mandatory sampling station in another county as long as the head is left at the station after sampling.
Find CWD mandatory sampling station locations online at this link, or from MDC’s 2022 Fall Deer & Turkey Hunting Regulations and Information booklet, available where permits are sold and online at this link.
CWD sampling takes only a few minutes and consists of MDC staff cutting an incision across the neck of harvested deer to remove lymph nodes for testing. Tissue samples are sent to an independent lab for testing.
Hunters will be given a card with information on getting free test results for their deer after samples are processed. Hunters can get their CWD test results for free online at this link. Results are available within four weeks or less from the time of sampling.
Hunters presenting bucks bound for taxidermy should inform MDC staff. Staff will complete paperwork and inform the hunters about participating taxidermists taking CWD tissue samples. Another option is to remove the cape before taking the deer to a sampling station.
Before arriving at a CWD mandatory sampling station:
- Field dress and Telecheck deer.
- Bring the carcass or just the head.
- Capes may be removed in preparation for taxidermy prior to arriving at a station.
- Position deer in vehicles with head and neck easily accessible.
- Be sure the person who harvested the deer is present.
- Be prepared to find the location of the harvest on a map.
- If using a paper permit, have it detached from the deer for easy access.
- If using the MO Hunting app, have permit information available.
Carcass Movement Restrictions
Hunters must follow carcass-movement restrictions for deer harvested in a CWD Management Zone county:
- Deer must be Telechecked before any parts of the carcass may be transported out of the county of harvest.
- Whole carcasses may only be transported out of the county of harvest if delivered to a licensed meat processor within 48 hours of exiting the county of harvest.
- Deer heads containing muscle and brain tissue may only be transported out of the county of harvest if delivered to a licensed taxidermist or an approved CWD sampling station within 48 hours of exiting the county of harvest. However, on Nov. 12-13, for counties in which sampling is mandatory, deer, or the head, must be taken on the day of harvest to a CWD mandatory sampling station.
- The following carcass parts may be moved outside of the county of harvest without restriction:
- Meat that is cut and wrapped or that has been boned out.
- Quarters or other portions of meat with no part of the spinal column or head attached.
- Hides from which all excess tissue has been removed.
- Antlers or antlers attached to skull plates or skulls cleaned of all muscle and brain tissue.
- Finished taxidermy products.
CWD Sampling and Testing All Season
As part of its efforts to find cases of CWD early and help slow its spread, MDC is again offering free voluntary CWD sampling and testing of harvested deer during the entire deer season at select locations throughout the state, including some MDC offices and participating taxidermists and meat processors.
MDC also offers self-service freezer drop-off locations within the CWD Management Zone for hunters to deposit harvested deer heads to have tested for CWD. Instructions, packing supplies, and information tags are available at the sites. Freezer drop-off stations will be closed on Nov. 12-13 in mandatory sampling counties when hunters must present their deer or deer head at a CWD mandatory sampling station. Get more information on sampling and drop-off locations online at this link.
Hunters can get their CWD test results for free online at this link. Results are available within four weeks or less from the time of sampling.
