Montana Living — Chronic wasting disease has beeen confirmed in a deer harvested in Montana.

A second test on a tissue sample from a buck harvested in hunting district 510, south of Billings tested positive for CWD. This buck was harvested Oct. 22 about 10 miles southeast of Bridger. Initial testing received by Montana Fish, Wildlife and Parks last week showed the animal was suspect for CWD. A second sample from the buck was sent to Colorado State University for follow up testing.
“These were the results we expected,” said Barb Beck, FWP Region 5 supervisor and CWD incident command team lead. “Fortunately, we have a well-thought out response plan that will guide our steps moving forward.”  
The first test of a sample from a second buck was reported back as suspect on Tuesday. This buck was harvested on Nov. 5 about 3 miles south of Belfry, also in HD 510. A second sample from the animal is currently undergoing confirmation testing. Those results are expected next week.
In response to these detections, FWP director Martha Williams established an incident command team on Nov. 7. The team is comprised of FWP staff and representatives from the Montana Department of Health and Human Services, Montana Department of Livestock, Montana Department of Environmental Quality, and Crow Nation.
The incident command team is implementing a response outlined in FWP’s CWD Response Plan, which is currently out for public comment. The plan calls for establishing an initial response area for the purposes of a Special CWD Hunt. This hunt, should it occur, would need to be approved by the Montana Fish and Wildlife Commission and would be held after the general hunting season. The goal of the hunt would be to harvest enough mule deer to establish disease prevalence and distribution.

For Hunters

Though there is no evidence CWD is transmissible to humans, it is recommended to never eat meat from animals that appear to be sick or are known to be CWD positive. The Centers for Disease Control and Prevention recommends hunters who have harvested a deer, elk, or moose from a known CWD-infected area have the animal tested prior to consuming it. If hunters harvest an animal that appears to be sick, the best thing to do is contact FWP and have the animal sampled.
Some simple precautions should be taken when field dressing deer, elk or moose:

  • Wear rubber gloves and eye protection when field dressing.
  • Minimize the handling of brain and spinal tissues.
  • Wash hands and instruments thoroughly after field dressing is completed.
  • Avoid consuming brain, spinal cord, eyes, spleen, tonsils and lymph nodes of harvested animals. (Normal field dressing coupled with boning out of a carcass will essentially remove these parts.)

Montanans need to remember that Montana law prohibits the import of heads and spinal columns of deer, elk or moose harvested in states or provinces that have CWD in wild or captive populations.

Out of state hunters should check their state’s carcass transport restrictions since Montana is now a CWD-positive state.  Hunters should also dispose of carcass waste in a Class 2 landfill. A class 2 landfill accepts all solid waste, except regulated hazardous waste. Most major landfills in Montana are class 2. However, if you have any questions, contact city or county public works director. Disposing of carcass waste on the landscape is considered littering and it may facilitate the spread of CWD.
Additionally, hunters who are concerned about whether the deer, elk or moose they harvest is infected with CWD should have the animal tested. If the animal was harvested in the priority surveillance area, the sampling can be done at one of the check stations operated in Big Timber, Billings, Columbus, Laurel, or Lavina on Saturdays and Sundays during the general season or at the FWP Region 3 office in Bozeman or the Region 5 office in Billings.

If the animal is harvested outside the priority surveillance area, hunters can follow the directions on the web at to take and submit their own samples for testing. 

The area where the suspect and positive samples were discovered is part of the FWP priority CWD surveillance area. FWP staff are collecting samples from hunter-harvested deer in south central Montana hunting districts. Most samples are collected at check stations and hunters receive a card with a sample number used to check test results. FWP is encouraging hunters who harvest deer within the priority CWD surveillance area, and especially hunting districts 502 and 510, to submit their animals for testing. If this is not done at a check station, hunters can call or come to the FWP Region 5 office on Lake Elmo Drive in Billings at 406-247-2940 from 8-5 weekdays.
CWD is a progressive, fatal disease affecting the central nervous system of mule deer, white-tailed deer, elk and moose. It is a slow-moving disease.

However, according to FWP if left unmanaged, chronic wasting disease could result in long-term population declines within affected herds.
