CWD Watch

CWD Hunters' Toolkit

It is important for all hunters to be educated and knowledgeable about chronic wasting disease (CWD). Hunters' actions play an important role in reducing the spread of CWD and providing safe, healthy food for themselves and their families. As you prepare for the 2019 deer hunting season, check out our new CWD Hunters' Toolkit

CWDWatch features a series of resources related to College of Veterinary Medicine research and response to chronic wasting disease, which is causing deep concern for hunters, landowners, and members of the public where CWD affects deer and other cervid populations.

CWDWatch is the Center for Animal Health and Food Safety's fall 2019 Emerging Issues feature.  Here we provide scientific and animal health-based evidence to help you understand what is known and not yet known about CWD and its impact across the upper Midwest.  Check back in throughout the fall for additional resources, including conversations with experts, a CWD toolkit for hunters, and video presentations.

What is chronic wasting disease?

Cervids

CWD is a neurological disease affecting the cervid family. This includes white-tailed deer, mule deer, moose, elk, and reindeer.

Neuron icon

Symptoms

The most obvious sign of CWD is weight loss. Other symptoms include poor balance, drooling, confusion, and drooping ears.

Brain icon

Prion Disease

CWD is a prion disease. These occur when normal proteins in a healthy animal or human are misfolded into abnormal shapes.

Transmission

Infectious prions can be shed through an infected animal's saliva, blood, feces, urine, and antler velvet.

CWD Conversations is a series from CAHFS and the Minnesota Center for Prion Research and Outreach (MNPRO) highlighting key facts about chronic wasting disease. 

Stay tuned for future conversations and interviews with Minnesota DNR scientists, the diagnostic development team, state legislators, Minnesota landowners, and human health experts.

  

Chronic wasting disease can easily spread in nature, and it can take up to 2 years for CWD to kill an infected animal. But why is that?

  

CWD has been found in 10 MN counties since 2002: Aitkin, Stearns, Lac qui Parle, Olmsted, Ramsey, Fillmore, Crow Wing, Meeker, Winona, and Houston

Minnesota Center for Prion Research and Outreach (MNPRO)

MNPRO is a hub within the College of Veterinary Medicine for combatting chronic wasting disease at the University of Minnesota. As an incubator for cutting-edge prion research, MNPRO brings together a range of UMN faculty and external collaborators with expertise in prion diseases, animal health, cellular biology, nanotechnology, and infectious disease.

Future Research 

  • advanced prion decontamination strategies
  • real-time rapid CWD diagnostics and surveillance
  • ecological remediation strategies for soil and vegetation
  • vaccine development
  • assessment of zoonotic potential of CWD
