Chronic Wasting Disease (CWD) of Deer and Elk

Chronic wasting disease (CWD) is a progressive, fatal disease of the nervous system of cervids such as mule deer, white-tailed deer, and elk. It is known as a transmissible spongiform encephalopathy (TSE). Other TSEs include scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle, and Creutzfeldt-Jakob disease (CJD) in humans.

In Canada, CWD is a reportable disease under the Health of Animals Act, and all cases must be reported to the Canadian Food Inspection Agency (CFIA).
