Beginning in 1997, the Candian Wildlife Health Cooperative (CWHC) and the Saskatchewan Ministry of Environment (MOE) started a chronic wasting disease (CWD) surveillance program for wild deer, elk and moose. This surveillance program was based primarily on the testing of hunter-harvested animals and to a lesser extent on the testing of sick or dead cervids. The program ended in 2012 with over 45 000 heads tested and a total of 387 positives from 20 Wildlife Management Zones. The CWHC continues to test cervids that are submitted through our diagnostic program and we have continued to diagnose CWD in new areas. Starting in 2006 the CWHC embarked on a research program in Saskatchewan with the aid of PrioNet and the MOE to look at factors affecting the spread of CWD. Phase I of the project focused on direct and indirect contact rates, habitat selection, long distance movements and survival trends as they relate to CWD. Phase II which began in 2009 focused on direct observations of mule deer and their use of environmental sites to determine risk of infection by CWD.
