The results are in! All samples tested in Ontario came back negative for chronic wasting disease! Thanks again to the hunters who participated in both of our surveillance zones: eastern Ontario, where 307 samples were tested, and southwestern Ontario, where 457 samples were tested.
Chronic wasting disease is a fatal brain disease affecting mostly white-tailed deer and elk. Since 2002, our science staff have tested over 12,400 samples, with no positive cases found in wild deer in Ontario. Our science staff use a risk-based model to decide where to survey each year, which increases the chances of detecting this disease as early as possible.
