Long-term monitoring sites are being established in targeted zones to obtain more information about the presence and spread of CWD in Saskatchewan.

According to some advocates and researchers, the disease is adapting and warrants more scrutiny and preventative action.

The Canadian Food Inspection Agency says some sheep in Alberta have been infected with scrapie, a fatal disease that affects the animals' nervous system.

Chronic wasting disease belongs to a family of diseases called prion diseases, which includes the human form of "mad cow disease."

The Saskatchewan Ministry of Environment announced a case of chronic wasting disease has been discovered south of Melfort.

The disease is a fatal infection of the central nervous system in deer, elk, reindeer and moose, and is similar to mad cow disease in cattle.

Hunters in Saskatchewan are being encouraged to submit heads from deer, elk, caribou and moose for CWD testing.

A wildlife ecologist says more heads are needed to get a clearer picture of the spread of chronic wasting disease.

Chronic wasting disease (CWD) – a fatal disease found in deer, elk, reindeer and moose that affects their central nervous system – was found in three new wildlife management zones in 2017.

A popular national park, located just 30-minutes east of Edmonton, is holding consultations with the public as it drafts a plan to deal with an overpopulation of elk, moose and bison. Among the options being considered is the rare phenomenon of allowing hunting in a Canadian national park.
