The fatal infectious disease is so well established in Saskatchewan and Alberta that the federal government and some provinces are rethinking how to deal with what is commonly known as CWD.
In 2005, Ottawa announced a national strategy to control chronic wasting disease in the hope of finding ways to eradicate it. Now the emphasis is shifting to preventing CWD from spreading, especially in the wild.
"We have to realize that we may not be able to eradicate this disease currently from Canada, given that we don't have any effective tools, so we may be looking at switching from eradication to control," said Penny Greenwood, national manager of domestic disease control for the Canadian Food Inspection Agency.
The agency says it is working with the provinces and the game-ranching industry to come up with a better plan, perhaps by next spring.
"We feel that the current program that we have had in place for chronic wasting disease ... is not effective in achieving its goals," Greenwood said.
CWD is caused by abnormal proteins called prions and is similar to mad cow disease. There is no vaccine against it. Symptoms can take months or years to develop. They include weight loss, tremors, lack of co-ordination, paralysis and, ultimately, death.
