Deer being culled by thousands in lower Laurentians to curb spread of chronic wasting disease

A mayor from a small town on the edge of the Laurentianssaysadecision to cull some3,000 domestic deer in his area is being met with mixed emotions, as peopleworry the disease may have alreadyspread beyond theinfected animal discovered ata local breeding farm last month.

"I drive by there often, and the domesticdeer are always in contact with the wild deer,"Grenville-sur-la-Rouge Mayor Tom Arnold toldCBC'sQuebec AM. "There's no buffer zone that existsbetween the two."

Thatsingledeer the first in the province was discovered inmid-September atHarpurFarms, setting off a chain reaction all the way up to the federal level.

As health officials work to determine if the disease has,in fact, spread, the farm has beenquarantined, hunting prohibited in the area until Nov. 18, andtesting throughoutthe region has begun.

So far, no more deer, wild or domestic, have tested positive.

Some citizens support the cull,Arnold said, while others feel it is an extreme measure given that there are so many wild deeraround the town, about 80 kilometres northwest ofMontreal, that could be affected, as well.

Arnold said people are concernedthe problem will be around for years to come, in an area that's developed a localeconomy arounddeer farming and hunting.

While hunters are encouraged to monitor animals for signs of the disease, suchas subtle head shivering or aggression, aresearch biologist at UniversitLaval, Prof.Jean-PierreTremblay, says the disease has an incubation period of up to five years.

Quebec continues the cull, testing

Wildlife officershave alreadykilled dozens of wild deer near Harpur Farms.

Deer that shared thepen with the infected animal have already been slaughtered, and the roughly 3,000 domestic deer on otherfarms in the region will be killed and tested in the coming weeks.

More than 20 centimetres of soil will have to be removed from some of the farmland, El MedhiHaddou, a veterinary officer with the Canadian Food Inspection Agency (CFIA) told Radio-Canada.

Ottawa will likely offer financial compensation to farmers who lose deer to the cull, he said.

Officials will harvest 330 wild deer in what is called the"controlled intervention zone." That is more than the number that is usually hunted, according toQuebec's Ministry of Forests, Wildlife and Parks.

In total,400 square kilometres straddlingthe Laurentians and Outaouais regionsare affected by temporary measures, such as enhanced surveillance, and aban on hunting and trapping.

Local hunters are being told they can either hunt in zones where hunting is allowed or get a refund on their licence.

No evidence of human transmission

There is no "direct scientific evidence" that suggests chronic wastingdisease canbe transmitted from cervids to humans, according to the CFIA website.

However, Haddousaid,similar illnesses like mad cow disease have been known to spread to people.

Along with testing any meat harvested near a known site of infection, theCFIAalso recommends testing animals before preparing trophies or tanning hides.

The Ministry of Forests, Wildlife and Parks requires hunters who harvest a white-tailed deer or moose within the surveillance zone to visit a registration station in the hunting area where the animal was slaughtered.

Ministry staff will take samples from the carcass and analyze them to determine if the animal is infected. Hunters are able to view test results as soon as they are available on the ministry's website.

If a sample is positive, the ministry will immediately notify the hunter.

Testing all game not possible, saysWildlife Ministry

On its website, Quebec's Ministry of Forests, Wildlife and Parkssays not everyhunter in the provincewill be able to have their game tested.

"Government efforts will be concentrated in an enhanced monitoring area where the risk of disease is greater," the site says.

Instead of having wildmeat tested, the ministryrecommends hunters minimize contact with the animal's brain,spinal cord and certain organs, and while avoidconsuming certain parts of the animal.

The websitealso lists meat-handling recommendations and regulations.
