CWD fears spread far and wide

Nearly every state keeping watch for fatal brain disease

By Gary Gerhardt, Rocky Mountain News
October 18, 2004

Five years ago, Colorado was among a handful of states that had a
surveillance program for chronic wasting disease.

Today, nearly every state in the U.S. has a program, hoping it never
finds that the fatal prion disease has infected its deer and elk herds.


First discovered in Colorado in 1967, CWD now has spread to 11 other
states and two Canadian provinces.

Last year, Colorado found the disease in 248 deer and elk from 16,431
deer, elk and moose heads submitted for testing.

CWD is a neurological disease that attacks the brains of infected
animals, causing them to become emaciated, display abnormal behavior and
lose bodily functions. Stricken animals always die. How it is
transmitted and whether it affects all animals still is being studied.

CWD has a loose relationship to mad cow disease, scrapie in sheep and
Creutzfeldt-Jakob disease in humans. However, there has been no evidence
that CWD is a risk to human health.

The first combined deer and elk big-game rifle season opened Saturday.

In Colorado, there is no longer mandatory testing throughout most of the
state.

Anyone wanting to submit a head for testing to the Colorado Division of
Wildlife will have to pay $15.

However, six game units encircling the Denver metropolitan area, eight
between Colorado Springs and Pueblo, and 18 in southwestern Colorado
will waive testing fees. The waiver is meant to encourage hunters to
submit heads for testing in areas where the division needs additional data.

"We are interested to learn if CWD is spreading into new areas," said
Todd Malmsbury, Colorado Division of Wildlife spokesman.

"So far we don't have any reports of CWD in southwestern Colorado, but
we are concerned we may not be getting enough submissions from the area
to be certain."

Last May, wildlife officials were floored to find a dead mule deer buck
in the back yard of a home in the southwestern section of Colorado Springs.

The animal tested positive for CWD.

It was 45 to 50 miles south of a dozen infected animals found between
Chatfield Reservoir and Sedalia - the farthest south any infected animal
had been found in Colorado.

Like Colorado, the majority of western states are relying on voluntary
submissions of heads to be tested for CWD.

Marty Frentzel, of the New Mexico Game and Fish Department, said the
agency has a voluntary system, with one mandatory unit where only 10
hunters have licenses and any animals taken will be tested.

"We got 230 samples last year and hope for 600 to 700 this year," he said.

"Back a few years ago when all the publicity came out about CWD, we got
768."

Along with Colorado and Utah, the Western states with the most
free-ranging deer and elk infected with the disease are Wyoming and
Nebraska.

Michelle Zitek, of the Wyoming Game and Fish Department, said it has a
voluntary system and will be collecting most samples at check stations
and from processors.

"We started sampling statewide last year and the emphasis has been on
the 'leading edge' of where the disease is found," she said.

"It now has spread westward to Baggs (southwest of Rawlins) and north to
Worland."

She said the state's hot spot last year was Casper, where as many as 32
percent of some herds were infected.

Phil Richmond, of the Nebraska Game and Parks Commission, said the
agency has voluntary submissions and does random samples by asking
hunters if they will provide samples when they stop at check stations.

"Most of our concern is in the Panhandle, and we are paying additional
attention to the North Platte River area," he said.

"We found some infected deer east of Alliance and will take all the
heads we can that are submitted in the Panhandle."

Last year, officials sampled 4,200 heads from the more than 50,000 deer
harvested, and are hoping for more this year.

CWD has been found, either in the wild or domestic herds, in Colorado,
New Mexico, Utah, Wyoming, Montana, South Dakota, Nebraska, Kansas,
Oklahoma, Minnesota, Wisconsin, Illinois, and Alberta and Saskatchewan,
Canada.

Greetings,

I don't know how folks can print this and keep a straight face and or
sleep at night. THIS is exactly what was said about BSE to humans.
UNTIL they finally did document it. CWD transmits to primates and
transmission studies on man has never been done. SO to say this is
a blantant fabrication of the facts...

THERE is plenty of evidence, just that belay et al at cdc are
ignoring it and this;

AS implied in the Inset 25 we must not _ASSUME_ that
transmission of BSE to other species will invariably
present pathology typical of a scrapie-like disease.
