Similar To Mad Cow Is Affecting Wild Deer, Elk In U.S.

(CBS) In the second report in a three-part series, CBS News
Correspondent Vince Gonzales reports on a mad cow-like disease
that destroys the brain and is killing deer and elk in the
American West.
Although
there's never been a case of mad-cow disease reported in
the United States, a very similar disease that destroys
the brain is killing deer and elk in the American West and
it's spreading.
Wyoming
state veterinarian Tom Thorn said that mad cow disease drew
a lot of attention to it. "What we watch for in an
affected deer is kind of a hollow look in their eyes, they
drink a lot. They don't eat very much."
They
waste away, which is why the always-fatal disorder is called
Chronic Wasting Disease, or CWD. The animals also behave
strangely, losing their fear of humans as CWD destroys their
brains. But an infected animal can look totally normal in
the early stages of the disease, when an autopsy can detect
it.
CWD
was first noticed at a Colorado research facility in 1967.
Mike Miller with the Colorado Division of Wildlife told
a government committee recently, "What we are seeing
is an epidemic occurring in slow motion."
Scientists
say the epidemic is slowly spreading among wild deer and
elk in Nebraska, Wyoming and Colorado, where at least 15
percent of some wild herds are infected. It's also been
found on game farms in five states and one Canadian province.
In a video produced by wildlife officials in Colorado
and Wyoming, hunters are told, "relatively little is
known about chronic wasting disease." And they're warned
to wear gloves and avoid touching or eating parts of the
animal where the disease is concentrated: the brain, spinal
column, lymph nodes, tonsil, spleen and bone marrow.
When
it was detected in Montana, drastic measures were taken.
Scores of game farm elk were incinerated. Dozens of deer
on nearby land were hunted by helicopter, killed and tested
to keep this highly contagious disease from spreading.
Hunters
are being used to control the spread of CWD in the wild.
In Colorado the hunting season was extended this year in
some disease areas as a way to try and lower the diseased
animal population. Hunters in some sections of the state
must drop off deer heads for CWD testing. Testing is voluntary
in Wyoming and Nebraska.
Wildlife
officials insist that as long as hunters are informed about
CWD and take precautions, the disease is not a human health
threat.
Thorn
argues, "You cannot say with 100 percent certainty
that it won't transmit to people, but there is no evidence
that it will transmit to people."
When
asked if he was concerned about CWD, Thorn said, "No.
I've lived here quite a long time. I've hunted here. I just
have not seen any credible evidence that it's going to kill
me or anybody else.
Despite
all the official assurances, some hunters and their families
fear eating diseased meat could infect them with the same
fatal brain disorder that's killing deer and elk.
"I've
hunted in this area and I've been eating deer all my life,"
said Chris Melani, who shot a deer in Colorado and, as required,
turned in the head for testing. He says he was told he would
be notified within three weeks if his deer had the disease.
"I
didn't get a notice so I figured everything was ok with
the deer. We started eating it," he said.
Melani,
and his then-pregnant wife Deb, also sent some of the meat
to a sausage maker who sold it to other customers. The Melani's
gave their sausage to friends and family as Christmas presents.
Then, almost two months after his hunt, Melani received
a letter.
"I
was shocked when I started reading it, recalls Melani.
His
deer had CWD.(click

"What's
done is done. You just go on with your life and hope it's
healthy," Melani said.
But
Jay Whitlock didn't get to go on with his life.
Jay,
an Oklahoma hunter, was 27 when he developed a brain disorder
similar to CWD and mad cow disease.
Julie
Whitlock said, "Jay's case is not genetic. They have
ruled that out. And they said we'll probably never know
actually how Jay did get it."
Jay
Whitlock died a year after CBS News spoke with him.
His
case, and two others, were discussed at a recent government
meeting on Chronic Wasting Disease.(click

for the meeting.)
Although
the victims ate deer meat, scientists could not link their
deaths to CWD.
Dr.
Ermias Belayof the CDC told the FDA panel, "However,
our conclusions are limited to three patients and continued
surveillance remains very critical to continue to monitor
the possible transmission of chronic wasting disease to
humans."
There
is evidence, at least in the lab, that in rare cases this
disease can alter human brain tissue, almost as effectively
as mad cow disease.
The
government says, so far, there is no proof any humans have
been infected by deer and elk. But after the deaths in Europe,
no one is willing to say it can't happen here.
