Photo Above - Hydatid Cysts On Moose Lungs
Published in
1963, Farley Mowat's book, "Never Cry Wolf", probably
did more than anything written before or since to spread and perpetuate the
misconception that wolves only kill the old, the sick, and the weak - making
herds healthier. While published as a
true story, the book has been proven to be pure fiction, in which the author
wrote himself into the lead role, as a research scientist sent alone into
Canada's wild north to determine if wolf predation was the cause for the
dramatic loss of hundreds of thousands of caribou.
In reality, he was the junior member
of a research team, which indeed did come to the conclusion that the herds were
being decimated by wolves. However, in
his fictitious story, Mowat reached a completely different finding. He blamed the loss of the great herds to the
spread of diseases and parasites - and there is likely some truth to that. What he failed to share was the origin of
all those cysts found on the internal
organs of the caribou he claimed to have dissected.
The Canadian wolves that the U.S.
Fish and Wildlife Service brought down to put "Wolf Recovery" in Montana, Idaho and Wyoming on the fast
track to success also brought with them a tiny tapeworm, known as Echinococcus
granulosus. Those wolves were
supposed to have been treated for such parasites before being released into the
Greater Yellowstone Area in 1995 and 1996, and eventually in other areas. Apparently that was not done, or the
treatment was ineffective. By 2008, more
than 60-percent of the wolves tested in Montana and Idaho were infected with
the tapeworms, and a more recent study in the Yellowstone area revealed that
approximately 80-percent of the wolves tested positive for the parasite.
What
are the dangers of having this parasite in the Northern Rockies ecosystem, and
how does the parasite spread?
Many of the wolves tested have been
literally infested with thousands of the Echinococcus granulosus tapeworms,
which deposit their eggs in the digestive tract. Each and every time an infected wolf
defecates, the pile of scat left behind is loaded with thousands of the
microscopic eggs. These are easily
spread far and wide by mountain breezes, rain, on the shoes of hikers, by the
rushing waters of a mountain stream, on the tires of a mountain bike, or in the
fur of wolves and other animals - including dogs.
Elk, moose, deer and other big game,
as well as livestock, ingest eggs which have settled on blades of grass, on the
leaves of plants on which they forage, or perhaps while taking a drink. The eggs are then carried by the blood stream
throughout the body, where they can form the hydatid cysts that Farley Mowat
wrote about in his book. Hunters in the
Northern Rockies are now finding those same cysts on the lungs and livers of
big game they harvest.
Should
they be concerned about eating the meat from these animals?
Dr. Valerius Geist, a wildlife
ecologist with the University of Calgary in Alberta, says, "Native people have been eating hydatid
infected moose, caribou and deer forever. The meat is safe."
He points out the
cysts contain thousands of tiny tapeworm heads floating in a liquid. Geist
claims that in elk, deer, moose, caribou, etc., neither the cyst's liquid, nor
the tapeworm heads are anything to worry about. Stating they cannot infect you.
So,
what's the danger?
Humans
can contract hydatid disease only through the ingestion of E. granulosus eggs,
which originate from the scat of wolves, coyotes and other canines infected
with the tapeworms. One of the most
common carriers to humans is the family dog, which can bring those eggs right
into the family home. Dogs are notorious
for rolling in the scat of other canines.
And even if they don't, a long run through the grasses of where wolves
live could mean bringing in dozens or hundreds of those eggs in their fur or
hair, where they are deposited in the carpets where children play. Or, they could be transferred directly to
humans when the dog is loved on, and returns the affection with a good healthy
lick or two.
Likely
one of the more common ways for humans to ingest the eggs is to have them on
their hands when eating a sandwich, a piece of fruit, or maybe even something
as delightful as a sweet glazed donut.
Dr. Geist points out that hydatid cysts don't pose that big a threat
when just one or two of the cysts form on or in the lungs or liver, where they
are encapsulated by the host tissue, and may eventually calcify. However, he points out that a hydatid cyst
that forms in the brain can prove lethal.
He also notes that multiple cysts forming on the lungs, heart or on long
bones can become medically problematic, interfering with organ function and
possibly could overcome the immune system.
Dr.
Geist has stated emphatically, "Should the cyst burst (internally),
then the liquid will generate a severe allergic reaction. Anaphylactic shock
may be the consequence. And that can
kill the patient on the spot!"
Farley
Mowat's claim that the hydatid cysts and other parasites were the reason for
the precipitous crash in caribou numbers could be shown to be true to a certain
degree. However, unless the internal
organs of the animals were riddled with the cysts, it's unlikely that animals
died directly due to those cysts. The
most likely consequence of the caribou ingesting E. granulosus
tapeworm eggs, and having multiple cysts form on internal organs, was that it
impeded the ability of the animals to elude a pack of wolves for any
distance. And that is especially true if
a number of large cysts had formed on the lungs, weakening their function and
lessening their air capacity.
A
better question might be, is the same thing now happening with the elk, moose,
deer and other big game populations in the Northern Rockies?
In 2011, the LOBO WATCH website sent an e-mail out to the directors of both Montana Fish,
Wildlife and Parks and the Idaho Department of Fish and Game, plus several
dozen wildlife managers, regional and department supervisors, and to board
members of the game commissions in these two states, to inquire whether or not
these wildlife agencies have been monitoring the occurrence of hydatid cysts in
game harvested by hunters. And if MT FWP
or IDFG has not been monitoring this threat to our wildlife resources, to ask "When are you going to start?"
That
e-mail also went to hundreds who have also been impacted by wolf depredation,
and many who now continue to live with the threat of contracting hydatid cysts. Those recipients included the heads of
national and state wildlife conservation organizations, outfitters and guides,
elected officials, and many sportsmen.
One,
a rancher on the Flathead Indian Reservation, e-mailed back with details about
a pair of wolves killing one of his calves.
He also shared that the National Bison Range, which is located inside
the Flathead tribal lands, had recently reported the bighorn sheep and
pronghorn herds have had newborns with "some sort of lung
disease".
Robert
Fanning, the founder of the Friends of the Northern Yellowstone Elk Herd, also
sent out an e-mail to those wildlife agency recipients with a similar
statement, "Many, many big
horn sheep have been killed by WY agency 'scientists' this year to analyze so
called 'problems with their lungs'. Why haven't those results been released to
the public?"
As residents of the Northern Rockies
have learned more about the spread of the Echinococcus granulosus tapeworm,
and the growing occurrence of hydatid cysts being discovered inside harvested
big game animals, the more many now feel that the large number of wild sheep
which have been destroyed due to "pneumonia" may have been
killed for the wrong reason - or to cover up something. Likewise, most feel that it is only a matter
of time before the number of reported cases of hydatid disease among humans
begins to escalate. As rare as the
disease may be in the Lower 48 States, in other parts of the world where there
are large numbers of parasite carrying wolves, the number of reported cases is
much higher.
Across Alaska and Canada, where an
estimated 50,000 to 75,000 wolves roam the North woods and tundra, the rural
human population is extremely sparse. In
all of the Yukon's 186,661 square miles, there are only about 34,000 residents - of
which, some 27,000 live the capital city of Whitehorse. That gives the other 7,000 or so rural dwellers a lot of elbow room. Next door in the Northwest Territories, around 42,000
people have 519,734 square miles to roam.
Nunavut offers even more remote living, with just over 31,000 people sharing
808,185 square miles. Across the Earth's
northern ice cap, in Russia's northern regions rural human inhabitation is even
more sparse in many equally as expansive wild areas - areas with as many as
100,000 to 150,000 wolves.
As sparsely populated as these areas
may be, with so few people living amongst such large wolf populations, the
number of people infected by hydatid cysts is much higher than in the Northern
Rockies. The residents of those remote
regions live where wolves are more prevalent, and where their contact with
wolves, or what wolves have left behind, is much greater.
Dr. Geist says this is largely due
to the high dependency on dogs by residents of the Far North. In much of this country, the only winter
travel is via dog sled, and most families in the northern regions of North
America and Asia keep and maintain a large number of sled dogs - which are
generally fed the offal and raw discarded portions of caribou, reindeer and
moose - many of which were very likely infected with hydatid cysts. While those dogs are very rarely allowed into
the homes, and generally kept well away from human dwellings, those who work
and handle them very likely carry many Echinococcus granulosus tapeworm
eggs back into the home. Geist says that
one major source of egg transfer from those dogs to humans is probably the
handling of fecal soiled sled harnesses.
The Public Health Agency of Canada
recognizes the danger of being exposed to E.g. eggs to be so great, the agency
has issued a Material Safety Data Sheet for the handling of Echinococcus
granulosus tapeworms for researchers or health and medical
professionals. (That MSDS can be found
at http://www.phac-aspc.gc.ca/lab-bio/res/psds-ftss/msds54e-eng.php )
In Montana and Idaho, state
officials have all but ignored the health threats posed by the tiny tapeworms
which are being contracted by a growing wolf population. And the eggs of those tapeworms now cover the
landscape by the billions. Perhaps that
is why the wildlife agencies have so seriously downplayed the real number of
wolves in each of these states, maybe they are afraid that sooner or later
someone is going to start doing some real math.
In Montana, FWP has had the
propensity to precede wolf population estimates with the wording "at
least", which means they really don't have a clue about the real
number of wolves in the state, but feel that a very acceptable, and
comfortable, minimum guess is whatever figure they happen to be using at the
time. In 2011, they claimed there were "at
least" 653 wolves in the state.
However, simple math indicated the true "at least"
number to be more like 1,500 to 1,700, with the possibility of 2,000 to 2,500
wolves in the state. Still, using FWP's
overly conservative number, if 60-percent of the wolves were infected, at that time there were approximately 392 wolves spreading E.g. eggs across nearly all of the
western one-third of the state...on a daily basis.
One estimate stated that each and
every time a wolf defecates, another 2,000 to 3,000 of those eggs contaminate
the region. And if each wolf left just
one pile of scat a day, an average of nearly 1,000,000 tapeworm eggs were
released into an environment being shared with elk, moose, deer, livestock,
pets and humans. Now, consider the
possibility, or likelihood, that FWP was way off base with their low ball
estimate of wolf numbers, and the real number was closer to 2,000 wolves - "at
least" 60-percent of which carried and spread the threat of the
tapeworm. Making the situation worse is
that those eggs can survive for months on end, meaning that western Montana is
now one great big E.g. incubator, contaminated with billions of the tapeworm
eggs...waiting for a new intermediate host to come along. Then, the cycle is complete, and begins again
when wolves kill an infected animal and feeds on the cyst covered organs and
flesh.
In most regions of the world where
cystic hydatid disease has been most prevalent,
it has been where very few people have been exposed to the environment
of tens of thousands of wolves. Here in
the Northern Rockies we now have a new dilemma - and that is millions of people
sharing the environment of just several thousand Echinococcus granulosus
infected wolves. Montana is now home to
right at 1-million people, while Idaho is home to just over 1.5-million
residents. Yellowstone National Park
claimed that more than 3-million people visited in 2011, and Glacier National
Park welcomed more than 2.2-million visitors that year. According to the University of Montana,
altogether 10.5 million travelers visited Montana in 2011. If the tourism of Idaho and Wyoming are also
thrown into the equation, 15 to 20 million people could have been exposed to
the E.
granulosus eggs now covering the land, wafting around in the mountain
breezes, or flowing downstream in the waterways of the Northern Rockies.
If
these people had been forewarned of the possible danger, how many of them would
have elected to visit other regions of the country?
What
has made the Intermountain West such a draw in the past has been its
abundance of wildlife, which is now fast disappearing - and has been ever since
the introduction of non-indigenous Canadian wolves - and the Echinococcus
granulosus tapeworm. With the
percentage of wolves contaminated with the tapeworm now on the rise, it is very
evident that an extremely high number of the elk, moose, deer and other big
game harvested by hunters have become intermediate hosts, and carry the burden
of tapeworm filled cysts on and in their internal organs.
Bob Fanning, who was a 2012 Montana
gubernatorial candidate, says if the public health issue of E.
granulosus is not confronted directly, openly, honestly and
professionally with science instead of politics to stop the cover up of hydatid
disease, not only would Montanan's completely lose trust in MT FWP, but they
would stop obeying that agency as well.
He added, "The grey wolf has been
forced on us and because of the lethal disease they can introduce to the human
population, we have a natural, lawful right to defend ourselves, our children
and grandchildren."
LOBO WATCH feels it is time to share
this disaster with those who have brought it to us. During the 2013 fall hunting seasons, hunters
are encouraged to carry a heavy duty plastic trash bag with them, and to
deliver any cyst covered internal organs found in game directly to MT FWP or
IDFG regional offices, and demand that they be studied. These agencies should have been monitoring
the occurrence of such cysts ever since wolves were first released into the
Northern Rockies, but have not. Now it's
time to force them to do their job.
If taking those organs to FWP or
IDFG isn't possible, Val Geist says that a hunter should build a hot fire and
burn those infected internal organs to break the E.g. cycle. - Toby Bridges, LOBO WATCH
