This is a warning to outdoor users about a potentially deadly biological event that could result from one’s curiosity to poke at and kick through scat from wolves, coyotes and foxes. Of course not everyone knowingly does this but many hunters, trappers and simply the curious, want to know what these animals have been eating.

Back in the end of November I gave you a link to a story, “Of Wolves and Worms”. That story introduced many of us to the subject of worms being found in wolves in the Greater Yellowstone area.

According to a new study out in the October issue of the Journal of Wildlife Diseases, three-millimeter-long tapeworms known as Echinococcus granulosus, are documented for the first time in gray wolves in Idaho and Montana. And the authors didn’t just find a few tapeworms here and there… turns out that of 123 wolf intestines sampled, 62 percent of the Idaho gray wolves and 63 percent of the Montana gray wolves were positive. (Ew!) The researchers wrote: “The detection of thousands of tapeworms per wolf was a common finding.” (Again… Ew!!) This leads to the interpretation that the E. granulosus parasite rate is fairly widespread and established in the Northern Rocky Mountain wolves.

There is discussion about how some think the worms ended up in the wolves in this region but the article tends to downplay any serious concerns people should have from coming in contact with these tapeworms and the eggs they leave behind.

In the comments section of the article, Will Graves, author of the book “Wolves in Russia: Anxiety Through the Ages“, left his thoughts on his own research discoveries about the dangers to humans of these parasites.

In the first paragraph in my letter to Mr. Bangs dated 3 October 1993 on the DEIS (Draft Environmental Impact Statement) which was titled “The Reintroduction of Gray Wolves to Yellowstone National Park and Central Idaho,” I warned about the damages and problems wolves would cause to Yellowstone and other areas by carrying and spreading parasites and diseases over larger areas. Some of these parasites are damaging not only to wild and domestic animals, but can also be dangerous to humans. One of these parasites is Echinococcous Granulosus and Echinococcus M. Since 1993 I have been working to tell people what I have learned from about 50 years of research on the characteristics, habits and behavior of Russian wolves. From that research I came to the conclusion that one of the most serious consequences of bring wolves into the US would be the wolves carrying and spreading around damaging/dangerous parasites and diseases. I did my best to explain this in my book titled, “Wolves in Russia – Anxiety Through the Ages” edited by Dr. Valerius Geist. Details about my book are in my web site: wolvesinrussia.com.

After several years effort, I finally recently obtained help from the U.S. Department of Agriculture, Parasitic Research Center in Beltsville, MD. This research center will try to conduct research on the blood taken from wolves in our western states. Oneparasite they will be researching is to determine if wolves carry and spread the parasite Neospora Caninum around. It is established that coyotes and dogs carry this damaging parasite.

I remember that about two years ago there was a report about one wolf carrying Echinococcus Granulosus in Montana.

Much more research is needed about the danger wolves bring to our environment. Some of the parasites carried by wolves are dangerous to humans.(emphasis added)

Around this same time that Will Graves posted his comments, he contacted me by email and asked if I could somehow be of assistance to him in obtaining blood samples from wolves taken during the Idaho and Montana wolf hunts. The word went out quickly and hopefullyGraves gets what he needs to help him in his research. This can become extremely valuable information for all of us.

In the meantime, Dr. Valerius Geist, professor emeritus University of Calgary and Dr. Charles Kay, of Utah State University, who holds degrees in wildlife ecology, environmental studies and wildlife biology, exchanged thoughts on the discovery of worms in Yellowstone wolves in emails I received.

Well, Charles? What else is new? What did we warn about, how we were censored as alarmists………………………
And yes, a colleague assured us that all that is not a problem for us, but for some native types. Nothing to worry about, really. Remember how, early on, we put out a warning – do not kick dry wolf feces or poke about in such looking for evidence of food habits. Do not handle wolf feces as it will disturb the tiny Echinococcus eggs that float up like little dust cloud to envelop you, and you are very likely to ingest some of that “dust”. This know-how, which we older Canadian types carried away from our parasitogy lessons was poo-hood by some American colleagues. Wolves are after all, harmless! Remember the question we posed: is it really such a great idea completing ecosystems when the progression is herbivores, carnivores, finally diseases and parasites?

It is not my intention nor that of Drs. Geist and Kay to attempt to instill unnecessary fear in people but to educate, as it was back in the day before wolf reintroduction. There are very important lessons and warnings that all should heed and take into consideration when in the woods or maybe even in your own back yard.

Dr. Geist emailed me the other day and asked me if I would be kind enough to post this information so that anyone and everyone will be aware of the potential for some very serious health issues.

Urgent: could you make a point of it that now, that we know that the majority of wolves are infected with Echinococcus, that all hunters control their curiosity and not poke about in wolf or coyote feces to find out what these predators ate. these feces are saturated with tiny, lightweight Echinococcus eggs that rise like dust plume from the disturbed feces and envelop the poking hunter. If the air-born eggs are ingested, the an infection is possible, and having Echinococcus cysts grow inside oneself is not a desirable condition. Trust me!

He followed that up with more information about the dangers.

As to the pathogenicity of Echinococcus granulosus: Yes, I noticed that Foayt, leaning on Raup’s research in Alaska, toned down the dangers from this northern form. My understanding based on what we learned from an old, experienced parasitologist at the University of British Columbia is that it’s nothing to fool around with. It’s serious! In my career as a biologist in touch with the north, I have heard nothing else. I have not, however, done a recent literature search. Foayte’s assessment may be on even though it conflicts with mine. Either way, getting an Echinococcus cyst of any kind is no laughing matter as it can grow not only on the liver or the lungs, but also in the brain. And then it’s fatal.

There is however, another much more alarming angle. Echinococcus multilocularis is a nightmare, and much more virulent than Echinococcus granulosus of any strain. We cannot encapsulate this cyst, and it grows and buds off like a cancer infecting different parts of the body incessantly. Were some of the wolves infected with multilocularis? Coyotes and foxes carry it and it has been spreading. Do canids in Idaho, Montana, etc. have it? It’s found in Alberta. Regardless, now is the time to send out an SOS to ALL outdoor users. Hold your curiosity in check, do not poke into the feces of wolves, coyotes and foxes. If you do you will release clouds of Echinococcus eggs which will envelop you, and you may ingest the eggs, bring the eggs home and endanger your family. This is nothing new to me and I have lived with this constraint on my curiosity for over 40 years. This is just a know how that maintains your personal and your family’s safety. Also, never feed uncooked offal to your dog as it may become infected with Echinococcus and infect you and your family. Echinococcus cysts love to be in lung and liver, and if consumed by dogs you have a health hazard on your hands. And such cysts now grow in deer and elk where you live. Somebody should take a second look searching out Echinococcus multilocularis.

You and I probably have no idea in the world whether these worms exist in the woods we hunt, trap, hike, etc. but good advice given by Dr. Geist should tell us it’s not something we should mess around with. Squelch the curiosity to dig in the poop and just assume there could be hidden danger.

I want to take a moment to thank Will Graves, Dr. Val Geist and Dr. Charles Kay for caring enough about the rest of us to be willing to share their findings and experiences.

To confirm the presence of the disease, blood and certain tissue has to be analyzed.

According to both the South Carolina Department of Natural Resources and the Alabama Department of Conservation, dealing with EHD is quite routine. Charles Ruth, Deer/Turkey Project supervisor for the South Carolina DNR says flair-ups in that state seem to run in cycles of 3-5 years and there’s a reasonable explanation.

“This is probably related to the fact that once deer are exposed to the disease they are more resistant to it. Therefore, if you have disease one year the deer become exposed or inoculated to the disease and you do not see much disease activity until there is turnover in the deer population. After several years you are dealing with another cohort of deer and their systems are ‘naïve’ to the disease. The last time there was significant hemorrhagic disease activity in South Carolina was in 2002, therefore, disease activity could be relatively high this year.”

This theory is confirmed by a spokesman for the Alabama Department of Conservation and Natural Resources.

“We have some cases every year,” said Keith Guyse, a whitetail specialist with the Wildlife and Freshwater Fisheries Division in the Alabama Department of Conservation and Natural Resources. “In the Coastal Plain, the virus is there frequently enough that deer have been exposed to it and have some resistance to it.

Both representatives indicate that EHD in their respective states is pretty much routine only because of the build up of a certain degree of immunity. Therefore, these southern states don’t see wide outbreaks of the disease that often. When EHD hits the more northern climes, EHD seems to grab harder. Ruth explains.

Deer likely die in South Carolina each year from hemorrhagic disease, however, there is no indication that a major outbreak has occurred in the state since the mid 1970s. The disease is part of life for deer in the Southeast and fortunately it appears that Southern deer have acquired some immunity to the disease, said Ruth. Northern deer, on the other hand, are not exposed to the disease as frequently since the insect vector is not as common in cooler climates. For this reason, significant outbreaks and mortality from hemorrhagic disease are more likely in northern deer populations.

Guyse from Alabama makes reference to the same theory.

“Typically in North Alabama and above the fall line, they’re not exposed to it as often. So over a period of time you have a population that doesn’t have much resistance. When you have (outbreaks) up there, it tends to be more noticeable.”

This helps us understand why some states may have more severe outbreaks, killing larger numbers of deer, than others but why this year are outbreaks so widespread across the landscape of the country? Some have related it to the summer heat and drought. That may be true, I don’t know. It would be logical to assume that being that the virus is carried and spread by tiny midges or gnats, a larger than normal population of that insect would be directly proportional to the spread of the disease. Of course science isn’t that simplistic and we know that there are probably many more factors to consider or it could be just merely a coincidence.

However, Guyse from Alabama eludes to the theory of increased numbers of midges, somewhat.

“Auburn (researchers) had traps out to catch the flies and they might catch a few every once in a while, and then all of a sudden they catch hundreds,” Guyse said. “Much of that still is a mystery.”

Obviously, they don’t have a good handle on it either.

Hunters and others should be aware of the symptoms they may find on deer suffering from the disease.

Symptoms of hemorrhagic disease include poor physical condition, sloughing hooves, abrasions or sores on the brisket and legs, and ulcerations on the mouth, tongue, and rumen (stomach).

As I said earlier, verification of the disease has to be done in the lab.

If you see sick or dead deer in your travels, please report it to the appropriate authorities. It is highly recommended that nobody eats any of the meat from deer sickened by EHD.

Fred J. Aun of the Star-Ledger, in reporting about the discovery of the disease in New Jersey, describes EHD this way.

EHD is not uncommon and it’s not dangerous to humans. It is caused by the bite of certain midges and results in high fevers and hemorrhages in the mouths, noses and eyes of deer prior to death. Fish and Wildlife said deer usually expire within 10 days of getting EHD.

Vice President of Global Operations for Skinny Moose Media and U.S. Hunting Today, John Stabley, called Dr. Colleen O’Keefe, IDOA division manager of Food Safety and Animal Protection, in Illinois to ask her specific questions about the disease, its affect on deer and other animals as well as humans. You can read the entire interview at Stabley’s blog, Stabley Outdoors.

J.R. Absher, the Newshound, has been keeping his readers abreast of the locations and severity of the disease.

In the meantime, as we hunters head into the woods to do our scouting or for the start of any of hunting seasons, keep an eye open for the possibility of EHD being present in deer. If you encounter any cases you are encouraged to contact your fish and game department with the information.

Yesterday I reported that EHD had been confirmed in Virginia, Kentucky, North Carolina, Tennessee and Alabama. Today, Pennsylvania officials report 100 deer found dead in the southwestern part of the state was due also to EHD.

Here’s a bit more information about EHD from the Indiana DNR website.

The disease is transmitted by biting insects called midges. EHD is not transmitted to humans and is not normally found in domestic animals, which generally contract a related disease commonly called Blue Tongue instead.

EHD poses no danger to humans from handling, processing or eating the meat of an exposed animal. Hunters should take normal precautions handling all deer. As always, deer meat should be thoroughly cooked to kill any bacteria present.

This disease should not be confused with the unrelated brain disease in deer, Chronic Wasting Disease (CWD), which has never been found in Indiana.

EHD causes severe, flulike symptoms, plus a high fever in deer, apparently causing those infected to seek open water to cool. Sick deer may lose their appetite, coordination and their fear of normal dangers. The animals become dehydrated and progressively weaker as the disease progresses, with mouth and eye tissue often showing a rosy or bluish color. A sick deer will be obvious to someone familiar with what a healthy deer looks like.

EHD is a common virus found in whitetail deer and will run its usual course until the first hard freeze, when insects that carry the disease will die off. It is not always fatal to the deer.
