Bad News for Deer Hunters: CWD in 2 Men

HB: that very thing happened in Florida with screw worm infestations...........old timers that participated said they were paid a few dollars a deer tail 20's & 30's time period.
But releasing irradiated screw worm males that were impotent is what eliminated the screw worm from Florida in the '50s. Before that thousands of calves were lost due to screw worms annually. Until the 1950s Florida had open range ... no fences. Travelers on the roads were expected to yield to cows.

Cattle and citrus were the main industries until Disney spoiled it all. Pre-Disney, Kissimmee was a "cow town" home to the Silver Spurs Rodeo, the year's biggest attraction. Now Kissimmee is an abomination IMO.

Yes, there are very important words used in this article: "might have"

"that long-discussed and frequently dreaded transmission of CWD from hunter-harvested deer into human beings might have actually occurred in 2022."

Well I might have won the lottery in 2022. But in fact, I did not.😎
 
I just saw this and am passing it on to THR hunters.


Two men have died after eating CWD infected deer. Results inconclusive at present.

I agree. "Conservatives are BAD; Liberals are good" according to 80% of news organizations.
 
The thing hunters need to really ponder is if CWD jumps to livestock. Deer will get culled by the millions if it can be proven to infect cattle.

For sure.....and I would think that the crossover to another Bovine would be more probable than to a human.....at least at first. Just as scarey, would be if BSE(Mad Cow disease) would cross over to deer from cattle. Since it has been shown that BSE can migrate to humans from consumption of infected animals, it would be the end of deer and deer hunting as we know it. When CWD was first discovered in Wisconsin back in 2002, the DNR's goal was to kill every deer in the affected area. Deer season ran from August to March and you could shoot all you wanted to in the designated area. Still, deer kill was about the same as normal, because most of the area was private land where hunters dictated how many deer were shot. But, what you did see was hunters that were worried either quit hunting deer or gave the meat away to food pantries(wasn't that nice of them?:uhoh:). As the scare wore off, deer hunting went back to normal in the area.

hunted in CWD containment zones and never killed an infected deer. I have also eaten plenty I haven’t got tested. I still think Lyme is the scariest thing in the woods.
I hunt in CWD areas also.....have for years. Some deer I kill get tested, some don't. Butcher my own and the carcasses get properly disposed of. Have had Lyme twice and it is scary. Ticks this Spring are terribly thick because of the record warmth in February. Be interesting to see how the deer fare with them this year. At 70, I don't really worry about myself, as for the future of CWD, but I do worry about my grandkids who eat a lot of venison.

Very interesting. They cite the Mayo clinic for already noting CJD crossing species from cattle to humans.
Iffin' I remember correctly, Classic CJD is a human prion disease and is not related to BSE. The Variant CJD is what it is called when the BSE crosses over. Like CWD all are always fatal and all are widely misunderstood. Problem with all, is the sometimes very long incubation period once infected. We are talking years in many cases. It was once thought that it took at least 16-18 months for the disease to advance in whitetail deer once infected. Testing of fawns has now suggested that fanws as early as 5-6 months have the Prion in their system although it has not developed. It is not known if the disease was transmitted normally or in-otero during pregnancy.

As deer hunters, we need to make a concerted effort to help our state agencies delegated to CWD studies. In the same sense, those same agencies to to help us hunters, both with easier, quicker and free testing, and with giving us the most up to date information they have on the disease and it's spread. While Wisconsin has done a great job of trtying to inform, not all hunters pay attention, nor do they give a crap. Some don't want to know. Some believe it's all a big lie or a conspriacy to get rid of deer hunting. Idiots do not reralize the economic impact it would have on our state. No way any state agengy would bring that about on purpose, unless it was absolutely neccesary. most of the info out there is not driven by anit-hunters, but by hunters themselves. What our state is lacking is a better system for testing deer shot, especially by early and late season archers. Last year I used one of these....but it is pricey. Can't believe the state cannot add a small charge to the deer license and provide these for free upon registration. It would be great to be able to test deer already processed when shot in weather that did not permit the hunter to wait for test results.

CWD TEST
 
Monkeys are not humans, but this article is still interesting. Apparently there have been studies showing the transmission of CWD to monkeys who consumed venison from a CWD infected deer, even before the deer was showing symptoms.
"...CWD was transmitted to monkeys that were fed infected meat (muscle tissue) or brain tissue from CWD-infected deer and elk. Some of the meat came from asymptomatic deer that had CWD (i.e., deer that appeared healthy and had not begun to show signs of the illness yet). Meat from these asymptomatic deer was also able to infect the monkeys with CWD. "

I had been thinking that this was likely only transmitted by tissue from the central nervous system of an infected deer, but apparently (at least in the case of the monkeys used in the test) that is not true.

Cooking does not inactivate CWD prions and the amount of heat required to render the prions safe is sufficient to destroy the meat and even most items one might want to decontaminate. Based on one source, it does appear that one can inactivate the CWD prions by soaking an infected item in a 40% bleach solution for 5 minutes.

Since from what I have read, the monkeys were fed both muscle and brain tissue, I too believe it was the CNS tissue that was the culprit. same reason most DNR/F&G agencies recommend not eating anything from the CNS, to avoid shooting animals in the CNS, to not eat meat surrounding any damaged CNS and to not handle any CNS material without rubber gloves and tools that can be disposed of properly. This includes the cutting off the head and sawing off antlers.
Based on one source, it does appear that one can inactivate the CWD prions by soaking an infected item in a 40% bleach solution for 5 minutes.

My understanding is this has been proven to only work on metal, such as butchering and taxidermy tools. It has not been proven to work on things like wooden cutting boards, or even the tiniest pieces of tissue left on those tools. I butcher my own deer and do bleach all my knives after use. I use rubber gloves and a fresh piece of plywood for a cutting board. The gloves and cutting board are disposed of along with the carcass and trimmings at a local landfill that has been approved for accepting deer waste.

Threads like this, IMHO, are a very good tool to get information out to those that may not be as informed as they should be. But it is only good as long as the information is correct. What I have seen in the past from many folks is the passing along of "what they heard" and is not always factual or the truth. Our DNR has a wealth of info available out there for those who want to know the latest info on a subject that is constantly changing. Like with Covid, folks over reacted at first when CWD was discovered here, but now it seems the general opinion from most hunters, is a mild "meh". Most don't know how, nor do they care, how to properly field dress, process and dispose of the deer they shoot, to help reduce their exposure and the spread of CWD. The elimination of registering deer at a station means most don't bother to have their deer tested. If a test packet similar to like I posted above, was included with a deer license, or readily available locally for a good price, it would mean at least they don't have an excuse to not get their deer tested.
 
Since from what I have read, the monkeys were fed both muscle and brain tissue, I too believe it was the CNS tissue that was the culprit.
Unfortunately it does not say that they were fed both.

"...CWD was transmitted to monkeys that were fed infected meat (muscle tissue) or brain tissue from CWD-infected deer and elk."

"Meat from these asymptomatic deer was also able to infect the monkeys with CWD."

The wording of the article clearly indicates that both CNS tissue and meat were able to infect the monkeys.

It does indicate that a previous study did not find that particular type of monkey could be infected with CWD and that currently there is no explanation for why the results of the two studies differ.
My understanding is this has been proven to only work on metal, such as butchering and taxidermy tools.
Correct. The source I found indicated that they were doing their testing "disinfecting" stainless steel objects. The only way to deal with tissue that I could find is to burn it at high temperature.
 
We have it here (Montana). From what I understand is it’s in the spinal fluid and brain. Me and my two sons get deer and antelope every year plus an occasional elk. I don’t test them and we cook the meat thoroughly.

It’s been said multiple times in this thread and I just want to emphasize. YOU CAN NOT KILL PRIONS BY COOKING YOUR MEAT WELL DONE!

The heat required to kill a prion is hot enough that your meat will be ashes before the prion is destroyed. A prion is a protein not a virus, fungus or bacteria.
 
I had a gal at work back around 2002 tell me of two deer hunters that supposedly got CJD.
The two guys hunted together.

Her father had CJD and she was researching it.

That probably a different incident. Dunno what was proved/disproved.

Correct. Because you can not kill them at all. They are not alive.
I too believe it was the CNS tissue that was the culprit.
I was able to find some more information on the study with the macaques and it is disturbing.

https://vkm.no/download/18.25950e0715e84a118a6ec492/1506925175221/Statement CWD.pdf

"Two of the animals that were orally infected (AU501, AU385) developed ataxia, tremor, apathy and wasting to varying degrees and initially very subtle. These two animals had been fed raw meat from white tailed deer that were in the preclinical stage of CWD."​

This means that the animals ate CWD infected meat (not CNS tissue) and became infected from it. What's worse is that the deer that the meat came from were not yet showing symptoms.

You can read the article. They discuss the fact that a previous study showed NO infection in macaques from CWD infected meat or CNS tissue. Because they have not provided a good reason for the disparity in the results, and because this is a study on macaques, not humans, I don't believe that we can call this one conclusive, but it is concerning.

I think that caution is warranted at this point. If you live in an area where CWD is common (you decide what 'common' means since you're the one taking the risk) then you need to be aware that if this study is correct and if it applies to humans and not just macaque monkeys, there is no way to protect yourself from CWD other than not eating meat from any animals which can be infected--that includes deer, elk, moose, etc.
  • Trying to avoid animals that look sick does not appear to be effective.
  • Trying to avoid CNS tissue does not appear to be effective.
  • Cooking the meat thoroughly will not eliminate the infectious agent.

Kinda the point many have been trying to make for years......yet so many don't want to hear it. This is serious, while many just blow it off. The idea that muscle tissue will infect just as easily as CNS tissue is disturbing, but even more disturbing from what I got from your link, is the fact that those monkeys were infected for 5-6 years and showed no ill health. This means we could already have millions of hunters/folks who eat venison, infected and not know it, till at some point, folks start dying.
 
...those monkeys were infected for 5-6 years and showed no ill health.
Right. Long "incubation" periods are kind of a hallmark of the prion diseases. Actually, as far as that goes, 5-6 years is pretty short. What I liked the least from the study was that the deer meat that infected the monkeys came from deer that tested positive for CWD but that were not showing any symptoms yet.

It does appear that there is work being done on a vaccine and progress is being made, but it looks like there's a lot of work to be done still.
 
Another update:


CDC: Deer meat did not lead to hunters' illnesses, death​

About the 2022 report, the agency agreed with the researchers "that there is a need for careful investigation of chronic wasting disease (CWD) as a potential risk to people's’ health," CDC epidemiologist Ryan Maddox said in a statement to USA TODAY.

But the CDC reviewed the 2022 cases and considered the two men's deaths as "part of the normal number of cases of CJD (Creutzfeldt-Jakob disease) we see in the U.S.," he said.

The men died after developing Creutzfeldt-Jakob disease (CJD), which like CWD is a prion disease, a class of fatal neurological disorders, which can affect humans and animals, and usually progress rapidly and are always fatal. In prion diseases, certain proteins in the brain begin to fold abnormally, causing brain damage and other symptoms, the CDC says.

"A history of hunting and/or eating venison does not mean that someone got CJD that way," Maddox said. "Many Americans hunt and even more eat venison. Some will develop sporadic CJD by chance and others will not."
 
I live where CWD mulies are a possibility. We kill healthy looking deer and I’ve never seen one that appeared sick with the disease based on their behavior.

Could it infect myself or my family, yes it’s a remote possibility. Same can be said of beef, and the sheer number of animals thrown into a “grind pile” for burger meat seems to statistically up the chances.

We live in a fallen world filled with risks and consequences. Yesterday I took a 12yo and an 8yo sledding at a local ski resort. Dangerous, yes, but we took steps to mitigate the risk and they won’t soon forget the experience.

Yep, here's another link to a different article in USA Today, basically same story.

From the article:

“And ongoing studies do not show an increase in rates of CJD in hunters in Colorado. "Results so far have been reassuring," he said. "The number of cases of CJD or other prion disease in this hunting population has not been higher than what we would expect in the general population."

Folks, go hunt and enjoy your venison.
