This study says bleach does fine with a couple minutes exposure.

Inactivation of chronic wasting disease prions using sodium hypochlorite - PMC

Chronic wasting disease (CWD) is a fatal prion disease that can infect deer, elk and moose. CWD has now been detected in 26 states of the USA, 3 Canadian provinces, South Korea, Norway, Sweden and Finland. CWD continues to spread from endemic areas, ...

This is correct, bleach kills the prions.

Good lord folks get some facts.
Dementia is not CJD. Variant CJD is the one that some feel is related to CWD but has not been proven yet, it manifests most closely with cwd.
Dementia and CJD are very different illnesses.

As to date there have been no species barrier crossing with cwd unless injected right into brain tissue- yes that monkey study was injected cwd prions. That means one animal giving it to another animal species.

If your family shows signs of variant CJD they most certainly test for it and keep track of cases throughout the country.

Yes I've had a positive and it was healthy looking and we ate it. We hunt in the endemic area in Wyoming and rarely get our animals tested unless mandated or they look unhealthy.
Be very clean gutting and processing, avoid spinal fluids, brain matter etc and you should be good. Might avoid lymph nodes since they test those now too.


Would I feed it to my kids or give meat to anyone without them knowing about it, no.

No one said that CWD was CJD.

We shoot a lot of positive deer here in WI. The general consensus among the people I know is not to eat it or feed it to family/friends. It totally sucks but isn’t worth the risk. Humans have a long lifespan—time will tell what happens…

Prion disease is found in multiple species, ungulates have CWD, sheep scrapie, cows mad cow and humans cjd. CJD is an occupational hazard for neurosurgeons presumably from direct exposure. Friends father was dxd with CJD, raised and butchered sheep and family presumes thats what he had but to my knowledge direct interspecies transmission has not been confirmed. Diagnosis in the past required brain biopsy in humans, interesting that ungulate tissue sampling is retropharyngeal lymph nodes, not neural tissue. Prions are found in soil and may be how grazing animals contract it vs direct animal to animal transmission. Whenever I remove a head from an animal all tools have a bleach bath and always wear gloves. Deboning meat may bring you in contact with neural tissue and lymph nodes, take care.

Interspecies transmission of prions - PubMed

Mammalian prions are infectious agents of proteinaceous nature that cause several incurable neurodegenerative diseases. Interspecies transmission of prions is usually impeded or impossible. Barriers in prion transmission are caused by small interspecies differences in the primary structure of...

Recognizing that the CDC is not considered the reliable fact based agency it was in the past, these are the current diagnostic criteria in humans, notice nothing about lymph node biopsy.

Diagnostic Criteria | Creutzfeldt-Jakob Disease, Classic (CJD) | Prion Disease | CDC

Lastly, you don’t know what you don’t know. If CJD isn’t considered or within the knowledge realm of a practitioner the diagnosis will never be made. Almost certainly people have died from CJD that were considered a non specific neurodegenerative disease.

This is not correct, “Bleach isn't the cure-all for CWD. It only works on nonporous surfaces, but it's the first thing scientists have discovered that inactivates the abnormal prion that's wreaking havoc on cervid herds.” Another article :
The researchers worked with CWD-infected brains from white-tailed and mule deer. They tested various bleach concentrations and soak times to determine the most effective combination to eliminate prion seeding. Notably, the study failed to find an effective method to decontaminate CWD-infected solid tissue. Pieces of CWD-infected brain retained prion activity even after a 30-minute soak in 100% bleach. Investigators note that bleach fails to penetrate tissues and should be used only as a surface decontaminant.
The scientists hope that public health and wildlife agencies will consider this study when making formal recommendations for decontamination of CWD prions.
I was told by the biologist I talked to about it, the only sure way is to dispose of any thing used to “handle” and process the animal. Cutting boards, paper, tape, rags and highly suggested knives also. As the prions fit in the pores of the steal.
And as far as testing for JCD or similar after a persons passing, when we asked for it to be included in the autopsy, both doctors reply was if they were in there forties or younger they would have considered it. But not any older then that.

It’s been around since the 60’s if some one was getting it would have happened. Just another way for “science “ to make money.

*face-palm
Let's get a few things straight here. It can't be proven that at this point no one has contracted a Transmissible Spongiform Encephalopathy (TSE) from consuming a cwd positive cervid. Just because medical professionals haven't caught it, or haven't identified it, doesn't mean that it hasn't happened.
Is it likely to happen? Probably not. Is it possible? Absolutely.

There have been tests that have shown definitively that primates can contract cwd. It took a round about method, (prions introduced directly to nervous/brain tissue for the first positives and then cwd positive macaque meat fed to other macaques produced more positives IIRC). Its been a while since I read that study, so hopefully I've remembered correctly.

Prions, like any other replicating structure, can and do mutate. All it takes is the right mutation or an individual with the right genotype to be susceptible where the bulk of the human population is not.

Who the heck wants to be the first human with a TSE from eating venison that they know is CWD positive? I really enjoy venison, but not enough to knowingly consume a cwd positive animal.

Everyone gets to make the choice for themselves. The best anyone can do is make an informed choice based level of risk that they're willing to accept. After all, there's risk in everything we do.

I have everything tested. I've been keeping track since college in the 90s when I wrote paper on CWD for my Mammalian Physiology class. Am I an expert? No, but I do try to stay informed. TSE and it's related symptoms would be a particularly horrible way to go.

Well, I've processed all my game animals since, well, forever. I've never had a butcher shop process any ( don't trust them).
Been boning and cutting and grinding them over 60 years, the last 35 in an area of Montana that has supposedly high number of cases. Probably over a hundred deer anyway. The kids were raised on game.

Never worn gloves doing it. Never had any tested. So, I've never shot or eaten any animal that tested positive.

Do as you please, just dont forget to mask up, social distance wear a helmet and get your latest vaccine booster!

Every one gets a choice as long as they told about it. If your eating some that a buddy says he tested ( but like the guy above, some times don’t). Or feeding it to young ones that have no clue, choice. And how do they know the effects it would have on humans, never having tested for it. And iam with you, no way I am feeding it to my family, nor any body else. Hell I won’t feed it to any dogs.

mt terry d, We now know how you feel about your family. Sorry I won’t do that to mine. Maybe have them run back and forth across the highway every day too. Odds are they will be fine.

So has any one been confirmed to get . Yes or no. It’s been in game from before they even knew what it was when people ate the brains and all. So I guess i will take my chances. Ehd and blue tongue are an actual problem that kills way more deer.

If it’s that big of deal why do you even hunt?

I have always had every thing tested, and until now haven’t had an issue. And yes this will weigh in on future hunts for sure. I have already started to concentrate more on birds, and antelope. It would be nice if they had an infield test, you could do immediately after the kill. Would save a whole lot of work ( packing out, processing, and money, and then having to throw all the packaged meat, cutting boards, and all away now. Pain in the $&7.

Totally agree but an infield test would seem to bring in a lot of potential issues. I could see that being abused by some less scrupulous hunters. The test would also have to be 100% foolproof and no false positives.

 

[def90]

Well there hasn’t been any thing proven, but they have never tested a human for CWD either, so there’s that. We wanted my mom and father in law tested, and the hospital docs had no clue what we were asking. There is no test available, so we were told , on both accounts. Both were just “ diagnosed “ with dementia.

Creutzfeldt-Jakob Disease is the human equivalent to CWD. CJD does cause rapid onset of dementia while regular old alheimers and dementia progress at a slow and steady pace. I believe CJD can only be tested for after death. Mad Cow produces a variant of CJD. The rate of CJD cases has not increased statistically since it was discovered so one can infer that CWD has not crossed over at this point.

A lot of birds have had avian influenza and that has crossed to humans .

 

[Binz17]

I hunt whitetail in a cwd County in IL. They only test the gun season deer. Never had a positive test, but most of my deer are archery kills, so who knows? Have had multiple buddies deer test positive with those deer consumed by them. Nobody gone crazy yet. My family eats all the deer with no tests. I guess I'll get back to you if we start getting sick.

There is an article linked above citing a well known study stating clearly that a 40% solution of bleach will deactivate prions on solid surfaces like knives. Who on earth would care if bleach killed prions on flesh, what purpose would that serve?

You couldn't find a place to get a deer tested in Oklahoma even if you thought it was necessary.
The vet school at Oklahoma State might be able to but they sure don't publicize it.

Well no, no confirmed cases. They don’t test any humans for it. If there is no way to test for it, of course there are none.
