Lets talk CWD

[Andy S.]

Good read Patrick, thanks for taking the time to type all of that.

Very good read.

The comments about contaminated knives, what should one do if they gut and debone and deer and have it tested and it tests positive. Should that equipment be replaced so as not to transfer prions to a clean deer?

I can't comprehend how equipment couldn't be sanitized but from what I read said there was no way to sanitize tainted equipment.

GREAT & INSIGHTFUL POST!
Thank You for sharing this info!

Regarding the venison consumption,
I was thinking similarly, but certainly
couldn't put the thoughts into words so eloquently!

All that said my final thought- there is risk in everything we eat.
Salmonella, e. Coli, pesticides, chemicals and hormones.
Considering the totality of scientific data,
venison appears to be a safe, healthy choice for the dinner table, even in states where CWD is prevalent.

TOTALLY AGREE!

Excellent information.

I'm not aware of any specific studies that have tested the destruction of CWD specific prions. I know that prions are known to have survived lower temperature autoclave on surgical instruments, and subsequently infected patients.

Basically prions are proteins that fold normal proteins into more prions. They are misfolded in a way that makes them difficult to unfold. Normally, heat will cause proteins to unfold, but the structure of prions are pretty resistant to this (and other things, like bleach and peptides).

Yes, heat will destroy prions. But boiling isn't hot enough. You have to incinerate them - basically turn them into carbon. So The short answer is, yes you can incinerate prions. You just have to get whatever you are sterilizing hot enough, and how hot are you gonna be able to get a wooden or rubber handled knife before you burn it up or melt it. This is the problem. Yes, you can destroy prions on a scalpel, or a screw. But much harder to do that on a endoscopic camera. Or - a non medical example - a pasture where cows have grazed.

What would be recommended for knives that deboned or gutted a deer and that deer was found to test positive?

Should you get rid of it or just clean like normal and continue to use?

Considering that we don't think CWD is human transmissible, I suppose you could just wash it off and keep going.

Hot water and soap won't kill the prions but it may wash them off.

If it were me I would probably be getting a new knife. I don't know if cutting yourself and directly inoculating the prions in your body would make a difference

Thanks. So dont use my favorite knife working up deer anymore. Thankfully I'm not in the "hot zone", I'm just east of TN river....but I'm sure its just a matter of time.

This might be a dumb question.
Say you have a cut on your hand.You think it would be wise to wear rubber gloves when you gut a deer?

Im not a medical expert, but the CDC recommends wearing gloves when skinning and processing wild game.

I dont know if having a cut makes you more susceptible to CWD, but it certainly can't help.

I use them anyway while cutting up a deer . Great read docpoco or Patrick thanks for sharing .

Good read

Almost what the fellow from Nebraska told me word for word. In short, wasn't an issue when talking about herd loss.

vCJD is very rare, and those in England who have died from it has been tied to their particular genetic makeup. the 4 cases in the US previously lived in the UK and Saudi. the one known case in the US possibly got it from eating squirrel brains and possibly a dozen others in Kentucky 20 years ago. ive eaten squirrel brains since i was a kid but stopped after i heard about the guys in Kentucky. im still alive and well.

all mammals has the ability to produce the proteins, even humans. i imagine it has always been here just like anthrax in the soil in Texas from the centuries of cattle raising. i imagine some of us even have the mishappened prions in our bodies already. 1 in 2000 is estimated to have it in the UK. another factoid, out of the 223 that have died from vCJD all were born before 1989.

the biggest thing is not to panic, take precautions to keep if from spreading.

it would be cool if we could find a testing lab that could test our kills, if it is not horribly expensive.

Very informative. Really appreciate how readable and understandable all that was. Thank you. Any recommendations on further reading on how all this got started?

Thanks. Haven't seen anything about freezing. Same as heat?

 

[Cold Tree]

Assuming freezing is useless?

I wonder if a business could be started testing for this,maybe charge $20

Thanks for posting , good info.

Thank you for posting that. I believe one problem with the spread of the disease is the unknown incubation period. From my education, at the time they were unable to establish a consistent time from exposure to becoming symptomatic. Thus, making it even more difficult to control the spread. Please correct me if you have more current info

Good stuff and a great start for anyone. The literature available is very interesting and plenty of it to read. Lots of podcast available as well if you prefer to listen, Joe Rogan and Meateater are two that have great CWD topics.

What concerns me about the TN discovery is the number of deer that suddenly tested positive, once we find out the sample size I will either be relived or....

10 positive in 1 small area would indicate it's been there for at least a few years. The deer in North Ms was likely infected by the TN herd, not the other way around.

Soaking contaminated equipment in pure bleach for 1 hour will sterilize it. May ruin the edge on your knife however

You said that the protein will unfold when heated.Maybe that is the time to try a chemical bath or other sources to kill it.Or is the point of unfolding just to hot.Or does it unfold at a much lower temp.I'm just assuming that the point of the unfold is the chance to destroy it.If you can destroy it or even change it's shape it would not fit in the puzzle of sorts and be rejected VS absorbed.
