CWD Study

Finally a bit of good news about CWD. A new study out of Wisconsin states that bleach will deactivate prions on stainless steel. Recommend soaking equipment in a 50/50 solution of bleach/water for an hour. Doesn't deactivate them on tissue though.

I have read that report. I'm still confused on it though, the one I've seen says 40% solution of bleach. Standard bleach we buy in grocery store is 5-6% sodium hypochlorite. Do they mean to dilute this 50/50 leaving 3-ish percent sodium hypochlorite or did they use a 40% sodium hypochlorite solution (something most regular folk can't get)?

I am skeptical as they have tried using bleach and fire on quarantined deer farms only to test the soil a year later and the prions were still active. I am still going to do what i am doing now. I soak my knife in bleach solution and place it in a ziploc back after its dried. If my results from my deer are positive the knife gets thrown away. This is why i bought a bunch of cheap knives off amazon.

All bleach concentrations tested are based on undiluted Purebright brand bleach considered as 100%, which contains 6% sodium hypochlorite.


After reading the whole paper rather than just the NIH news release it seems that regular bleach at the 6% that we can buy off the shelf is fine. There has been some good news recently on CWD.

With all the CWD they have up there thanks to Kroll & Scott Walker with the hunter popular "don't kill all the deer" approach, this is certainly good news for Wisconsin's.
