Chronic wasting disease is continuing to pop up in deer and elk populations around the Mountain West. But researchers have found one way to help prevent hunters from further spreading the neurodegenerative disease: household bleach.
All it takes is five minutes of soaking in a solution of 40% bleach and your hunting knife — and other metal meat-processing tools — will be disinfected, according to a new study published in the scientific journal PLOS One.
"This is good news for people who want to be extra cautious," said Brent Race, who led the study. Race is a staff scientist at Montana's Rocky Mountain Laboratories, which is part of the National Institutes of Health.
Hunters need not lug buckets and bleach wherever they go, Race says, but if after butchering an animal it tests positive for CWD, "I'd certainly be going back and bleaching everything that I could that had contact with that animal."
Bleach can't disinfect actual bits of tissue, though.
While there have been no reported cases of CWD infection in people, the disease has the potential to cross the species barrier. The Centers for Disease Control and Prevention recommends not eating meat from a CWD-positive animal.
