Household bleach inactivates chronic wasting disease prions

A 5-minute soak in a 40% solution of household bleach decontaminated stainless steel wires coated with chronic wasting disease (CWD) prions, according to a new study by National Institutes of Health scientists. The scientists used the wires to model knives and saws that hunters and meat processors use when handling deer, elk and moose—all of which are susceptible to CWD. The research was conducted at Rocky Mountain Laboratories (RML) in Hamilton, Mont. RML is a component of the NIH's National Institute of Allergy and Infectious Diseases. The findings are published in the open-access journal PLOS One.
