Experimental setup of the meat grinder testing in study of detection and decontamination of chronic wasting disease prions during venison processing. A) For negative control, surfaces were swabbed before use. B) Step 1: chronic wasting disease–negative or–positive muscle was passed through the grinder and surfaces swabbed. Step 2: grinders were disassembled and surfaces were cleaned/decontaminated. Step 3: grinder surfaces were swabbed again, and swabs were tested by real-time quaking-induced conversion.
