Experimental design of knife and cutting board 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 chronic wasting disease–positive muscle was cut and surfaces were swabbed. Step 2: surfaces were cleaned. Step 3: surfaces were swabbed again and swabs were tested by real-time quaking-induced conversion. Figure created using BioRender (https://www.biorender.com).
