Final answer:
Counting trays should be wiped down after each use to prevent cross-contamination, aligning with the CDC's hand hygiene recommendations which also emphasize the importance of handwashing at key times and following five specific steps.
Step-by-step explanation:
Counting trays should be wiped down after each use. In environments such as healthcare settings and food preparation areas, cleanliness is paramount for preventing cross-contamination and maintaining health standards. Wiping down surfaces after use is a routine practice that aligns with the CDC recommendations for handwashing and hygiene, especially considering the times when hand hygiene is necessary, such as after handling objects, interacting with patients, or preparing food. Proper handwashing itself involves five key steps: wetting hands with clean, running water, lathering soap on every part of the hands, scrubbing for at least 20 seconds, rinsing well under clean running water, and finally, drying with a clean towel or air drying.
