What is the proper way to wash hands before handling food in a lab?

• A. Rinse with cold water only.
• B. Dry hands on a towel.
• C. Use sanitizer instead of washing.
• D. Wet hands, apply soap, scrub all surfaces for at least 20 seconds, rinse and dry.

Answer: (D)

Proper handwashing before handling food in a lab means removing germs with soap and water through thorough scrubbing for enough time. Start by wetting your hands, applying soap, and scrubbing all surfaces for at least 20 seconds, including backs of hands, between fingers, and under nails, then rinse well and dry completely. This routine physically lifts and carries away dirt and microbes so they don’t get onto food or surfaces. Rinsing with cold water alone won’t remove oils and germs, and using sanitizer instead of washing doesn’t reliably clean hands that are dirty or contaminated. Drying on a towel can spread germs, so use a clean towel or air-dry after washing.
