What is the proper technique for handwashing?

1. Wipe hands with a damp cloth

2. Wet hands, apply soap, scrub for 20 seconds, rinse, and dry

3. Rinse hands under water for 10 seconds

4. Use hand sanitizer only

The correct answer is: Wet hands, apply soap, scrub for 20 seconds, rinse, and dry

The proper technique for handwashing is to wet the hands, apply soap, scrub for 20 seconds, rinse, and then dry. This method is essential because it effectively removes dirt, bacteria, and viruses from the hands, thereby reducing the risk of foodborne illnesses and contamination. Using soap is crucial because it breaks down the oils and dirt on the skin, allowing for better removal of germs when scrubbing. The 20-second scrubbing duration is recommended because it provides enough time to thoroughly clean all surfaces of the hands, including the back of the hands, between the fingers, and under the nails. Rinsing ensures that the soap and any dislodged contaminants are washed away. Finally, drying hands properly is important since wet or damp hands can transfer bacteria more easily than dry hands. The other methods listed do not effectively remove germs. Wiping hands with a damp cloth does not provide proper sanitation. Simply rinsing hands under water for 10 seconds is not sufficient to eliminate pathogens. Relying on hand sanitizer alone can be useful when soap and water are unavailable, but it should not replace proper handwashing, especially in food handling environments.
