What is the correct procedure for handwashing?

The correct procedure for handwashing is to wet hands with water, apply soap, scrub for at least 20 seconds, rinse, and dry. This method is effective because it incorporates several key components that ensure thorough cleaning and the removal of pathogens.

First, wetting the hands with water helps to activate the soap, making it more effective at breaking down dirt and germs. The application of soap is crucial because it helps to lift and remove contaminants from the skin's surface. Scrubbing for at least 20 seconds is recommended because it provides enough time for the soap to do its job—mechanically removing dirt and detaching germs from the skin. This thorough scrubbing also ensures that all areas of the hands, including between the fingers and under the nails, are cleaned. Rinsing off the soap and any loosened debris is the final step that completes the handwashing process. Finally, drying the hands—preferably with a clean towel or air dryer—prevents recontamination, as wet hands can transfer germs more easily.

The other options do not meet the established handwashing guidelines. They either do not include soap or insufficient scrubbing time, which reduces the effectiveness of removing harmful microorganisms. Therefore, following this procedure significantly contributes to food safety
