What is the required time for proper hand washing?

The required time for proper hand washing is 20 seconds. This duration is based on guidelines provided by health organizations to ensure that all surfaces of the hands are thoroughly cleaned. Washing hands for at least 20 seconds helps remove dirt, bacteria, and viruses, thereby reducing the risk of transmitting infections, especially in food preparation areas like a deli.

During this time, it is crucial to scrub all parts of the hands, including the back of the hands, between the fingers, and under the nails, as these areas can harbor germs. The emphasis on 20 seconds aligns with recommendations from health authorities who advocate for effective hygiene practices. Using a timer or singing a song that lasts about this duration can help ensure that individuals wash their hands for the appropriate length of time.
