How long should the overall duration of handwashing be?

10 seconds
20 seconds
30 seconds
15 seconds

The correct answer is: 20 seconds

The recommended overall duration of handwashing is 20 seconds. This duration is important because it allows enough time to effectively remove dirt, debris, and pathogens from the hands. Research and guidelines from health organizations suggest that washing hands for at least 20 seconds significantly increases the effectiveness of this practice, helping to prevent the spread of infectious diseases. During this time, it is essential to thoroughly scrub all parts of the hands, including between the fingers and under the nails, to ensure that all surfaces are cleaned. By adhering to the 20-second guideline, individuals can provide a more thorough cleanse, reducing the likelihood of contamination in food safety contexts and promoting better overall public health.
