The recommendation for employees to wash their hands for at least 20 seconds is supported by various health organizations, including the Centers for Disease Control and Prevention (CDC). Washing hands for this duration is effective in removing germs, dirt, and other contaminants that can be present on the skin. The action of scrubbing for 20 seconds helps to ensure that all surfaces of the hands are cleaned properly, including between the fingers and under the nails, which are areas where bacteria can easily hide.

Additionally, 20 seconds provides sufficient time to use soap effectively, creating a lather that aids in dislodging microbes from the skin. This guideline emphasizes not just the act of washing but also the thoroughness necessary to promote good hand hygiene and reduce the risk of transmitting illnesses. Consequently, adhering to this standard is particularly important in settings where food is prepared and served or in healthcare environments, where the potential for cross-contamination is higher.
