How often should hand sanitizers be used?

Using hand sanitizers is most effective when there is no access to soap and water, making the correct option about their use situational. Hand sanitizers are beneficial for killing germs and reducing the spread of pathogens, but they do not eliminate all types of germs and may not remove dirt or food particles that soap and water can wash away.

Handwashing with soap and water is the preferred method for cleaning hands, especially after handling food, using the restroom, or when hands are visibly soiled. While hand sanitizers can complement hand hygiene practices, they should not be considered a replacement for handwashing. Therefore, they should be used in circumstances where handwashing is not immediately possible, providing a critical line of defense in food safety and sanitation.
