Why are hand sanitizers not considered a replacement for hand washing?

Hand sanitizers are not considered a replacement for handwashing primarily because they do not effectively remove dirt and certain pathogens. While hand sanitizers can reduce the number of germs on hands, they do not remove physical debris, such as dirt, grease, and food particles. Additionally, some pathogens, particularly certain viruses and bacteria, may remain on the skin even after using hand sanitizer.

Handwashing with soap and water is far more effective in cleaning the hands, as it not only eliminates germs but also helps remove harmful substances and organic matter from the skin. This is particularly important in food handling and preparation environments where hygiene is critical for preventing contamination.

Using hand sanitizer is beneficial when soap and water are not available, but it should not be the primary method of hand hygiene, especially in scenarios where hands are visibly dirty or contaminated. This distinction is crucial in maintaining food safety and preventing foodborne illnesses.
