When are hand sanitizers effective in food handling?

1. As a substitute for handwashing

2. Always necessary after touching food

3. As a supplement to handwashing

4. Only when food is dry

The correct answer is: As a supplement to handwashing

Hand sanitizers are considered effective in food handling primarily as a supplement to handwashing. This means that while hand sanitizers can help reduce the number of germs on hands, they should not replace proper handwashing practices. Effective handwashing with soap and water removes dirt, grease, and a wide range of pathogens. Even if hand sanitizers are used afterward, they cannot effectively eliminate all types of pathogens, especially when hands are visibly dirty or greasy. Therefore, the best practice is to wash hands thoroughly and then use hand sanitizer for added protection against germs. In food handling, it's important to recognize that hand sanitizers can help in situations where washing hands isn't immediately possible; however, they should ideally follow proper handwashing. This includes scenarios where quick sanitation is necessary, such as between handling different types of food or after using the restroom, but they should not be seen as an alternative to the foundational practice of handwashing.
