Should hand sanitizers only be used before washing hands?

Hand sanitizers play a critical role in maintaining proper hygiene, particularly in food service and healthcare settings. They are designed to reduce the number of germs on hands when soap and water are not readily available. However, the optimal use of hand sanitizers is as a supplementary measure rather than a primary one.

Using hand sanitizers after washing hands can enhance cleanliness by removing any remaining pathogens. Washing hands thoroughly with soap and water removes dirt, grease, and organic material, making the application of hand sanitizer more effective. This dual approach ensures a higher level of sanitization, particularly before handling food or after activities that may compromise hygiene.

In situations where hands are not visibly soiled, hand sanitizer can be an effective alternative to washing hands. However, it's important to note that hand sanitizers should not be relied upon solely, especially in a food service environment. While they can reduce the presence of germs, they do not eliminate all types of pathogens and should not replace the practice of regular handwashing. This makes it clear why using hand sanitizers after proper handwashing, instead of only before, is crucial for effective hygiene management.
