Which of the following is not an example of good personal hygiene for food workers?

Using hand sanitizer before cooking is not considered a sufficient replacement for proper handwashing. While hand sanitizer can be a useful supplement in certain situations, it is important to understand that food workers should prioritize washing their hands with soap and water to effectively remove dirt, bacteria, and viruses.

Soap and water are effective at breaking down the oils and proteins that harbor pathogens, whereas hand sanitizer may not completely eliminate all types of germs, especially if hands are visibly dirty or greasy. Moreover, handwashing is critical in situations such as after using the restroom, before handling food, or when switching between tasks, which emphasizes the need for thorough hygiene practices.

In contrast, the other options are all examples of good personal hygiene practices. Frequent handwashing, double handwashing after restroom use, and washing hands with soap for a full 15 seconds are all essential for preventing foodborne illness and maintaining a safe food environment.
