To wash hands correctly, a food handler must first?

To wash hands correctly, the first step is to wet hands and arms. This foundational step is crucial because it helps to prepare the skin to effectively remove dirt, food particles, and pathogens. By wetting the hands and arms, the soap can create an emulsion that lifts bacteria and contaminants off the skin when it is applied.

Starting with wet hands ensures that the soap can spread more efficiently during the washing process. It also activates the cleaning agents in the soap, allowing for a more thorough cleaning. Once the hands are adequately wet, the user can then apply soap, scrub rigorously, and rinse thoroughly to complete the handwashing process effectively.
