Which of the following is NOT one of the five steps in correctly washing hands in a sink?

The correct answer highlights an important aspect of effective hand washing. Rinsing with cold water is not recommended because warm water helps to remove soap and dirt more effectively, promoting better hygiene. When hands are rinsed with water that is at least 100°F, it aids in the overall cleaning process, allowing for a more thorough removal of germs and contaminants.

In contrast, scrubbing vigorously for 10-15 seconds and drying with a paper towel or air dryer are crucial components of the proper hand-washing technique. These steps ensure that any remaining germs are eliminated and that hands are completely dried, which further reduces the potential for contamination. Each of these practices is integral to maintaining good hygiene standards, particularly in food service and health-related environments.
