Hands must be washed thoroughly after handling raw food, using the restroom, and touching hair or face to maintain proper hygiene and prevent foodborne illnesses. Each of these activities has the potential to transfer harmful bacteria or contaminants to hands, which can then be transmitted to food or food-contact surfaces.

When handling raw food, especially meat, poultry, or seafood, it is crucial to wash hands to eliminate pathogens that may be present. This step is vital in preventing cross-contamination when preparing other foods.

Using the restroom is another critical time for handwashing, as hands can come into contact with a variety of pathogens found in fecal matter. Failing to wash hands after using the restroom can lead to the spread of germs.

Touching hair or face can also introduce contaminants to hands. Hair can carry oils and other substances, while touching the face can transfer bacteria from fingers, particularly if one has not washed hands after a potentially germ-laden activity.

Washing hands thoroughly after these activities promotes a safer food preparation environment, ensuring the health and safety of customers and employees alike.
