Washing hands frequently is a crucial food safety measure to prevent cross-contamination because it helps remove pathogens that can be transferred from hands to food or food-contact surfaces. Hands can easily carry bacteria, viruses, and other contaminants after handling raw foods, touching surfaces, or even after using the restroom. Regular handwashing with soap and water, especially before and after handling different food items, is essential in maintaining hygiene and reducing the risk of foodborne illnesses.

The other options would not effectively prevent cross-contamination. Using the same cutting board for all foods can lead to the transfer of harmful pathogens from raw foods to ready-to-eat items. Cooking food to different temperatures does not address cross-contamination during preparation and can still leave food vulnerable if handled improperly. Storing raw foods on the top shelf can lead to drips and splatters contaminating foods stored below. Proper handwashing creates a foundational practice that is vital for safe food handling.
