Which is not a way to prevent food-borne illnesses according to the dietary guidelines for Americans?

One way that is not recommended by the Dietary Guidelines for Americans to prevent food-borne illnesses is relying solely on washing food items before consumption, such as fruits and vegetables, without proper cooking or food handling practices. While washing is important, it should be part of a broader approach that includes cooking foods to safe temperatures, avoiding cross-contamination, and practicing good hygiene. It's essential to combine multiple food safety practices for effective prevention.
