San Diego Food Handlers Practice Exam

Raw meats are most likely to cause cross-contamination due to the presence of harmful bacteria such as Salmonella, E. coli, and Listeria. These pathogens can be found on the surfaces of raw meat, and if proper handling practices are not followed, they can easily transfer to other foods, surfaces, utensils, or hands. This transfer happens through contact, splashing, or even through the use of unwashed cutting boards.

In food safety protocols, it is essential to keep raw meats separate from other food items to prevent the spread of these pathogens. This means using dedicated utensils and cutting boards for raw meats, thoroughly cleaning surfaces after handling, and storing raw meats securely in the refrigerator to avoid drips onto other foods.

In contrast, cooked rice, canned goods, and fresh fruits have much lower risks of harboring harmful pathogens that cause cross-contamination during normal preparation and handling. Cooked foods should remain uncontaminated if handled correctly, canned goods are sealed and less likely to carry bacteria, and fresh fruits usually carry a different profile of risks that can typically be managed by proper washing. Therefore, raw meats pose the highest risk for cross-contamination among the options listed.
