Which of the following is considered a potentially hazardous food (PHF)?

Cooked beans are considered a potentially hazardous food (PHF) because they are cooked and can support the growth of pathogenic microorganisms if they are not handled and stored properly. When cooked beans are left at room temperature for too long, or if they are not stored at the correct temperature, harmful bacteria can multiply, posing a risk to food safety.

In contrast, fresh milk, while it can be a PHF if not properly managed, is typically treated through pasteurization to kill harmful bacteria and then can be stored appropriately in refrigeration, making it less of a direct risk if properly handled. Granola bars, particularly when dry, do not provide an environment conducive to bacterial growth and thus are not classified as PHF. Frozen fruits, being frozen, are in a state that inhibits bacterial growth as well, therefore minimizing their risk as a potentially hazardous food.
