    **Potentially Hazardous Foods Requiring Temperature Control** Potentially hazardous foods (PHFs) are those that support the rapid growth of harmful bacteria if not stored or handled properly. These foods require strict temperature control to prevent foodborne illnesses. Common examples include: – **Meat and Poultry:** Raw and cooked beef, pork, chicken, and turkey must be kept at safe temperatures to inhibit bacterial growth. – **Seafood:** Fish, shellfish, and other seafood are highly perishable and need refrigeration or freezing. – **Dairy Products:** Milk, cheese, yogurt, and other dairy items must be stored at appropriate temperatures to maintain safety and quality. – **Eggs:** Both raw and cooked eggs require temperature control to prevent contamination. – **Cooked Rice and Pasta:** These starchy foods can harbor bacteria if left at room temperature. – **Cut Fruits and Vegetables:** Once peeled or cut, these foods become more susceptible to bacterial growth. – **Prepared Foods:** Any cooked or ready-to-eat foods that contain these ingredients also need temperature control. Maintaining proper temperature—typically below 41°F (5°C) for refrigeration and above 135°F (57°C) for hot holding—is essential to keep these foods safe for consumption.
