Final answer:
Refrigerated food must be held at or below 40°F to prevent bacterial growth. If the temperature exceeds this for more than two hours, the food should not be consumed.
Step-by-step explanation:
All refrigerated food must be held at or below 40°F (4°C) to inhibit bacterial growth. If the temperature rises above 40°F for two hours or more, the food may no longer be safe and should be discarded. It's important to have a thermometer to monitor the refrigerator's temperature, especially during a power outage, to ensure food safety.
