Final answer:
Ready-to-eat TCS food held over 24 hours has a shelf life of 3 to 7 days when stored at or below 41°F.
Step-by-step explanation:
Ready-to-eat Time/Temperature Control for Safety (TCS) food held over 24 hours should be stored at or below a temperature of 41°F (or 5°C). When stored at this temperature, the shelf life of the food can typically range from 3 to 7 days. It's important to note that while the bacteria growth is slowed down at lower temperatures, it doesn't completely stop, so it's still necessary to adhere to food safety guidelines and consume the food within the recommended shelf life.
