Final answer:
Ready-to-eat TCS food can be stored in a cooler for up to 7 days. Perishable foods must not stay in the temperature danger zone for over two hours to prevent foodborne illness. Rapid cooling techniques such as an ice water bath are crucial for safe food storage.
Step-by-step explanation:
Ready-to-eat TCS (Time/Temperature Control for Safety) food can be stored in a cooler for a maximum of 7 days, provided it is maintained at a temperature of 41 degrees Fahrenheit (5 degrees Celsius) or below. It is essential to ensure that perishable foods are not left at a temperature danger zone between 40 and 140 degrees Fahrenheit for more than two hours to prevent the proliferation of foodborne pathogens. Additionally, rapidly cooling foods like large quantities of soup is recommended by placing the pot in an ice water bath before refrigerating to bring down the temperature more quickly and safely.
