What is the recommended time frame for refrigerating perishable leftovers?

The recommended time frame for refrigerating perishable leftovers is within 2 hours. This guideline is critical for food safety, as leaving perishable items at room temperature for too long can lead to the growth of harmful bacteria. The "2-hour rule" ensures that food does not reach a temperature that allows bacteria to thrive, which usually occurs when the food is between 40°F and 140°F (known as the danger zone).

Refrigerating leftovers promptly helps maintain their safety and quality, reducing the risk of foodborne illness. This rule is particularly important in cases of cooked meats, dairy products, and other perishable items that can spoil quickly if left out. Adhering to this time frame means that individuals can enjoy their leftovers safely while minimizing waste.
