What is an essential step when storing leftover food?

Placing leftover food in a shallow container is essential because it promotes even and efficient cooling. Shallow containers allow heat to dissipate more quickly, which is crucial in preventing the growth of bacteria. When food is stored in deep containers, it can take a long time for the food at the center to cool down, increasing the risk of bacterial growth as it remains in the temperature danger zone (between 40°F and 140°F) for too long.

In addition to ensuring safety by cooling food faster, shallow containers also make it easier to reheat portions uniformly when it's time to consume the leftovers again. It's important for food safety practices to utilize appropriate storage techniques, and using shallow containers aligns with these principles by minimizing the risk of foodborne illnesses.
