How should leftovers be stored to ensure safety?

Storing leftovers in shallow containers in the refrigerator is the best practice for ensuring safety. Shallow containers allow food to cool more quickly and evenly, which significantly reduces the time food spends in the temperature danger zone, where harmful bacteria can multiply rapidly.

When leftovers are stored in deep containers or at room temperature, they can take longer to cool down, creating ideal conditions for bacterial growth. Storing food in the pantry could lead to spoilage or foodborne illness, as most leftovers need to be refrigerated to remain safe for consumption. Additionally, heating leftovers in a microwave without covering them can lead to uneven heating, allowing parts of the food to remain at unsafe temperatures. Therefore, using shallow containers placed in the refrigerator is the most effective method for keeping leftovers safe.
