What is the best way to store leftovers?

Storing leftovers in an airtight container in the refrigerator is the best practice because it significantly reduces the risk of bacterial growth and food spoilage.

When leftovers are stored in an airtight container, they are protected from exposure to air, which can lead to oxidation and drying out of the food. Additionally, this method helps to contain moisture, preventing the food from becoming either too dry or soggy. Refrigeration further slows the growth of bacteria and other pathogens that can cause foodborne illnesses, ensuring that the food remains safe to eat for a longer period.

In contrast, keeping food at room temperature or in an open container on the counter allows bacteria to thrive, increasing the likelihood of spoilage and foodborne illnesses. Similarly, storing food in a paper bag does not provide the necessary protection from air and moisture, further compromising the quality and safety of the food. Adhering to proper food storage practices is essential for maintaining safety and quality.
