How should leftovers be stored to maintain safety?

Storing leftovers in an airtight container is crucial for maintaining safety. An airtight container helps to prevent exposure to air, which can lead to oxidation and spoilage of food. This type of storage also protects leftovers from contaminants and reduces the risk of bacterial growth. Properly sealing containers keeps leftovers fresher for longer, minimizes odors from spreading in the fridge, and helps avoid cross-contamination with other food items.

In contrast, leaving leftovers out on the counter can lead to rapid bacterial growth, as the warm environment allows pathogens to thrive. Using a paper bag does not provide adequate protection against moisture and air, which can accelerate spoilage. Storing food in the pantry is unsuitable for perishable items, as most leftovers must be kept cold to inhibit bacterial growth effectively. Therefore, using an airtight container is the best practice to ensure food safety when storing leftovers.
