How should leftover food be properly stored?

Storing leftover food in airtight containers that are labeled with the date and contents is essential for maintaining food safety and quality. Airtight containers help to prevent the growth of bacteria and limit exposure to air, which can lead to spoilage. By labeling the containers with the date and contents, you can easily track how long the food has been stored and ensure that you consume it within a safe time frame. This practice minimizes the risk of foodborne illness and helps maintain the food's flavor and texture.

In contrast, using any available container may lead to improper sealing, which does not protect the food adequately. Leaving food uncovered in the refrigerator exposes it to potential contaminants and can cause drying out or the absorption of odors from other foods. Similarly, placing food on a shelf without a lid does not provide protection from bacteria, air, or cross-contamination, which can compromise food safety.
