What is the best practice for storing leftovers?

Storing leftovers in a covered container in the refrigerator is the best practice for several reasons. Firstly, this method helps to prevent contamination from other food items and reduces the risk of bacteria growth. Food left uncovered is susceptible to absorbing odors from other foods and can become dry or lose quality. Refrigeration is essential as it slows down the growth of bacteria, extending the shelf life of the food.

Moreover, using a covered container helps maintain the moisture and prevents the food from drying out, ensuring that it stays safe to eat and retains its flavor and texture when reheated. This practice is part of proper food safety guidelines designed to minimize the risk of foodborne illness and maintain food quality. Other options like leaving food uncovered at room temperature, storing it outside, or placing it in a freezer without wrapping do not provide the necessary protection and safety that covered storage in the refrigerator offers.
