Expressed breast milk should be stored in a clean container for up to 5 days in the refrigerator, as this ensures the milk remains safe and maintains its nutritional quality. Using a clean container is essential to prevent contamination and bacterial growth, which can compromise the milk's safety for the infant.

Storage guidelines recommend that breast milk kept in a refrigerator at a temperature of 39°F (4°C) or below can last for this timeframe due to the preservation of its cellular structure and nutrients. This duration provides a practical balance between convenience for caregivers and safety for the baby.

Other methods mentioned, such as using a paper bag, plastic wrap, or an unsealed container, may not offer the necessary protection from contamination or the proper environment for maintaining the milk’s integrity. For instance, a paper bag or unsealed containers could allow for exposure to air and bacteria, while plastic wrap may not provide a secure seal to keep the milk safe. Therefore, employing a clean, robust container is the best practice for storing expressed breast milk in the refrigerator.
