How long can breast milk be stored in the refrigerator?

The shelf life of breast milk in the refrigerator mainly depends on the storage method and refrigerator temperature. In the refrigerated compartment (0–4°C), breast milk can typically be stored for up to 8 days. However, it is generally recommended not to exceed 72 hours to minimize the risk of bacterial growth. If breast milk is stored in a freezer compartment within the refrigerator, its shelf life can be extended to 15 days. In a standard freezer compartment where the door is frequently opened and closed, breast milk can be stored for approximately 90–120 days. In a deep freezer, where the temperature remains consistently below 0°C and the door is rarely opened, breast milk can be safely stored for more than six months. It should be noted that although breast milk can be stored for extended periods, its nutritional components gradually degrade over time, leading to a reduction in nutritional value. Additionally, improper storage may lead to bacterial contamination, potentially affecting the infant's health. Therefore, when storing breast milk, it is advisable to use dedicated breast milk storage bags or bottles, ensuring that all containers are clean and properly sterilized.
