How long can breast milk be stored in the refrigerator?

The storage duration of breast milk in a refrigerator varies depending on the refrigeration conditions. Generally, breast milk can be stored for 24 to 72 hours in a refrigerator compartment maintained at 0-4°C. However, the optimal time for usage is within 24 hours after refrigeration to ensure freshness and nutritional value. If longer storage is required, breast milk can be stored in the freezer compartment. In the freezer compartment, the storage duration of breast milk can be extended to two to three months or even longer. However, if the freezer door is frequently opened and the temperature fluctuates, the storage duration will be shortened accordingly. Additionally, in a deep freezer where the temperature remains consistently below 0°C and the door is not frequently opened, breast milk can be stored for more than six months. Although breast milk can be stored through refrigeration or freezing, it is recommended to feed the baby fresh breast milk whenever possible. This is because the nutritional components of breast milk may gradually diminish over time, and bacteria may develop, potentially affecting the baby's health.
