How long does milk stay in breast milk?

Understanding Breast Milk Storage: Duration and Guidelines
Breast milk is a vital source of nutrition for infants, and understanding how long it can be safely stored is crucial for breastfeeding parents. The duration that breast milk remains viable depends on several factors, including the storage method and temperature.
Room Temperature Storage
When breast milk is left at room temperature, it can typically remain safe for up to four hours. However, in warmer climates or during hot weather, it’s advisable to use it within two hours to ensure its safety and quality. This guideline helps prevent bacterial growth, which can occur more rapidly in warmer conditions.
Refrigeration Guidelines
For longer storage, breast milk can be placed in the refrigerator. Under optimal conditions, it can last up to 5 to 8 days in a refrigerator set at or below 4 °C (39 °F). It’s essential to store the milk in clean, airtight containers and to ensure that it is placed in the back of the fridge, where the temperature is most consistent, rather than in the door, which can be subject to temperature fluctuations.
Freezing Breast Milk
Freezing breast milk extends its shelf life significantly. When stored in a standard freezer at -18 °C (0 °F), breast milk can remain safe for up to six months. Some sources even suggest that it can be stored for up to twelve months if kept in a deep freezer. However, it’s important to note that milk stored in the small freezer compartments of older refrigerators should ideally be used within two weeks.
Thawing and Reusing Frozen Milk
Once frozen breast milk is thawed, it should be used within 24 hours if kept in the refrigerator. If thawed milk is left at room temperature, it should be consumed within one to two hours. Importantly, previously frozen milk should never be refrozen, as this can compromise its quality and safety.
Conclusion
In summary, breast milk can be safely stored for varying durations depending on the method used. At room temperature, it lasts for a few hours; in the refrigerator, it can last up to a week; and in the freezer, it can remain viable for several months. By following these guidelines, parents can ensure that their infants receive the best possible nutrition while minimizing waste.
