How long does breast milk last after expression?

Understanding the Longevity of Expressed Breast Milk
Breast milk is a vital source of nutrition for infants, and understanding how long it lasts after expression is crucial for parents and caregivers. The storage duration of expressed breast milk varies significantly depending on the conditions under which it is stored.
Room Temperature Storage
When freshly expressed breast milk is left at room temperature, it can safely be stored for up to four hours. However, for optimal safety, it is recommended to use the milk within one to two hours if possible. After this period, the risk of bacterial growth increases, making it less safe for consumption.
Refrigeration Guidelines
For longer storage, refrigeration is a viable option. Expressed breast milk can be kept in the refrigerator for up to four days. It is essential to store the milk in the back of the fridge, where the temperature is most consistent, rather than in the door, which is subject to temperature fluctuations. If the milk is not used within this timeframe, freezing is advisable to preserve its quality.
Freezing Breast Milk
Freezing breast milk extends its shelf life significantly. In a standard freezer compartment of a refrigerator, expressed milk can last for up to two weeks. However, if stored in a standalone freezer at a temperature of -18°C (0°F) or lower, breast milk can remain viable for up to six months. Some sources even suggest that it can last up to a year, although the quality may diminish over time.
Thawing and Reusing Milk
Once frozen, breast milk should be thawed in the refrigerator or under warm running water. It is important to note that thawed milk should not be refrozen. If thawed milk is left at room temperature, it should be used within two hours.
Conclusion
In summary, the longevity of expressed breast milk is influenced by storage conditions. At room temperature, it lasts for a few hours; in the refrigerator, it can be kept for several days; and in the freezer, it can last for months. Understanding these guidelines helps ensure that infants receive safe and nutritious milk, supporting their health and development.
