How long does breast milk keep once defrosted?

Understanding the Shelf Life of Defrosted Breast Milk
Breast milk is a precious resource for feeding infants, and understanding how to store and handle it safely is crucial for maintaining its nutritional quality. Once breast milk has been frozen and subsequently thawed, its shelf life changes significantly, and caregivers must adhere to specific guidelines to ensure the milk remains safe for consumption.
Thawing and Immediate Use
When breast milk is thawed, it is essential to use it promptly. According to health guidelines, once previously frozen breast milk is defrosted, it should ideally be used within 24 hours if stored in the refrigerator. This timeframe is critical because the quality and safety of the milk can diminish over time due to bacterial growth and nutrient degradation.
Room Temperature Considerations
If thawed breast milk is brought to room temperature, it should be consumed within 1 to 2 hours. This shorter window is designed to minimize the risk of bacterial contamination, which can occur more rapidly at warmer temperatures. If a baby does not finish a bottle of thawed milk, any leftover milk should also be used within this 1 to 2-hour period to ensure safety.
Storage After Thawing
It’s important to note that once breast milk has been thawed, it should not be refrozen. The process of freezing and thawing can alter the milk’s composition, and refreezing can further compromise its safety and nutritional value. Therefore, careful planning is essential when thawing breast milk to avoid waste.
Conclusion
In summary, once breast milk is thawed, it should be used within 24 hours if kept in the refrigerator, or within 1 to 2 hours if left at room temperature. Adhering to these guidelines helps ensure that the milk remains safe and nutritious for your baby, allowing caregivers to provide the best possible feeding experience.
