Understanding Breast Milk Storage After Defrosting
Breastfeeding mothers often juggle the demands of feeding their infants with the practicalities of storing breast milk. One common question that arises is how long defrosted breast milk can be safely kept in the refrigerator.
Storage Duration After Defrosting
Once breast milk has been thawed, it is crucial to handle it properly to ensure the safety and health of the baby. According to guidelines from reputable health organizations, defrosted breast milk can be stored in the refrigerator for up to 24 hours. This timeframe is critical; after this period, the milk should not be used and should be discarded to prevent any risk of bacterial growth.
Temperature Considerations
When storing defrosted breast milk, it is essential to keep it at a consistent refrigerator temperature, ideally below 4°C (39°F). If the milk has been left out at room temperature, it should be consumed within two hours to ensure it remains safe for the baby .
Best Practices for Thawing and Storing
To maintain the quality of breast milk, it is recommended to thaw it gradually in the refrigerator rather than using quick methods like microwaving, which can create hot spots and degrade the milk’s nutrients. Once thawed, mothers should label the milk with the date and time it was defrosted to keep track of its freshness.
In summary, after defrosting, breast milk can be safely stored in the fridge for 24 hours. Adhering to these guidelines not only ensures the milk remains safe for consumption but also supports the health and well-being of the infant.
