How long can frozen breast milk stay out once thawed?

Understanding Thawed Breast Milk Storage
When it comes to the safe handling of thawed breast milk, parents and caregivers must be aware of specific guidelines to ensure the health and safety of their infants. The process of thawing breast milk is crucial, as improper handling can lead to waste and potential health risks.
Thawed Breast Milk at Room Temperature
Once breast milk has been thawed, it is important to note that it should not be left out at room temperature for extended periods. According to health guidelines, thawed breast milk can safely remain at room temperature for up to two hours. After this time, any leftover milk should be discarded to prevent the risk of bacterial growth.
Thawed Breast Milk in the Refrigerator
If thawed breast milk is placed in the refrigerator, it has a longer shelf life. Specifically, it can be stored in the refrigerator for up to 24 hours after it has been completely thawed. This timeframe begins once the milk is fully thawed, not from when it was first placed in the refrigerator . This allows parents some flexibility in managing feeding schedules without compromising the milk’s safety.
Key Considerations
It’s essential to remember that once breast milk has been thawed, it should never be refrozen. This is a critical point to ensure the milk’s quality and safety. Additionally, caregivers should avoid using microwaves or boiling water to thaw breast milk, as these methods can damage its nutritional properties and create hot spots that could scald a baby.
In summary, thawed breast milk can be safely kept at room temperature for two hours and in the refrigerator for 24 hours. Adhering to these guidelines helps ensure that infants receive the best nutrition without compromising their health.
