How long is frozen breast milk good for once reheated?

Understanding the Safety of Reheated Breast Milk
When it comes to the safety and longevity of breast milk, particularly after it has been reheated, there are specific guidelines that parents should follow to ensure their baby’s health.
Duration of Use After Heating
Once breast milk has been heated, it is crucial to use it within a two-hour window. The Centers for Disease Control and Prevention (CDC) emphasizes that warmed breast milk should not be left out for longer than this period to minimize the risk of bacterial growth. If the milk is not consumed within two hours, it should be discarded to ensure safety.
Storage After Thawing
For breast milk that has been previously frozen and then thawed, the rules are slightly different. After thawing, this milk can be safely stored in the refrigerator for up to 24 hours. However, it’s important to note that this 24-hour countdown begins only after the milk has completely thawed, not from the moment it is removed from the freezer .
Reheating and Refreezing Guidelines
While it may be tempting to refreeze thawed breast milk, it is generally advised against doing so. Refreezing can compromise the quality and safety of the milk, and it is best to use thawed milk within the specified time frames to avoid any health risks.
In summary, once breast milk is reheated, it should be used within two hours. If it has been thawed from frozen, it can be kept in the refrigerator for up to 24 hours but should not be refrozen. Following these guidelines helps ensure that your baby receives safe and nutritious milk.
