Can you put breast milk in the fridge after its been at room temperature?

Understanding Breast Milk Storage: Room Temperature to Refrigerator
When it comes to the delicate process of storing breast milk, many parents find themselves asking whether it’s safe to refrigerate breast milk after it has been left at room temperature. The answer is nuanced, but generally, it is permissible under certain conditions.
Room Temperature Guidelines
Freshly expressed breast milk can safely remain at room temperature, which is defined as up to 77°F (25°C), for a maximum of four hours. This timeframe is crucial, especially in warmer climates or during hot weather, where the risk of bacterial growth increases significantly. If the milk has been left out for longer than this period, it is advisable to discard it to ensure the safety of the baby.
Refrigeration After Room Temperature
If you have breast milk that has been at room temperature and you plan to use it later, you can indeed place it in the refrigerator. The Centers for Disease Control and Prevention (CDC) recommends that if breast milk is not consumed within a few hours, it should be refrigerated to maintain its quality and safety. Once refrigerated, freshly pumped breast milk can last for up to four days at a temperature of 39°F (4°C).
Considerations for Previously Frozen Milk
For breast milk that has been thawed from a frozen state, the rules differ slightly. Thawed milk can also be stored in the refrigerator, but it should be used within 24 hours of thawing. Importantly, once thawed, it should not be refrozen.
Best Practices for Storage
To maximize the safety and quality of breast milk, it is essential to store it properly. Always place breast milk in the back of the refrigerator rather than in the door, as this area experiences more temperature fluctuations due to frequent opening and closing. Additionally, labeling the milk with the date it was expressed can help keep track of its freshness.
Conclusion
In summary, it is safe to refrigerate breast milk that has been at room temperature for up to four hours. However, if it has been left out longer than this, it should be discarded. By following these guidelines, parents can ensure that their babies receive safe and nutritious breast milk, even when managing the complexities of storage and feeding.
