Refrigerated breast milk is a valuable resource for new mothers, providing essential nutrients and antibodies for their babies. However, it’s important to know how long this milk can safely sit out at room temperature before it needs to be discarded. The answer depends on several factors, including the temperature of the room and how the milk was handled.
The general rule of thumb is that refrigerated breast milk can sit out at room temperature for up to four hours. This allows for convenient feeding during short outings or if the baby needs to be fed in the middle of the night. However, it’s crucial to carefully monitor the temperature and ensure that it stays at a safe level for consumption.
If the room temperature exceeds 25 degrees Celsius or 77 degrees Fahrenheit, the milk should not be left out for more than two hours. Higher temperatures can promote the growth of harmful bacteria, which can lead to foodborne illnesses. Therefore, it’s essential to store refrigerated breast milk properly and be mindful of the room temperature.
It’s important to note that once the baby has started drinking from a bottle of refrigerated breast milk, it should be discarded within two hours. Bacteria from the baby’s mouth can contaminate the milk, making it unsafe to consume after that time. To minimize waste, it’s advisable to store breast milk in smaller portions and only thaw what the baby will consume in one feeding.
