How long can freshly expressed breast milk be stored?

Patient's question:

The child has just been born, and their appetite is still small. They cannot eat breast milk, so the breast milk needs to be expressed. How long can breast milk stored immediately after being extracted be kept?

Doctor's answer:

Hello, according to the situation you described: freshly expressed breast milk should be stored in a constant-temperature refrigerator for no more than 24 hours. If it is consumed within one or two hours, it can be temporarily stored without refrigeration. In hot weather, even refrigerated, it is not advisable to store for too long. Prolonged exposure can easily allow bacteria to grow in the breast milk, which is not good for the baby's growth. Refrigerator storage: 0—4℃ refrigeration can preserve for 8 days.
