How quickly does breast milk go bad?

Understanding the Shelf Life of Breast Milk
Breast milk is a remarkable substance, tailored by nature to provide optimal nutrition for infants. However, like all perishable items, it has a limited shelf life, and understanding how quickly it can go bad is crucial for ensuring the health and safety of your baby.
Storage Guidelines
The longevity of breast milk largely depends on how it is stored. When left at room temperature, expressed breast milk typically remains safe for up to three hours. If you’re unable to use it within this timeframe, refrigeration is the next best option. In the refrigerator, breast milk can last for up to four days, although experts recommend using it within three days for optimal freshness and safety.
For longer storage, freezing is an effective method. Breast milk can be stored in a freezer at temperatures of -18 °C (0 °F) for six to twelve months, although the quality may begin to decline after six months. It’s important to note that using a standard freezer compartment in a refrigerator may limit storage time to just two weeks.
Signs of Spoilage
Determining whether breast milk has spoiled is essential for preventing any health risks to your infant. A key indicator of spoilage is a sour smell; if the milk smells off, it should not be used. Additionally, while it’s normal for breast milk to change color or separate, these changes do not necessarily indicate spoilage.
Conclusion
In summary, breast milk can last for three hours at room temperature, up to four days in the refrigerator, and six to twelve months in the freezer. By adhering to these guidelines and being vigilant about signs of spoilage, parents can ensure that their babies receive the safest and most nutritious milk possible.
