How do you know when frozen breastmilk has gone bad?

Understanding Frozen Breast Milk Spoilage
For breastfeeding mothers, ensuring the safety and quality of expressed breast milk is paramount. While freezing breast milk is a common practice to preserve its nutrients and make feeding more convenient, it’s crucial to know how to identify when frozen breast milk has gone bad. Spoiled breast milk can pose health risks to infants, so being vigilant is essential.
Signs of Spoilage
1. Unpleasant Odor: One of the most telling signs that frozen breast milk has spoiled is its smell. Fresh breast milk typically has a mild, sweet scent. However, when thawed, it may develop a metallic or sour odor. This change in smell can indicate spoilage, although some mothers report that thawed milk can have a slightly unpleasant scent due to high lipase levels, which is a natural enzyme in breast milk that breaks down fats. If the milk smells distinctly sour or rancid, it is best to discard it.
2. Changes in Appearance: When breast milk is frozen, it often separates into two components: a creamy fat layer and a liquid. This separation is normal and does not indicate spoilage. However, if you notice any unusual discoloration or the presence of clumps that do not mix back into the liquid upon gentle shaking, this could be a sign that the milk has gone bad. Fresh breast milk should appear creamy and uniform when properly thawed.
3. Taste Test: While not always practical, tasting a small amount of thawed breast milk can also help determine its freshness. If the milk tastes sour or off, it is advisable not to feed it to your baby.
Storage Guidelines
To minimize the risk of spoilage, adhering to proper storage guidelines is essential. The Centers for Disease Control and Prevention (CDC) recommends that frozen breast milk can be stored in a standard freezer for up to 12 months, although using it within six months is ideal for maintaining quality. Always label containers with the date of expression to keep track of how long the milk has been stored.
Conclusion
In summary, knowing how to identify spoiled frozen breast milk involves being attentive to changes in smell, appearance, and taste. By following proper storage practices and regularly checking for these signs, mothers can ensure that their babies receive safe and nutritious milk. If there is any doubt about the quality of the milk, it is always safer to err on the side of caution and discard it.
