What to do with expired breast milk
Breast milk is produced by a woman’s breast shortly after birth as food for the baby. Breast milk is a primary newborn food source and contains fat, protein, carbohydrates, minerals, and vitamins. It provides the baby with all the necessary nutrients in the right proportions and protects it from allergies, illness, and obesity. This is the reason why babies have a robust immune system.
It also protects the baby from diabetes, cancer, and infections. Breastfed infants have a lower risk of asthma, obesity, type 1 diabetes, and sudden infant death syndrome. They also have fewer gastrointestinal infections because milk passes the mother’s antibodies to the baby.
Your baby can survive on breast milk for the first six months alone. It contains all the nutrients a bay needs. In this article, you will learn more about breast milk’s expiration date, storage, and uses of breast milk.
Understanding Expiration Dates for Breast Milk
Explanation of expiration dates for breast milk
Freshly pumped milk can be stored at room temperature (77°F or colder) for up to 4 hours, in the refrigerator for up to 4 days, or in the freezer for about six months at best. In the freezer, it can stay up to 12 months. The date on the container or bag should be when the oldest breastmilk was expressed.
How to check if breast milk is expired
If you smell fishy, sour, unpleasant, and not fragrant, then breast milk is spoiled or expired. That means you should have a taste yourself. Here are some other ways to check if breast milk is expired or spoiled:
- Look for changes in appearance: While color and appearance are not reliable safety indicators, spoiled breast milk may appear clumpy or have a sour smell.
- Check for signs of spoilage: Spoiled breast milk may have an off smell, taste, or appearance. It may also contain bacteria or other harmful pathogens that can cause illness.
- Shake the milk: Gently shake it to see if it mixes smoothly. Spoiled breast milk may separate or have chunks.
Why is expired breast milk not recommended for babies?
Expired breast milk causes stomach cramps and food poisoning. Babies using spoiled, expired, or lumpy breast milk cause stomach cramps, bloating, upset stomach, and fussiness. Spoiled breast milk will be contaminated, causing infant infection with bacteria, diarrhea, and vomiting (Familyorganics.com). It can affect a baby’s health. Initial symptoms may include baby crying and squirming.
What to do if you have expired breast milk
You can put it to good use by making milk baths. Breast milk baths can help with dry skin, cradle caps, rashes, eczema, the itch of bug bites, or skin conditioning. It also reduces swelling and inflammation due to its healing properties. Expired breast milk can also be frozen into cubes to treat minor cuts, scrapes, and bruises. Label it so you do not mix it with milk for consumption (Mayoclinic.org).
How to Safely Store Breast Milk
Best practices for storing breast milk
Here are some other best procedures for storing breast milk:
- Use proper storage containers: Use clean, capped food-grade plastic or glass containers or breast milk storage bags to store breast milk. Avoid containers of potentially harmful materials, such as soft plastic or BPA-containing materials.
- Label and date the milk: Always label it before storing it in the refrigerator or freezer. This will help you track when the milk was expressed and when it should be used.
- Store in the back of the fridge or freezer: Store breast milk in the back of the refrigerator or freezer, where temperatures are the most consistent. Avoid storing milk in the door of the fridge or freezer, where temperatures can fluctuate more.
