Moldy Milk: Tips for Preventing Breastmilk Contamination While Pumping

We all know that breastfeeding is often regarded as the best way to nourish your baby, providing essential nutrients and fostering a strong bond. It’s also beneficial for moms, helping them return to their pre-pregnancy weight, reduce the risk of certain cancers, and support heart health. But let’s be real—breastfeeding isn’t always a walk in the park. Many moms face challenges that make direct breastfeeding difficult, whether it’s returning to work, juggling other kids, or having a baby in the NICU.

That’s where breast pumps come into play! For centuries, these handy devices have allowed moms to express milk for later use. With various options available—manual, battery-operated, or electric—finding the right pump can make a difference. Generally speaking, hospital-grade double-electric pumps are your best bet for efficient milk expression.

However, it’s crucial to consider the type of pump you’re using, especially regarding contamination risks. Pumps can be classified as either “open” or “closed” systems. In a closed system, there’s a protective barrier between the parts that come into contact with your milk and those that don’t, preventing any backflow and contamination. This design makes hospital-grade pumps safe for multiple users. On the other hand, open system pumps lack this barrier, allowing moisture and milk to potentially infiltrate the tubing and pump motor—creating a cozy environment for mold.

How to Keep Mold at Bay

So, how do you keep mold at bay in your breast pump and your milk? First, regular cleaning is key. After each use, make sure you thoroughly clean and dry all parts that touch your milk, including flanges, bottles, and valves. Wash them with warm, soapy water, and then rinse thoroughly with hot water. It’s best to let them air dry on a clean paper towel or drying rack. Avoid cloth towels, which can harbor germs.

You don’t need to clean the tubing unless it directly contacts milk. If you do wash it, hang it to air dry before reattaching it. If you see condensation in the tubing after pumping, simply attach it to the pump and run it briefly to dry it out.

What to Do If You Find Mold

If you happen to find mold in your breast milk or pump parts, don’t panic! It’s essential to consult your pediatrician, especially if your baby is sick or premature. An algorithm has been developed to help manage potentially contaminated breast milk. The first step is to discard any milk with visible foreign material, like mold. Then, consider when you last cleaned your pump to assess potential contamination of previously expressed milk. If you’re in need of alternatives, you might want to explore using donor milk or formula, depending on your situation.

Support and Resources

While breastfeeding can be quite a challenge, remember that you’re not alone. There are resources available to help, such as lactation consultants and supportive communities.
