Like any other equipment that comes into contact with breast milk, breast pumps require proper maintenance to ensure your baby’s safety. One common issue that many breastfeeding mothers face is mould growth in breast pump tubing.

This can be concerning as it affects the pump’s functionality and raises questions about the safety of expressed milk.

In this guide, we will discuss what mold in breast pump tubing looks like, how it can affect the pump and milk, and what steps you can take to prevent it.

Let’s get started!  

Mould can be easily identified in breast pump tubing through its appearance and smell. Here are some signs that indicate mold growth in your breast pump tubing:

• Black, brown or green spots are the most common mold colours that can appear inside breast pump tubes. If you notice any discolouration in your tubing, it is likely due to mould growth.
• Foul odour: Mould can give off a musty or sour smell. This is a clear indication of contamination and should not be ignored.
• Slimy texture: Mold can create a slimy film on the inner surface of the tubing, making it difficult for milk to flow smoothly through the pump.

Breast milk is a nutrient-rich and easily digestible food for babies. However, mould in the tubing can contaminate the expressed milk, affecting its quality and safety for consumption. Some potential risks of consuming mold-contaminated breast milk include:

• Gastrointestinal issues: Moldy breast milk may cause stomach upset, diarrhoea or vomiting in infants.
• Respiratory problems: Inhaling mold spores from contaminated breast pump tubing can lead to respiratory issues such as coughing and wheezing.
• Allergic reactions: Babies with allergies or compromised immune systems are at a higher risk of allergic reactions to mold-contaminated breast milk.

If you notice mold in your breast pump tubing, it is important to clean and disinfect the tubing thoroughly before using it again. Here are some steps you can follow to get rid of mold:

1. Remove the tubes from the pump and detach them from other parts.
2. Rinse the tubes with hot, soapy water to remove any milk residue.
3. Prepare a solution of equal parts water and white vinegar or bleach.
4. Submerge the tubes in the cleaning solution for 30 minutes.
5. After soaking, scrub the inside of the tubes with a bottle brush or toothbrush to remove any remaining mold or residue.
6. Rinse thoroughly with hot water and allow them to air dry before using them again.

Prevention is always better than cure, and this holds for preventing mold growth in breast pump tubing. Here are some measures you can take to avoid encountering mould:

• Properly clean and sanitize the tubing: After each use, disassemble the pump parts and wash them with hot, soapy water. Rinse thoroughly and allow them to air dry. Sanitize the parts daily by boiling for 5 minutes or using steam sterilization.
• Store your pump correctly: Always store your breast pump in a clean and dry place when unused. Avoid storing it in a damp or humid environment.
• Replace old tubing: Over time, tubing can become worn out and develop small tears or holes. It is important to replace the tubing every 3 months or as the manufacturer recommends.

Mold in breast pump tubing is a common issue that can have serious implications for both the pump and expressed milk. By properly identifying mold, taking necessary precautions, and regularly cleaning and sanitizing your equipment, you can ensure the safety of your baby’s food.

Always closely monitor your pumping equipment and take immediate action if you notice any signs of mold growth. Happy breastfeeding!
