How to spot germs in your baby’s equipment

It’s important to understand that your baby’s equipment can become a place for germs to grow if it isn’t cleaned and dried properly. When we talk about ‘germs’ on baby equipment, it doesn’t just mean visible dirt. Everyday items like bottles, teats, dummies and toys are constantly in contact with milk, saliva and moisture, creating the perfect environment for germs to thrive. In a study by Dr P. Mason and published in the Journal of Community Medicine & Public Health, 56.3% of baby bottles are contaminated by E.coli and other harmful bacteria.

In this guide, we’ll explain how to spot different germs and how Milton products help combat them.

Types of germs

Bacteria

Bacteria like E.coli, Cronobacter and Salmonella can thrive on baby equipment, particularly in feeding bottles, teats, and formula preparation machines. Proper sterilisation, using boiling water for formula, and thorough cleaning are essential to stop bacteria from growing.

Yeast and mould

Yeast and mould are created when the baby equipment becomes moist, such as trapped water and warm conditions that bath toys are exposed to. It’s a lot safer to replace the products entirely than cleaning them to be extra safe, as yeast and mould can cause risks like skin and respiratory issues and infections.

Biofilm

Biofilm on baby equipment can be very dangerous and is often invisible. It shows up as a slimy layer of bacteria and fungi, forming inside tiny cracks in bottles, teats and dummies. Make sure to inspect bottles and teats regularly to keep germs and biofilm at bay.

It’s hard to tell whether these germs are present because they’re usually invisible, which is why knowing what to look out for can help you keep your baby’s equipment clean and safe to use.

Spotting the germs

Because germs are too small to see, knowing the signs will help keep your baby safe. Checking your little one’s equipment regularly can help you catch early problems, such as residue, unpleasant smells or slimy textures, before they develop into a health risk for your baby.  

Visual signs to look out for:

• Cloudy or milky film on bottles or teats that don’t rinse away easily
• White, grey, green or black spots which may be a sign of mould or yeast
• Discolouration or yellowing of plastic over time
• Sticky or slimy patches which are especially inside bottle necks and tubing
• Residue around seams and joins where milk and moisture can get trapped
• Cracks, or worn areas are a key spot for germs to hide and grow inside

Smells to look out for:

After washing and drying items, give them a quick smell as your nose is useful when it comes to spotting germs on baby equipment. Clean equipment should smell like nothing at all. If you notice a musty or damp odour, or an old milk smell (especially inside bottles, teats or pump parts) then this often signals that milk residue or moisture has been left behind, creating the perfect condition for bacteria or yeast to grow.

Textures to look out for:

Another simple way to check baby equipment is by how it feels. After washing and drying it’s important to pay attention to any unusual textures:

• Slimy or slippery surfaces can be a sign of biofilm
• Chalky or powdery residue often means dried milk or formula build up has happened
• Sticky patches from leftover sugars like milk or juice can encourage yeast to grow

You don’t need special tools to check baby equipment for germs. A simple look, smell and feel can tell you a lot.

Common problem areas

Some parts of baby equipment are more likely to trap germs because they collect moisture, milk, food residue, or are difficult to reach when cleaning. Here are some high-risk areas to be aware of:

• Bottle teats  
• Breast pump parts
• Bottle necks and lids
• Straws, sippy cup valves and small feeding parts
• Soft toys and teethers
• Toy seams, cracks, and textured surfaces
• Changing mats and highchairs
• Bath toys and cups

Focusing on these hotspots helps prevent germs from multiplying before they can reach your baby.
