Babies drink a large amount of breast milk and/or formula. Breast milk (human milk) that has been pumped and formula are often stored in plastic, warmed and served in plastic bottles. As a result, babies may unintentionally ingest small plastic particles, known as microplastics. To date, it is not clear whether these microplastics are harmful to babies’ health. In this study, we collect breast milk and formula samples to measure microplastic content. Additionally, we investigate whether alternative methods of storing, heating and serving breast milk/formula can reduce microplastic exposure.
What does participation involve?
Breast milk: We ask participants to collect a small amount of breast milk into a glass jar on two occasions. We will pick up the samples.
Questionnaire: We also ask participants to complete an online questionnaire on how they prepare breast milk or formula for their babies and their views on plastic and its alternatives. This will take approximately 20-30 minutes.
Who can participate?
- You are over 18 years old;
- You are currently breastfeeding;
- You speak Dutch or English.
