A new peer-reviewed study has detected dangerous hormone-disrupting chemicals in breast milk samples from mothers in Seattle, including BPA, BPS, melamine, cyanuric acid, and triclosan. The research highlights a widespread systemic problem of chemical contamination, experts say.
Study Findings
About 92% of the 50 samples tested were contaminated with at least one antimicrobial or plasticizer. The same samples had previously been found to contain PFAS forever chemicals and flame retardants, which are also endocrine disruptors.
Ryan Babadi, lead author and senior scientist with Toxic Free Future, stated: "This pertains to the most vulnerable group when it comes to health effects – infants and children – who are undergoing rapid stages of development orchestrated by the endocrine system."
Chemical Presence
- BPA and BPS: Found in 74% and 78% of samples, respectively, linked to developmental and reproductive harms.
- Triclosan: Detected in 62% of samples, used as an antimicrobial in personal care products.
- Melamine: Found in 92% of samples, used as a plasticizer and resin.
While breastfeeding remains the healthiest choice, Babadi emphasized that the results underscore a systemic problem due to widespread chemical use and regulatory failures. The chemicals are found in everyday products, making it difficult for consumers to avoid them.
Regulatory Context
The study comes as the Trump EPA moves to undo limits on toxic chemicals. Babadi warned that rollbacks would worsen exposures and harm health. "We need stronger protections, not rollbacks," he added.
