Dangerous Hormone-Disrupting Chemicals Found In US Breast Milk Samples [1]

"Study of mothers in Seattle underscores ‘widespread, systemic problem’ of chemical contamination, experts say"

"Breast milk samples from mothers in Seattle contain alarming levels of dangerous hormone-disrupting chemicals, including BPA, BPS, melamine, cyanuric acid, and triclosan, new peer-reviewed research has found.

The chemicals present a serious risk to infants because they likely interfere with hormones that are critical to newborns’ proper development, and have been found to be harmful at very low levels of exposure. About 92% of 50 samples were contaminated with at least one of the anti-microbials or plasticizers for which researchers checked.

The same milk samples had previously been found to contain potentially dangerous levels of PFAS “forever chemicals” and flame retardants, which are also endocrine disruptors.

The cocktail of endocrine-disrupting chemicals is “concerning for a number of reasons”, said Ryan Babadi, a lead author of the peer-reviewed study, and senior scientist with the Toxic Free Future nonprofit."
