The specific dye in question is called o-anisidine. It’s not regulated in the U.S. (outside of workplace exposure guidelines), and since textile manufacturers are not required to put that sort of info on their goods, it’s very difficult to know whether or not o-anisidine was used to color a product.

🚨 A new @ucsfhealth.bsky.social study finds pregnant women exposed to a toxic clothing dye called o-anisidine are more likely to develop gestational diabetes, especially when carrying a male fetus.
