The June 2 Health article “ Ban on an antimicrobial ingredient raises questions downplayed the risks of exposure to triclosan and other endocrine disrupters.

A growing body of research shows that triclosan alters levels of thyroid and reproductive hormones in disturbing ways. Triclosan is shaping up to be the new bisphenol A (BPA).

Despite the evidence, triclosan remains widespread in products marketed to people, including pregnant women and infants. Conscientious consumers must read tiny labels to determine which household products contain this endocrine-disrupting chemical. People have the right to know what they are buying, and they should be aware that washing with antibacterial soap containing triclosan may do more harm than good.
