UC Davis Professor of toxicology, Isaac Pessa was involved in the study. He says Triclosan is used to treat gingivitis, but it's also in cosmetics and clothing so manufacturers can say those products are anti-bacterial, "We're essentially putting millions of pounds of the material every year into close proximity of homes - in fact, in the home. So, I think we need to reassess the risks and the benefits for this compound."
Pessa says Triclosan doesn't stay in the body long, but our exposure to it is near constant. He says the long-term biological effects are unknown, but people with heart disease, and older people may be at risk for effects from exposure.
The study appears at the Proceedings of the National Academy of Sciences of the United States of America website and was conducted with researchers from the University of Colorado Denver-Anschutz Medical Campus in Aurora.
