A new paper, published today in the Proceedings of the National Academy of Sciences, indicates that triclosan impairs muscle function in both animals and humans. The study, conducted by researchers from the University of California, Davis, found that the chemical hinders human muscle contractions at the cellular level and inhibits normal muscle functioning in both fish and mice. “Triclosan is found in virtually everyone’s home and is pervasive in the environment,” said lead author Isaac Pessah. “These findings provide strong evidence that the chemical is of concern to both human and environmental health.”
The antibacterial substance, which was first developed in the 1960s to prevent bacterial infections in hospitals, has since been incorporated into everything from hand soaps to toothpastes to mouthwashes. Manufacturers see it as a marketing bonus, increasing consumer confidence that a particular product kills harmful bacteria. Even some household products—such as kitchen utensils, toys and bedding—include triclosan.
The FDA has declared that there is no evidence that using antibacterial soaps with triclosan confers any more health benefits than simply washing with conventional soap and water, and the agency is currently conducting a risk assessment for the chemical. ”Triclosan can be useful in some instances, however it has become a ubiquitous ‘value added’ marketing factor that actually could be more harmful than helpful,” said study co-author Bruce Hammock. “At the very least, our findings call for a dramatic reduction in its use.”
