Kary exposed health risks posed by antibacterial chemical triclosan in Colgate Total toothpaste, in part by examining pages of Colgate-Palmolive's Food and Drug Administration application that were kept private after the toothpaste's 1997 approval. These previously undisclosed pages, summaries of scientific studies Colgate submitted as part of its new-drug application, contained indications of a potential health danger in one of America's top-selling toothpastes, according to scientists who reviewed them for Bloomberg News. Kary's article raises important questions, including whether the FDA did appropriate due diligence in approving Total 17 years ago, and whether its approval should stand in light of new research. By combining tough and fair investigative reporting, clear science writing and an examination of America's regulatory system, Kary's piece gave readers a valuable new tool for decision-making on an important health and wellness front.
