The Washington Post reports that Playtex Products of Westport, Connecticut is the target of a federal lawsuit filed by an Arkansas woman claiming that the manufacturer's baby bottles are made with an industrial chemical harmful to infants. The chemical, bisphenol A, was the subject of a report by the National Toxicology Program last month concluding that animal studies linking it to behavioral changes, early puberty, and pre-cancerous changes in the breast and prostate provided evidence of "some concern" about harm to humans. According to the Washington Post, a Playtex spokesperson insisted that the chemical had been deemed safe by U.S. regulators.
