"There is no excuse for this avoidable and unconscionable threat to continue," Blumenthal said. In October, Blumenthal and his counterparts in New Jersey and Delaware wrote to the companies asking them to stop using the controversial chemical, widespread in plastic, after studies linked BPA to a range of health problems in infants. Six Firms Stop Using BPA In Baby Bottles Officials said that the six major baby bottle makers in the United States have agreed to stop using the toxic chemical Bisphenol-A, which is suspected of harming human development. "I am calling for a complete ban against BPA in baby products to stop this needless and negligent public health threat." The chemical might interfere with the brain development of fetuses and newborns, according to what Toxicologists at the National Institutes of Health found last year. "All six major baby bottle companies -- Avent, Disney First Years, Gerber, Dr. Brown, Playtex and Evenflow -- have agreed to voluntarily ban BPA from bottles in a major public health victory," Connecticut Attorney General Rudy Blumenthal said in a statement.

Over the past decade, more than 130 studies have linked even low levels of BPA to serious health problems, breast cancer, obesity and the felice onset of puberty, among other disorders.
