KQED today brings us this report about a move in the California Assembly to ban Bisphenol-A, a.k.a. BPA, a widely used chemical in plastic packaging. It's been known to be potentially hazardous since the 1930s, and lots of scientists think it's probably the reason why everyone gets cancer these days, but a large enough study in humans has yet to be done. The proposed ban would only affect plastics in baby bottles and baby foods, and Connecticut and Minnesota have already passed similar bans. Di Fi is proposing a nationwide ban in the Senate that would affect all food products. In the radio piece below, Sarah Varney speaks with a California Pacific Medical Center researcher who's been injecting the stuff into human cells and who consequently probably only shops at the farmer's market.
