Canada's proposed ban on a hormone-like chemical in baby bottles has spurred US retailers & legislators to try to phase out use of the ingredient, called bisphenol A, or BPA. Canada's announcement came just days after the National Toxicology Program,, found "some concern" that low levels of BPA cause changes in behavior & the brain, prostate gland, mammary gland & the age at which girls enter puberty. Toys 'R' Us announced recently it will phase out bottles & other "baby feeding products" containing BPA by end-2008. Wal-Mart also said that it will stop selling baby bottles made with BPA by early 2009. Nalgene, which makes plastic water bottles popular with hikers & Playtex, which makes a variety of baby products, also say they'll stop using BPA, an ingredient in polycarbonate plastic.
