Bottle manufacturer Nalgene will stop using plastic containing bisphenol A in response to concerns from the National Toxicology Program and the Canadian health department that the chemical probably shouldn’t be sucked on by kids. Nalgene says it still believes its clear, hard plastic bottles “are safe for their intended use” but says it’s responding to customers who “indicated they preferred BPA-free alternatives.” Wal-Mart also announced it would pull all baby bottles made with BPA from its shelves by early next year.
