Senator Edward J. Markey (D-MA) and Representatives Lois Capps (D-CA) and Grace Meng (D-NY) have introduced the Ban Poisonous Additives (BPA) Act to bar the use of bisphenol A (BPA) in food and beverage containers nationwide in both reusable containers and food and beverage packaging. The bill has the support of 20 national labor unions and nearly three dozen health and environmental groups. More than a dozen states now have BPA restrictions in place and the FDA has discontinued its approval of BPA use in baby bottles. Big question: How to ensure that replacement chemicals and materials will be safe?
