The California State Assembly passed the 'Toxin-Free Infants and Toddlers Act' (AB 1319) on September 6, 2011, and Governor Jerry Brown (Democrat) signed the bill into law on October 5, 2011. The bill bans the use of Bisphenol-A (BPA) in childrens' products. The ban applies equally to domestic and imported products. It prohibits the manufacture, sale, or distribution in commerce in California of any baby bottles and sippy cups that contain BPA at a level above 0.1 parts per billion (ppb). The bill also requires manufacturers to use the least toxic alternative when replacing BPA in containers. The ban enters into effect as of July 1, 2013.
