Recently, the U.S. Food and Drug Administration (FDA) announced a ban on the use of bisphenol A, or BPA, in baby bottles and children’s cups. BPA is an estrogen-mimicking chemical that has been used in hard plastics, the linings of cans, food packaging, and dental fillings, even receipts–for which the Environmental Protection Agency is now investigating alternatives–for years. We’ve reported about the dangers of BPA on Civil Eats here, here, and here. This move essentially made official a practice that many manufacturers of baby bottles and cups already follow in response to growing pressure from consumers.
Questions of safety remain when it comes to the use of any plastic products that come in contact with our foods. The FDA ban is raising concern and creating headlines about what manufacturers will substitute in place of the BPA. A 2011 study published in Environmental Health Perspectives found that all plastics contain estrogenic activity (EA) and in some cases, those labeled “BPA free” leached more chemicals with EA than did BPA-containing products. The study’s authors write, “Almost all commercially available plastic products we sampled—independent of the type of resin, product, or retail source—leached chemicals having reliably detectable EA, including those advertised as BPA free.”
