August 8 2007. Laboratory tests of canned infant formula conducted by the Food and Drug Administration (FDA) and a certified commercial laboratory reveal that a plastics chemical called bisphenol A (BPA) leaches from metal can linings into formula. According to a new EWG analyses, the amount of BPA ingested by some bottle-fed infants exceeds the doses that caused serious adverse effects in animal studies.

Not trying to start a bottle vs. breast debate, just wanting to warn people who do happen to formula feed for whatever reason.
