What to know: BPA is used to line most metal food and drink cans. A 2007 study by the Environmental Working Group found that over half of the 97 canned goods tested contained BPA. Chicken soup, ravioli, and infant formula included the highest levels of BPA, with one in three cans of infant formula exceeding the government’s recommended safe level of chemical exposure by 200 times.
What to look for: Powdered baby formula or cans free of BPA. Eden Foods is thought to be the only known brand of BPA-free canned goods that are manufactured in the United States, and the only canned product it produces is beans. The beans are packed in lead-free tin-covered steel cans coated with a baked-on oleoresinous C enamel lining (a mixture of a natural oil and resin extracted from plants such as pine and balsam fir) that does not contain BPA.
