You’ve seen the headlines: “Chemical in Plastic Bottles Causing Alarm, Plastic Baby Bottles Pulled from Shelves.”

But what is this chemical and how exactly does it affect you? In short, Bisphenol A (BPA) is used in many polycarbonate plastics (found in tableware and storage containers) and epoxy resins (lacquers that coat many food cans and bottle tops). The problem: BPA can migrate from containers to food, and studies in animals suggest that, at least for fetuses, infants, and children, exposure to BPA may be harmful. During the week of April 14, the U.S. Food and Drug Administration launched a task force to explore BPA but isn’t currently suggesting an all-out ban. (The American Chemistry Council defends the safety of products that contain BPA.) Here, the facts on plastics and canned goods — it’s up to you to decide whether to expose yourself to BPA.
