Bisphenol A (BPA) is found in polycarbonate plastic—usually marked with recycling symbol No. 7 and “PC”. Not all No. 7 plastic contains BPA, so look for products specifically labeled as "BPA-free." Most canned foods and metal jar lids have BPA-based linings, unless the company has indicated otherwise, and are thought to be a major source of current BPA exposure.
Bisphenol S (BPS) is found in some thermal paper cash register receipts, and appears to have similar health risks as BPA.
* Under our weak federal laws, it's impossible for us to know all the uses of BPA and BPS in consumer products. As a result, this is not an exhaustive list of all products containing BPA or BPS.
