Bisphenol A (BPA) has become a known health hazard. This industrial chemical is used in a variety of materials to make polycarbonate. It's a type of plastic found in food and drink containers that makes the items shatter resistant, rigid, and see through. It is also used to make epoxy resins that line most of the food and beverage cans in the United States. Research has shown that BPA is present in 9 out of 10 cord blood samples and a 2011 study in the Journal of Agriculture and Food Chemistry found BPA was detected in 71 of the 78 canned food samples. BPA is a known hormone disruptor that is associated with increased breast cancer risk and autism. It has been shown in animals to cause insulin resistance and alter pancreatic cell function. To avoid BPA exposures make sure to purchase baby formula in non-metal containers. Also look for canned food that is labeled BPA-free. Avoid handling purchase receipts and have it emailed if it is an option) since they are known to be coated with BPA. If you do handle them then wash your hands right afterwards.
