BPA, a plastic hardener and synthetic estrogen linked by researchers to a long list of serious health problems, is used to coat thermal paper used by major retailers, grocery stores, convenience stores, gas stations, fast-food restaurants, post offices and automatic teller machines (ATMs). The chemical reacts with dye to form black print on receipts handled by millions of Americans every day.WASHINGTON, DC – Laboratory tests commissioned by Environmental Working Group (EWG) have found high levels of the endocrine-disrupting chemical bisphenol A (BPA) on 40 percent of receipts sampled from major U.S. businesses and services, including outlets of McDonald's, CVS, KFC, Whole Foods, WalMart, Safeway and the U.S. Postal Service. Receipts from Target, Starbucks, Bank of America ATMs and other important enterprises were BPA-free or contained only trace amounts.The good news is that other well-known outlets, including Target, Starbucks, Bank of America ATMs and the U.S. Senate cafeteria, appear to be using receipt paper without BPA. In another positive development, Appleton Papers Inc. of Appleton, Wisc., the nation’s largest thermal paper maker, removed the chemical from its products in 2006.
