BPA on sales receipts ?
Next time at the check out counter at your local grocery store, consider washing your hands after handling sales receipts (a universally recommended practice even for those who have not handled receipts)
If you are unsure, check whether paper is thermally treated by rubbing it with a coin. Thermal paper discolors with the friction; conventional paper does not.
The plastic component bisphenol A (BPA) has been in the headlines nonstop as scientists, health experts and consumers press for a federal ban on food packaging made with this synthetic estrogen, shown to leach readily into infant formula, beverages and canned food. But most Americans are probably unaware that they are regularly exposed to the same endocrine-disrupting chemical in cash register receipts.
Two-fifths of the paper receipts tested by a major laboratory commissioned by Environmental Working Group were on heat-activated paper that was between 0.8 to nearly 3 percent pure BPA by weight. Wipe tests conducted with a damp laboratory paper easily picked up a portion of the receipts’ BPA coating, indicating that the chemical would likely stick to the skin of anyone who handled them. The receipts came from major retailers, grocery stores, convenience stores, gas stations, fast-food restaurants, post offices and automatic teller machines (ATMs).
Major retailers using BPA-containing receipts in at least some outlets included McDonald’s, CVS, KFC, Whole Foods, Walmart, Safeway and the U.S. Postal Service. Receipts from some major chains, including Target, Starbucks and Bank of America ATMs, issued receipts that were BPA-free or contained only trace amounts.
