Human exposure to bisphenol A (BPA) has been associated with adverse health outcomes, including reproductive function in adults1 and neurodevelopment in children exposed perinatally.2 Exposure to BPA is primarily through dietary ingestion, including consumption of canned foods.3 A less-studied source of exposure is thermal receipt paper,4 handled daily by many people at supermarkets, ATM machines, gas stations, and other settings. We hypothesized that handling of thermal receipts significantly increases BPA exposure, but use of gloves during handling minimizes exposure.
