You’ve heard about the chemical BPA that’s been linked to health problems. It’s found in food and water containers, but not just there. BPA is found in a lot of receipts too. The thermal paper ones contain the most. You can protect yourself by declining receipts or have them emailed to you instead. Stash your receipts in a plastic bag. And if you handle receipts often, wear gloves. And lastly, wash your hands with soap and water after handling them. Don’t use hand sanitizer, that makes BPA leach into your skin more easily.
