If you're specifically worried about BPA, perhaps a larger exposure is handling cash register receipts. Don't take em if you don't need em, and wash your hands before you eat anything if you do need to handle them.
That might explain why I've watched almost all newcomer cashiers in our local supermarket gain weight quickly after starting their job. Of course, the stress might also be to blame.
whoa, I never thought about chemical contact from receipts. Would love to see things go the way of Square where my itemized receipt is just emailed to me.
