"In January, the Food and Drug Administration, which previously called BPA safe, announced it has "some concerns" about the chemical's potential effects on brain development of fetuses, infants and children. It did not say BPA is unsafe.
The Environmental Working Group recommends these tips for reducing BPA exposure from receipts:
Minimize receipt collection by declining receipts at gas pumps, ATMs and other machines when possible.
Store receipts separately in an envelope in a wallet or purse.
Never give a child a receipt to hold or play with.
After handling a receipt, wash hands before preparing and eating food (a universally recommended practice even for those who have not handled receipts).
Do not use alcohol-based hand cleaners after handling receipts. A recent study showed that these products can increase the skin's BPA absorption.
Take advantage of store services that email or archive paperless purchase records.
Do not recycle receipts and other thermal paper. BPA residues from receipts will contaminate recycled paper.
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.
