Bisphenol A (BPA)

Why am I being warned about potential exposure to BPA?
  • BPA is on the Proposition 65 list because it may harm the developing baby, and it may harm the female reproductive system, including the ovaries and eggs.
  • Proposition 65 requires businesses to determine if they must provide a warning about exposure to listed chemicals.
What is BPA?

BPA is a chemical used in a variety of plastics, resins, and coatings.  Sources of exposure to BPA include:

  • Some linings in metal food and drink cans, jar lids, and bottle caps.
  • Polycarbonate plastic items: some water bottles, jugs for water dispensers, dishes, utensils, cookware, food storage containers, and electric kettles.  Items made of this hard plastic often have recycle code 3 or 7.
    • BPA may be present in baby bottles and sippy cups made before July 2012.
  • Some polyvinyl chloride plastics (sometimes called PVC or vinyl), such as some plastic food wrap and vinyl gloves.
  • Some thermal paper that has a glossy surface and is often used for receipts from cash registers, gas pumps, and automated teller machines (ATMs).

How does exposure to bisphenol A occur?
How can I reduce my exposure to BPA?
  • Store food and drinks in glass or stainless steel containers, rather than plastic ones.
  • If you use polycarbonate plastic containers or tableware:
    • Avoid using them for hot food and drinks.
    • Avoid placing them in the microwave oven or the dishwasher.
  • If you bottle-feed your infant, use glass bottles.
  • Choose food and drinks that do not have Proposition 65 warnings for BPA, if possible.
  • Choose more fresh food and less canned food, if possible.
  • Minimize your exposure to thermal paper and dust.
    • Wash your hands and your child’s hands frequently with soap and water, especially before preparing food and before eating. 
    • Clean surfaces and floors regularly.  Use a damp cloth, wet mop, or vacuum cleaner with a high-efficiency particulate air (HEPA) filter, if possible.
  • If your dentist recommends sealants or fillings, ask about BPA-free options.
