Bisphenol A (BPA)

Why am I being warned about potential exposure to bisphenol A?

  • Bisphenol A is on the Proposition 65 list because it can harm the female reproductive system, including effects on ovaries and eggs.
  • Proposition 65 requires businesses to determine if they must provide a warning about exposures to listed chemicals.

What is bisphenol A?

  • BPA is a widely used chemical.  Sources of exposure to BPA include:
    • Some linings that prevent rust, corrosion, and contamination in metal food and drink cans, jar lids, and bottle caps.
    • Polycarbonate (PC) plastic items such as some water bottles, water cooler bottles, dishes and utensils, cookware, food storage containers, and electric kettles.
      • Items made of this hard plastic often have the recycle code “7”, “3”, or “PC”.
    • Some polyvinyl chloride plastics (sometimes called PVC or vinyl), such as some plastic food wrap and some vinyl gloves.
    • Some thermal paper, which has a glossy surface and is often used for receipts such as from cash registers, gas pumps, and ATMs.

How does exposure to bisphenol A occur?

How can I reduce my exposure to bisphenol A?

  • Store food and liquids in glass or stainless steel rather than plastic containers.
  • Avoid using polycarbonate plastic containers and tableware for hot food or drinks.
  • Avoid microwaving polycarbonate plastic containers.
  • Avoid washing polycarbonate plastic containers in the dishwasher.
  • If you bottle-feed your infant, use glass bottles.
  • Eat more fresh food and less canned food, if possible.
  • Because BPA can get on your hands after touching some receipts, or coming in contact with BPA-containing dust, wash your hands and your child’s hands frequently with soap and water, especially before preparing food and eating. 
  • Because BPA can be present in dust, reduce dust in your home by dusting and cleaning your floors regularly with a wet mop or a vacuum with a high efficiency particulate air (HEPA) filter, if possible. 
  • If your dentist recommends sealants or fillings, ask about BPA-free options.
