Proposition 65 requires California businesses to post a list of chemicals that cause cancer, birth defects, or reproductive harm. Bisphenol A (BPA) is one of over 900 chemicals listed on California's list of chemicals known to the state to cause cancer or reproductive toxicity (1,2).
The Toxicant Identification Committee (DARTIC) reviewed more than 300 human and laboratory studies on the female reproductive effects of BPA. The committee concluded that BPA can harm the female reproductive system.
There is widespread exposure to BPA. When CDC scientists measured BPA in the urine of 2,517 people, almost all of the individuals tested had BPA in their urine (3).
BPA is found in plastic products, as well as food and drink packaging. Epoxy resins containing BPA are found in the metal coating in food cans and bottle tops. BPA can leach into food from the canned food coating.
Women in their childbearing years should take steps to limit exposure to BPA. Choose BPA-free cans, plastic bottles and beverage containers. Choose fresh, whole food and limit consumption of canned and packaged food.
