Bisphenol A Science Uncertainty

The Raleigh News and Observer ran a story today about the findings from a recent Food and Drug Administration report that suggests bisphenol A (BPA) is less harmful than previously expected. Meanwhile WRAL, a Raleigh news station, ran a story on the dangers of bisphenol A.

BPA is used in hardened plastics and in a wide range of consumer goods, including the lining of metal cans, eyeglass lenses and compact discs. Many scientists believe it can act like the hormone estrogen, and animal studies have linked it with breast, prostate and reproductive system problems and some cancers.

To make things confusing, the FDA did not recommend any change in habits but they did suggest tips on how people could avoid exposure. For instance people should avoid plastic containers imprinted with the recycling number '7,' as many of those contain BPA. People should also avoid warming food in such containers, as heat helps to release the chemical.

Several states are considering restricting BPA use, some manufacturers have begun promoting BPA-free baby bottles, and some stores are phasing out baby products containing the chemical. The European Union has said BPA-containing products are safe, but Canada's government has proposed banning the sale of baby bottles with BPA as a precaution.
