Baby bottle chemical draws mixed messages from U.S.

By Will Dunham

WASHINGTON (Reuters) - The Food and Drug Administration this week reopens the debate over a chemical used in many plastic products -- including baby bottles -- amid mixed messages on its safety from the U.S. government.

An FDA panel of outside experts on Tuesday was set to review the agency's draft report issued last month saying that bisphenol A, or BPA, is safe. Critics argue the FDA has ignored strong evidence in animal studies that BPA is harmful.

Government toxicologists at the U.S. National Institutes of Health on September 3 reiterated their view that BPA presents "some concern" for harmful effects on development of the prostate and brain and for behavioral changes in fetuses, infants and children.

BPA is used to make polycarbonate plastic, a clear shatter-resistant material in products ranging from baby and water bottles to sports safety equipment and medical devices.

It also is used to make durable epoxy resins used as the coating in most food and beverage cans and in dental fillings.

People can consume BPA when it leaches out of plastic into liquid such as baby formula, water or food inside a container.

Environmental and consumer safety groups say studies show the chemical can interfere with how the body absorbs the hormone estrogen, which is key to the development of young bodies.

The NIH's National Toxicology Program, or NTP, became the first U.S. government agency to embrace health concerns regarding BPA. It followed up this draft report with a final report this month reiterating the concerns.
