Chemical in Soda Cans, Baby Bottles May Harm Kids (Update3)
By Tom Randall
Sept. 3 (Bloomberg) -- Exposure to bisphenol A, a chemical used to make plastic for baby bottles and to line soda cans, may harm fetuses and children and needs further study before it is deemed safe, a U.S. government report found.
Tests in animals showed harmful effects from the chemical, known as BPA, the National Toxicology Program said today in a report that rated concern about the chemical's risks for children at the middle of a five-point scale. Parents may want to limit family exposure to the substance, said the study's authors, though they didn't recommend changing U.S. safety standards.
The study, the final version of a report issued in draft form in April, underscores differences within the government about the chemical's safety. The staff of the Food and Drug Administration said in a draft report last month that the agency ``has concluded that an adequate margin of safety exists'' for bisphenol A when used in products coming into contact with food.
``The possibility that BPA may affect human development cannot be dismissed,'' said John Bucher, associate director of the toxicology group, in a statement today. ``We see developmental changes occurring in some animal studies at BPA exposure levels similar to those experienced by humans.''
The National Toxicology Program, part of the Health and Human Services Department, was created in 1978 to provide scientific assessments of the health effects of chemical agents in the environment, according to the program's Web site.
The FDA's staff assessment also recommended more detailed testing, specifically in adult, pregnant and newborn monkeys, to look for effects on nervous system development and behavior. A subcommittee of the FDA's Science Board plans to review the agency's staff report at a Sept. 16 meeting in Rockville, Maryland.
Industry Response
``There is no direct evidence that exposure to bisphenol A adversely affects human reproduction or development,'' said the American Chemistry Council, which represents the chemical industry, in an e-mailed statement today. Evidence from animal studies was ``limited and inconclusive'' and ``additional research will be needed to determine if these concerns are relevant,'' the group said.
In April, Canada became the first country to label bisphenol A as ``toxic'' and is considering a ban on its use in baby bottles. U.S. lawmakers have considered similar proposals to prohibit use of the chemical.
``We should err on the side of caution and keep this chemical out of children's products,'' said Senator Charles Schumer, a New York Democrat, in an e-mailed statement today. ``Clearly more research is needed.''
Coca-Cola, PepsiCo
Bisphenol A is used to stiffen plastic used to make baby bottles and to seal canned food. Coca-Cola Co. and PepsiCo Inc. use it in cans to protect the drink from direct contact with the aluminum and to prevent spoilage, said Tracey Halliday, a spokeswoman for the American Beverage Association, a Washington- based trade group.
Coca-Cola and Pepsi, which referred questions about bisphenol A to the beverage association, don't use the chemical in soft drink and water bottles, Halliday said.
Several companies that produce plastic bottles, such as Energizer Holding Inc.'s Playtex Infant Care unit and Thermo Fisher Inc., the maker of Nalgene sports bottles, have stopped using the chemical in their new products because of the concerns.
Average infant exposures are about 2,000 times less than the FDA's safety level, and exposures among adults are 27,000 times lower, that agency's draft report said.
