WASHINGTON (AP) -- The federal government announced Tuesday that baby bottles and sippy cups can no longer contain the chemical bisphenol-A, or BPA.
It is illegal for companies to use substances not covered by FDA rules.
"Consumers can be confident that these products do not contain BPA," FDA spokesman Allen Curtis said in a statement, adding that the agency's action was based on the bottle industry's phase out of the chemical. "The agency continues to support the safety of BPA for use in products that hold food."
The chemical industry's request may help curb years of negative publicity from consumer groups and head off tougher laws that would ban BPA from other types of packaging because of health worries.
Legislation introduced by some members of Congress would ban BPA nationwide in all canned food, water bottles and food containers. Chemical makers maintain that the plastic-hardening chemical is safe for all food and drink uses.
BPA is found in hundreds of plastic items from water bottles to CDs to dental sealants. Some researchers say ingesting the chemical can interfere with development of the reproductive and nervous systems in babies and young children. They point to dozens of studies showing such an effect from BPA in rodents and other animals.
But the FDA has repeatedly stated that those findings cannot be applied to humans. The federal government is currently spending $30 million on its own studies assessing the chemical's health effects on humans.
About 90 percent of Americans have traces of BPA in their urine, mainly because the chemical leaches out of food and beverage packaging. The vast majority of canned goods in the U.S. are sealed with resin that contains BPA to prevent contamination and spoiling. Canned food manufacturers have used the chemicals since the 1950s. The practice is approved by the FDA.
