Canadian Study Finds 'BPA-free' Bottles Still Leach Chemical

OTTAWA -- Health Canada scientists have found bisphenol A leaching into liquid in plastic baby bottles marketed to parents as being free of the toxic chemical.
The study says "traces" of the toxin were found in "BPA-free" bottles while internal correspondence between a department official and the lead scientist went further, characterizing the amounts in two brands as "high readings."
Manufacturers of non-polycarbonate plastic baby bottles, however, were quick to challenge the "shocking" results, saying there must be a problem with the way the agency conducted the research.
Government scientists conducted the tests on non-polycarbonate bottles last year after Health Canada announced an imminent ban on polycarbonate plastic baby bottles.
By then, the market had already been flooded with "BPA-free" alternatives made of substitute plastics without any bisphenol A, which were pitched as an option for parents concerned about health risks.
Bisphenol A, a hormone disrupter that can cause reproductive damage and may lead to prostate and breast cancer in adulthood, is used as a building block in polycarbonate plastic, but not in the substitutes, such as polypropylene.
The test results surprised Health Canada scientists, according to records released to Canwest News Service under the Access to Information Act.
"This bottle is labelled polypropylene which should contain no BPA," the lead scientist wrote to a colleague, recommending another analysis be done to "verify the claim."
The brand mentioned in the correspondence is blacked out on the grounds that the information could result in financial loss or prejudice the competitive advantage of a company.
