'BPA-free' bottles leach chemical: study
JONATHAN HAYWARD / THE CANADIAN PRESS ARCHIVES Enlarge Image
Manufacturers are questioning test results that found bisphenol A in baby bottles that are being marketed as free of the chemical, which Health Canada has banned for use in bottles intended for infants.
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.
The records show Health Canada tested about nine different brands of baby bottles using non-polycarbonate plastic for possible leaching of BPA, chosen because they're made with a type of plastic that does not use the chemical as a building block.
In a recently published summary of the test results, researchers suggest the "traces of BPA found to migrate from these bottles could be artifacts of the manufacturing process."
And since these "BPA-free" bottles leached less than polycarbonate plastic bottles under conditions designed to simulate repeated normal use, the government researchers concluded these bottles made of polysulfone, polystyrene or polypropylene (non-PC) are a "reasonable alternative" to the banned polycarbonate (PC) bottles.
University of Missouri's Frederick vom Saal, a leading researcher into bisphenol A and other endocrine disrupters, said even if trace amounts can be explained away as a result of environmental contamination, companies need to revisit their manufacturing processes.

I am 100% in support of breast feeding but, my daughter had a liver transplant at 4 months-old due to a birth defect called Biliary Atresia, which causes liver failure. During the surgery, her lymphatic system had to be dissected, rendering her unable to properly digest fats for several months and she had to go on intravenous nutrition while she recovered. Afterward, I tried to go back to nursing. I tried every day for hours with skin-to-skin contact, among other suggestions from lactation specialists, but she refused. I was heartbroken but continued to pump and feed her via bottle until my milk dried up when she was around a year old. I used plastic bottles that were supposed to be BPA-Free.
Why are the specific bottles/makers not sited in this article?
Also, in the future, there are bottles made from corn-based plastics, as well as glass bottles available on the market today. For anyone who bottle feeds, I suggest seeking out those products.
These manufacturers make such products:

It is nice for you to say to breastfeed, but what about those who cannot. My daughter was unable/unwilling to latch on properly and began suffering from jaundice, and we had to move to formula. And what about those who adopt? I support breastfeeding, but we also need to provide safe alternatives when breastfeeding is not an option.

Breast feed! Breast feed your child anywhere, anytime! Let's make this a USUAL sight, and a cause for people to say "Awwww, isn't that sweet?"
