The congressman wrote a letter to FDA commissioner Andrew von Eschenbach April 4, asking him to provide more information about the decision by April 22.
"Federal regulatory panels do not want to acknowledge the reality that who pays for science makes a difference," charged Frederick Vom Saal, a reproductive biologist and endocrinologist at the University of Missouri who first studied BPA as a sex hormone.
Vom Saal hopes that today's evaluation will prompt the FDA to look more closely at the science that shows BPA could be harmful. "What we're beginning to see is a convergence of opinions on this from various agencies," he said.
New mothers like Sarah Janssen believe it's best to limit exposure to BPA. Janssen, a science fellow at the Natural Resources Defense Council, actively avoided eating canned food and drinking canned sodas while pregnant to limit her exposure to the chemical often found in the products' linings. She also makes sure to use baby bottles, dishes and bowls that don't contain the chemical for her 8-month-old daughter.
"Although all those exposures by themselves are small, they add up in a day's time," Janssen said. "My evaluation of the research has really made me want to limit her exposure, and my exposure when I was pregnant, to this chemical."
"It affects babies a lot more than it would adults," said Ron Vigdor, CEO of Born Free, a company that manufactures BPA-free baby bottles. "I think that parents frankly are scared. Some of the parents are horrified at finding out that baby products could be leaching products and hurting their children."
Chemical evaluations like the one released this week are used to guide state and federal regulators in setting standards for exposure to the chemical, as well as for cleanup procedures.
The chemical evaluation of BPA is a draft open for public comment. The report will be reviewed by other scientists at a meeting in North Carolina this June.
