"Worried about bisphenol A in food? Before you shop..."
Believe it or not -- considering all of the negative publicity the chemical bisphenol A has received, resulting in efforts to ban its use in baby bottles and other items for small children -- scientists didn't get around to publishing a peer-reviewed study measuring levels of the chemical in U.S. food until this week. The work was published online Tuesday in the journal Environmental Science & Technology. A research team led by Arnold Schecter of the University of Texas School of Public Health measured 105 foods purchased from grocery stores in Dallas in March 2010. They detected "quantifiable levels" of bisphenol A, which is often used to line food cans and to harden plastics, in 63 of them. The BPA levels detected by the researchers were almost 1,000 times lower than the tolerable daily intake levels set by the U.S. Environmental Protection Agency and the European Food Safety Authority, the scientists reported. But many researchers aren't convinced that those guidelines are appropriate. The paper reported that studies have identified adverse affects at lower doses.
