The Food and Drug Administration ignored scientific evidence and used flawed methods when it determined that a chemical widely used in baby bottles and in the lining of cans is not harmful, a scientific advisory panel has found. In a highly critical report ... the panel of scientists from government and academia said the FDA did not take into consideration scores of studies that have linked bisphenol A (BPA) to prostate cancer, diabetes and other health problems in animals when it completed a draft risk assessment of the chemical last month. The panel said the FDA didn't use enough infant formula samples and didn't adequately account for variations among the samples. Taking those studies into consideration, the panel concluded, the FDA's margin of safety is inadequate". The panel is part of the Science Board, a committee of advisers to the FDA commissioner, and was set up to review the FDA's risk assessment of BPA. Many of the studies that the panel said the FDA ignored were reviewed by the National Toxicology Program, which concluded in September that it had "some concern" that BPA can affect brain and behavioral development in infants and small children. Officials at FDA, which regulates the chemical's use in plastic food containers, bottles, tableware and the plastic linings of food cans, accepted some of the criticism in the report. "FDA agrees that due to the uncertainties raised in some studies relating to the potential effects of low doses of bisphenol-A that additional research would be valuable," said spokeswoman Judy Leon. The agency has commissioned new research on BPA.
