In February, a group of Food and Drug Administration scientists published a study finding that low-level exposure to the common plastic additive bisphenol A (BPA) is safe. The media, the chemical industry, and FDA officials touted this as evidence that long-standing concerns about the health effects of BPA were unfounded. (“BPA Is A-Okay, Says FDA,” read one Forbes headline.) But, behind the scenes, a dozen leading academic scientists who had been working with the FDA on a related project were fuming over the study’s release—partly because they believed the agency had bungled the experiment.
On a conference call the previous summer, officials from the FDA and the National Institutes of Health (NIH) had informed these researchers that the lab where the study was housed was contaminated. As a result, all of the animals—including the supposedly unexposed control group—had been exposed to BPA. The FDA made the case that this didn’t affect the outcome, but their academic counterparts believed it cast serious doubt on the study’s findings. “It’s basic science,” says Gail S. Prins, a professor of physiology at the University of Illinois at Chicago, who was on the call. “If your controls are contaminated, you’ve got a failed experiment and the data should be discarded. I’m baffled that any journal would even publish this.”
Yet the FDA study glossed over this detail, which was buried near the end of the paper. Prins and her colleagues also complain that the paper omitted key information—including the fact that some of them had found dramatic effects in the same group of animals. “The way the FDA presented its findings is so disingenuous,” says one scientist, who works closely with the agency. “It borders on scientific misconduct.”
