THE WHAT? A new test designed to detect human BPA exposure by measuring BPA metabolites has revealed the method used by the US Food and Drug Administration to be wildly inaccurate, according to a report published by Reuters.
THE DETAILS The old and new methods were used to test 39 human urine samples and average exposure levels were found to be up to 44 percent lower when using the old method.
“This study raises serious concerns about whether we’ve been careful enough about the safety of this chemical,” Patricia Hunt, Senior Study Author of Washington State University told Reuters.
THE WHY? BPA exposure has been linked to problems with growth, metabolism, behaviour and fertility. The higher the levels, the higher the risk so measuring exposure accurately is crucial to determining risk and assessing product safety.
