A new study published in Environment International by researchers
in Sweden confirms previous reports that bisphenol A (BPA) in human
blood is below the levels that can be detected. In addition to
confirming results from earlier studies that found BPA in human blood at
non-detectable levels, the new Swedish study went a step further. The
study also demonstrated the level of effort required to avoid
contamination and suggested that early studies showing BPA in blood
samples were almost certainly overstated due to sample contamination.
"It's been well documented that BPA is very quickly metabolized and
removed from the body, which is why previous results showing high levels
of BPA in human blood samples were difficult to understand," said Dr.
John M. Rost, NAMPA Chairman. "The Swedish study, along with other
recently published studies (Teagarden, et al.), confirms that BPA
is not in blood and explains how it could have been found in early
studies. Specifically, the Swedish study has validated the fact that
sample contamination is extremely difficult to remove and any study that
does not take this into consideration needs to be scrutinized for its
ability to produce valid results."
Dr. Rost noted that these results provide further scientific evidence to
support the positions taken by regulatory bodies around the globe, which
repeatedly have concluded that current uses of BPA in food conact
applications are safe. Those regulatory bodies include:
The North American Metal Packaging Alliance, Inc., and its members
support sound science and trust the scientific review process that has
protected our food supply for decades. For further information, visit www.metal-pack.org.
