Consensus science continues to demonstrate the safety of BPA as a food packaging compound.  Past and present studies confirm that BPA is rapidly absorbed, detoxified and eliminated from the body.  People are exposed to BPA primarily through the diet and according to a new study published on line in Toxicological Sciences (June 2011), the blood concentrations are below detectable levels and lower than those that cause effects in laboratory rodents.  Moreover, as stated by global health authorities, “the majority of effects observed in animal studies are probably not relevant to humans because they involved much higher BPA exposure.”  

BPA:  New Scientific Study Supports Safety – Diminishes Concerns

A new study, published online in June 2011 in Toxicological Sciences provides definitive answers to questions about BPA.  The study also adds to the growing body of scientific evidence that supports the safe use of BPA.

First of all, the study’s lead author Dr. Justin Teeguarden set out to better understand the internal exposure of adult humans to BPA.  In this study which was conducted in collaboration between three outstanding research institutions: The Pacific Northwest National Laboratory in Richland, Washington; the Division of Laboratory Sciences of the National Center for Environmental Health of the HHS Centers for Disease Control and Prevention in Atlanta, Georgia; and the Division of Biochemical Toxicology of the FDA National Center for Toxicological Research in Jefferson, Arkansas, Dr. Teeguarden and his colleagues collected and analyzed samples over a 24-hour period from a number of volunteers who had eaten breakfast, lunch and dinner – all meals from standard store food considered rich in BPA.

As the research was finalized, Justin concluded “we can now say for the adult human population exposed to even very high dietary levels, blood concentrations of the bioactive form of BPA throughout the day are below our ability to detect them, and orders of magnitude lower than those causing effects in rodents exposed to BPA.”  To make this research and findings more significant, Dr. Teeguarden’s analyses were duplicated in two separate labs with experience in measuring trace levels of contaminants.  This is what scientists call a study that is properly designed, replicated and includes straight-forward findings that are important to the scientific community and thus important to regulators, health professionals and the public.

Here’s what you need to know:

BPA has been safely used around the world for over 40 years as an effective food packaging compound.  Given the exposure of BPA from food in the diet, there is currently no reason for consumers to change their eating habits or purchase behavior.
