Yesterday’s post on bisphenol-A and Senate Bill 797 (Pavley) drew a healthy reader comment as well as a few offline requests to see links to the research mentioned in the post. And why not? We should be making policy on facts and science — not emotion. Here is some of the science underlying the worldwide regulatory view that there is no compelling evidence at this time that BPA poses a health and should be banned. But read and draw your own conclusions:
State of California [OEHHA]: “Following the staff presentation, comments from the public and committee discussion, the DARTIC determined that, based upon current scientific information, bisphenol A has not been clearly shown to cause reproductive toxicity; and therefore the Committee declined to add it to the Proposition 65 chemical list.”
[As an aside, how do the scientists at OEHAA feel about being dismissed at political appointees? They looked at the research trumpeted by Pavley and bill proponents and rejected it. So how come their public employee union — the California Association of Professional Scientists — isn’t standing up to defend them and their work? ]
Health Canada: Health Significance of the Survey Results – The provisional tolerable daily intake (TDI) of 25 µg/kg body weight/day has been pre-established by Health Canada as a conservatively safe level for BPA presence in food. Based on the average BPA level in canned drinks (0.57 µg/L*), if an adult (60 kg body weight) consumes one canned drink (355 mL) per day, the dietary intake of BPA would be equivalent to 0.2 µg/day which represents 0.0135% of the provisional TDI. Based on the highest BPA level in canned drinks (4.5 µg/L*), an adult (60 kg body weight) would have to consume approximately 940 canned drinks in one day to approach the provisional TDI set by Health Canada.
The results of this survey clearly indicate that exposure to BPA through the consumption of canned drink products would be extremely low. The low levels of BPA found in canned drink products available for sale in Canada confirm Health Canada’s previous assessment conclusion that the current dietary exposure to BPA through food packaging uses is not expected to pose a health risk to the general population.
European Union: European safety watchdogs reaffirm belief in safety of BPA
Food Standards Australia New Zealand (FSANZ): FSANZ has assessed the risk to infants from exposure to BPA and concurred with the conclusions reached by the US FDA and the EFSA that the levels of exposure are very low and do not pose a significant health risk.
