Blinding With Science

Main DogYesterday’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 CanadaHealth 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.

Can We Bottle All That Phony Hysteria?

dog_snarling

As California prepares to turn loose tens of thousands of prisoners, extreme factions of the Legislature and activist groups are getting all lathered up about – get this – the supposed hazards of shatter-proof baby bottles (which incidentally have likely saved countless lives by preventing young children from choking to death).

As David Letterman would say: “I’m not making this up.”

Activist groups today are planning to adorn the State Capitol grounds with a 15-foot baby bottle as a PR stunt to push for Senate Bill 797 (Pavley), which would create the Toxin-Free Infants & Toddlers Act.

[Full Disclosure: The Blue Dog is working with opponents to kill this ridiculous bill]

In essence, SB 797 would ban a chemical known as Bisphenol-A (BPA) from baby bottles and other drinking containers used by children three and under. This would be a necessary and commendable goal if there were any serious science underlying the concern. Trouble is, even the state agency lauded by the environmentalists, doesn’t even see any reason for concern.

A scientific advisory board of The Office of Environmental Health Hazard Assessment (OEHHA) recently determined that BPA doesn’t even belong on the state’s Prop. 65 list of known carcinogens. Even wine and beer are on this list – but not BPA. Specifically, July 15 OEHHA’s Development and Reproductive Toxicant Identification Committee (DARTIC) unanimously voted NOT TO ADD BPA to the Proposition 65 list.

The Committee – consisting of experts from several California universities spanning a wide range of relevant scientific disciplines – serves as the “State’s Qualified Experts” for determining whether a chemical has been clearly shown, through scientifically valid testing according to generally accepted principles, to cause reproductive or developmental toxicity. If the state’s scientific experts do not believe products containing BPA deserve even a warning label, how is an outright ban warranted?

And the irony here gets quite tasty. Last month some of the proponents of SB 797 lobbied against the agency’s possible elimination, touting OEHHA as leaders in protecting public health through independent scientific research. They sent out press releases and wrote opinion pieces going to bat for the agency.

Now, when science-based policy doesn’t support activist driven policy, OEHHA’s science advisory board becomes the focus. Activists are now pouting that the “committee is made up of political appointees who do not necessarily have the research and science background best-suited to interpret cutting-edge science, as evidenced by this decision.”

So let’s get this straight: last month OEHHA worth saving from the budget ax, but this month the agency is being advised by political appointees who don’t have the expertise to make these decisions? Please, give us all a break.

The SB 797 special interests have also got to be annoyed with our northern neighbors and friends across the pond. After all, the U.S. activists love to fawn all over the EU and Canada when it comes to their chemical policies. So the following facts must also be hard for them to swallow:

  • Just last month, Health Canada released studies of BPA in infant formula and baby food containers and concluded “Based on the overall weight of evidence, as described in the Health Risk Assessment of BPA from food packaging applications, the results of this survey further confirms 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 consumer
  • Regulatory agencies in the EU, Japan, United Kingdom and Australia/New Zealand have looked at BPA as used in these applications and have not issued any restrictions.  Do we assume that those regulatory agencies are made up of unqualified political appointees too?
  • Finally, SB 797 flies in the face of the Green Chemistry initiative – the Governor and Legislature’s landmark measure to take chemical policy out of the hands of Legislators and into the hands of state scientists.

Why is a bill like this even circulating?

Pavely is a teacher and land use expert. Most, if not all of her colleagues have no serious scientific credentials. I don’t believe there is a toxicologist among them. Yeah, tree-tall baby bottles may make for snappy PR events and great TV news, but if you look inside this big bottle all you will see is special interest scare tactics and specious science.

Meanwhile, how about those freed inmates?
