Numerous prior posts noted that nearly everyone in the U.S. has low levels of BPA in their body, and have reviewed the animal and laboratory studies which indicate that BPA exposure may have adverse health effects on humans. It has also been noted that recent evidence indicates that the major vector for BPA exposure is cash-register receipts (thermal paper).
Responding to concern about BPA, to date 11 states have banned BPA-containing baby products, and many other states are considering a ban on BPA in food containers, especially those used by infants. In October 2011 California passed legislation banning (effective July 1, 2013) the manufacture, sale, or distribution of any bottle or cup that contains bisphenol A, at a detectable level above 0.1 parts per billion (ppb), if the bottle or cup is designed or intended to be filled with any liquid, food, or beverage intended primarily for consumption by children 3 years of age or younger. [See http://www.leginfo.ca.gov/pub/11-12/bill/asm/ab_1301-1350/ab_1319_bill_20111004_chaptered.html.] In June 2009, Connecticut became the first state to ban the chemical in reusable food and beverage containers and in containers for infant formula and baby food.
Now, Campbell's has announced that it will begin phasing out the use of BPA in its soup can liners. [See http://www.forbes.com/sites/amywestervelt/2012/03/05/under-pressure-from-parents-advocacy-groups-campbells-goes-bpa-free/.] BPA has been found in a variety of Campbell's products. Also, as noted in a prior post, by the end of March 2012 FDA will announce its conclusions on BPA.
What is ironic is that steps have not been announced to remove BPA from thermal paper used in cash-register receipts, a significant source of exposure to the general populace.
