[Update @ 1534 -- I forwarded this story to a friend who is very involved in the chemical end of environmental concern and she just emailed me back to say that:
I called Whole Foods HQ in Austin. Most of their stores are bpa-free (re: the receipts) and the rest will be converted within the next 2 months.
My guess is that now that the big name stores have been named on national news, they'll all convert.
I have to wonder if that includes Walmart.]
Strictly speaking, this is not a Walmart story but, because of Walmart’s ubiquitous place in retailing, I have to think that Walmart produces more of this particular health hazard than a large number of the others guilty of ignorance.
The solution could be devastatingly expensive.
From the Environmental Working Group:
The plastic component bisphenol A has been in the headlines nonstop as scientists, health experts and consumers press for a federal ban on food packaging made with this synthetic estrogen, shown to leach readily into infant formula, beverages and canned food. But most Americans are probably unaware that they are regularly exposed to the same endocrine-disrupting chemical in cash register receipts.
Two-fifths of the paper receipts tested by a major laboratory commissioned by Environmental Working Group were on heat-activated paper that was between 0.8 to nearly 3 percent pure BPA by weight. Wipe tests conducted with a damp laboratory paper easily picked up a portion of the receipts’ BPA coating, indicating that the chemical would likely stick to the skin of anyone who handled them. The receipts came from major retailers, grocery stores, convenience stores, gas stations, fast-food restaurants, post offices and automatic teller machines.
Major retailers using BPA-containing receipts in at least some outlets included McDonald’s, CVS, KFC, Whole Foods, Walmart, Safeway and the U.S. Postal Service. Receipts from some major chains, including Target, Starbucks and Bank of America ATMs, [emphasis mine, JH] issued receipts that were BPA-free or contained only trace amounts.
