The internet is abuzz with consumers pissed off about bottle maker Sigg's admission that until recently its liners contained bisphenol A (BPA). The sad thing is, it dissembled about that fact for a looong time, carefully crafting language to imply the bottles were BPA-free and thereby capitalize on the scads of people getting rid of their polycarbonate vessels. Read Z Recommends' excellent reporting about it (as well as how to tell if your liner is old or new) here. Notably, some consumers who have bought Sigg bottles as recently as this month have still gotten the old liners—a testament to how long the supply-chain process can be.
The blog's follow-up post on the subject is also troubling: the supposedly better new Sigg liners have been found to chip away from the necks of the bottles, which are aluminum (cue alarm bells going off).
I have to agree with Real Green Girl: While it's good to be assured that known bad things are missing from a given product, the important issue is what's in the thing. (And frankly, if it's chipping off the inside of my bottle, I don't care what it is—I don't want it!)
