i dunno, i find that most of the things that have been recalled are china made. the whole led issue in toys a couple of years ago, the baby bottles, and so on. they just use a lot of bad chemicals in some of their stuff. of course not all of their things are bad, just i'd be a bit cautious.
some ways to see if they've been treated are if they have a gloss of some kind to them. wood is NOT meant to be glossy. also, scrape your nail along it, if a wax comes off of it, it's got a chemical coating on it (i have a basket like that, it's only used for storing my make-up though). also, ask someone to make sure it's real wood (not that fake stuff). i'm sure there are more ways to tell, but i cant think of them atm.
