Well, therein lies the problem. I, too, have been given an impression that they are "safe." Perhaps they are "safer" but apparently they aren't actually safe.
2 things:
-California had a bill (that wasn't passed) trying to stop some polycarbonates particularly baby bottles and things that babies use? Not sure, I think you can find the details in the article link I posted.
-I'm skeptical that any plastic can truly be safe. Really.
