Can the mold from a water bottle harm you?

[Dianyla]

indigo, what do you know about this new bPA-free polycarbonate? Is it safe?

I've picked up a few of the bisphenol-a free bottles and I like them a lot. They are also taste-free, which is a big plus.

Especially if you, um, accidentally forget about them and mold grows in them. Once they've been cleaned out they really truly smell/taste clean again. This is in stark contrast to all of the traditional water bottles I've used - once those pick up a mold stink/flavor, it is never gone. Yech.

Back to the OP's question... if you're not actually allergic/sensitive to mold, it probably won't cause you any harm. It's just a little grotty. *shrug*
