"Just a few months ago, Mountain Equipment Co-op, a popular retailer of outdoor gear in Canada, pulled polycarbonate Nalgene bottles from its shelves. Now the Canadian government has banned baby bottles made from this clear plastic because there are indication that Bisphenol A (BPA), a chemical used in its production and which leaches out of the plastic, may be potentially quite harmful."

Now might be the time to look into other alternatives. I enjoy Klean Kanteen; the stainless steel alternative to plastic.
