It's official: the Canadian government has declared bisphenol-a (BPA) toxic, and has moved to ban sales of baby bottles, cups, etc. made from polycarbonate plastic, which leaches the chemical in normal use.
In addition, California, New York and Maryland are considering laws to ban sales of toys, child care and feeding products made with BPA. To no one's surprise, of course, the industry has filed suit against California arguing that federal law preempts California's action.
This is one of those times when caution should dictate our actions. With easily available alternatives, ditch those BPA bottles and cups and replace them.
