While any US new station (possibly with the exception of NPR) will be sensationalized and alarmist, as someone who studies primate (and we are primates) nutrition, I am completely behind banning substances until we find that they are harmless. Additionally, some of the comments below are simply stupid: (1) "Innocent until proven guilty" is a great right for humans, but it should not apply to products. I am quite sure you'd be complaining if radio-active substances had been considered "innocent until proven guilty" and released to the public for their use pending testing. This did happen with arsenic laced green dyes (not radioactive, but same story), and in the case of the Radium Girls/Women. (2) If we were to assume "innocent until proven guilty" then these chemicals could still be "banned" until found not guilty (just as humans can be retained/jailed until trial if they are deemed potentially harmful).
