LePage  said until  scientists can prove BPA is harmful, the state should not  rush to  restrict its use.
  
 "BPA is one of the most well-studied chemicals, and it  is just ludicrous  to ignore the science," said Susan Shaw, a  toxicologist at the Maine  Environmental Research Institute who has been  studying the effects of  toxics on humans and animals for more than  three decades. "There is a  large body of evidence about the hazards of  BPA that is irrefutable."
