The American Medical Association called for mandatory pre-market safety testing of genetically engineered foods as part of a revised policy voted on at the AMA's meeting. Some activists concerned about foods made with genetically modified organisms had hoped the association would have gone so far as to support mandatory labeling of genetically engineered foods, but some still view the policy change as a major breakthrough. Currently biotech companies are simply encouraged to engage in a voluntary safety consultation with the Food and Drug Administration before releasing a product onto the market.
