MONTPELIER — The Vermont attorney general’s office is flashing the yellow caution light as lawmakers consider a bill that would mandate labeling of foods made with genetically modified organisms.

The House Agriculture Committee took testimony for the first time this year on a GMO labeling bill and heard words of caution from Assistant Attorney General Bridget Asay.

She told the committee on Wednesday that a Vermont labeling law almost certainly would draw a lawsuit or lawsuits from the food industry, and she said the outcome of such suits would be very uncertain.

She said the industry likely would argue that Vermont was exaggerating the risks of foods containing GMOS, and that any labeling requirement would violate the First Amendment.
