Uncertainties loom as Vermont GMO law takes effect

Mehuron's and other markets around the state have signs ready for bins containing bulk items notifying consumers whether they contain, may contain or do not contain genetically modified ingredients.

Industry groups including the Grocery Manufacturers Association have sued to block the Vermont law, arguing that the labeling requirement amounts to compelled speech in violation of the First Amendment.

GMA spokesman Roger Lowe said the group hopes Congress acts quickly on compromise legislation offered last week by Republican and Democratic leaders on the Senate Agriculture Committee.

"Since the state of Vermont has given companies 30 days to correct any alleged GMO labeling violations, the immediate impact, if any, on companies in July should be limited," Lowe said.

At the Hunger Mountain Co-op in Montpelier, which specializes in natural foods and local products, general manager Kari Bradley called it "frustrating" that a state law the co-op has supported since it was before lawmakers in Montpelier might be erased from the books by federal action.
