A Republican congressman from Kansas introduced legislation on Wednesday that would nullify efforts in multiple states to require labeling of genetically modified foods

The bill, dubbed the "Safe and Accurate Food Labeling Act" was drafted by U.S. Rep. Mike Pompeo from Kansas, and is aimed at overriding bills in roughly two dozen states that would require foods made with genetically engineered crops to be labeled as such.

The bill specifically prohibits any mandatory labeling of foods developed using bioengineering.
