On Friday, President Barack Obama signed national biotech disclosure into law, which now requires USDA to draft rules within two years to establish labeling and disclosure standards that could include using scan codes on packaged foods as well. The law also preempts states from establishing separate standards, such as the Vermont genetically engineered labeling law that went into effect in July, but is now superseded by the new act.

“President Obama’s signature today will put a stop to the harmful patchwork of state GMO labeling laws and set in place a uniform, national disclosure system that will provide balanced, accurate information to consumers,” AFBF President Zippy Duvall said in a statement. He also pointed out that for decades, biotechnology has made it possible for farmers to grow safe and healthful crops while reducing their environmental impact.

“We are pleased that Congress and the administration have moved swiftly to prevent consumer confusion and protect agricultural innovation,” Duvall concluded.
