The U.S. House of Representatives Thursday passed the Senate version of GMO labeling, sending the bill on to the White House and the expected signature of President Barack Obama. The legislation, which was the result of a compromise between Republican Senator Pat Roberts of Kansas and Senate Democrat Debbie Stabenow of Michigan, passed the house on a 306-117 vote. The House action follows last week’s action in the Senate, which voted 63 to 30 for passing the bill. The legislation mandates GMO labeling either on package or through smart labels. It also preempts state laws, such as the Vermont labeling law that went into effect July first. The House last year passed a voluntary labeling bill 242-185, but a similar measure failed to gain traction in the Senate earlier this year. A spokeswoman for President Obama said this week the President will sign the compromise GMO labeling bill.
