For the first time, consumers will be able to find out whether or not their food contains genetically modified organisms (GMO).

On Thursday, the U.S. House of Representatives passed legislation calling for a federal mandatory labeling standard of foods containing GMOs by a vote of 306-117, ending the long-standing debate over how and if food products should be labeled. The legislation, passed in the Senate last week, now awaits the approval of President Barack Obama. The White House says the president is expected to sign the bill.
