President Barack Obama signed the GMO labeling bill on July 29, 2016. This historic bill will require the mandatory labeling of food that contains genetic engineering. The legislation gives food producers the option to either label their products with wording or a symbol, or to provide a smart phone accessible digital QR code that when scanned, discloses information concerning whether the food contains ingredients made with biotechnology. The newly signed law will preempt a potential patchwork of state-based GMO labeling laws that could’ve caused chaos in the national food manufacturing and distribution system. With the President’s signature, the next step will be implementation of a national labeling system by the U.S. Department of Agriculture.
