The battle, at long last, is effectively over now as President Obama signed federal GMO labeling legislation into law one week ago today. The law, which has been working its way through Congress for the past few years, requires food manufacturers to notify consumers of the presence of GMOs in packaged foods by one of three specific methods – a text label, a label with a specific symbol, or an electronic bar code that is readable by smartphones. With the President’s signature, the legislation, which opponents referred to as the DARK Act (Deny Americans the Right to Know), prevents a state-by-state patchwork of mandates and wipes out the far more stringent Vermont GMO labeling law that took effect July 1 of this year. Vermont Senators Patrick Leahy and former democratic Presidential candidate Bernie Sanders were ‘berned’ by the President’s signature as they both vehemently opposed the legislation. The US Department of Agriculture will now have 2 years to write and finalize regulations providing for the implementation of the national labeling requirement.
