The Senate just voted to usher in nationwide mandatory labeling of genetically modified foods.

The bill, passed Wednesday with strong Republican support, requires food companies to tell consumers if there are any genetically engineered ingredients in their products. Companies wouldn’t necessarily need to do that by writing “contains GMOs” on the package — they could provide that information with a scannable QR code and small businesses could comply by simply providing a phone number or website.

Republicans did most of the heavy lifting: 47 voted for the measure along with 18 Democrats, giving it enough votes to withstand a filibuster.
