Senate passes bill that could put QR code labels on GMO foods

The Senate this week voted to approve a bill that would require foods with genetically modified ingredients to have those ingredients labeled, Reuters reports. It will now head to the House of Representatives, where it's expected to pass as well. Te bill has proved controversial for several reasons, on both sides of the GMO labeling debate. The first reason is one that's been brought up in the debate over labeling in general: the science suggests GMOs are safe to eat, and any bill is unnecessary, critics argue.
