You may know that H.R. 1599, the "Safe and Accurate Food Labeling Act of 2015" passed the House of Representatives a couple of weeks back and has been referred to committee in the Senate. You may also know that the bill would ban states from requiring labeling of foods containing genetically engineered (GE) ingredients, and that its opponents have dubbed it the Denying Americans the Right to Know Act, or DARK Act. But what all is in the bill? More than you might think.
First, the basics. The bill passed the House of Representatives on July 23 by a vote of 275 to 150, with support from 94% of House Republicans and 25% of House Democrats. The engrossed (i.e., passed) House bill has been referred to the Senate Agriculture Committee, though there is as yet no corresponding Senate bill.
If enacted in its current form, the bill would, broadly speaking, do three things, only one of which focuses specifically on labeling of GE foods. First, it would define when GE plants can be sold for use in foods and preempt any state law restrictions on such sales. Second, it would limit the ability of food manufacturers to label their foods as either free from or containing GE ingredients, and it would preempt state labeling requirements for GE foods. And third, it would require development of federal standards for labeling foods marketed as "natural" and preempt state laws on that subject as well.
