Silenced genes, edited genes, algae engineered to produce compounds that taste like food: new genetically modified organisms (GMOs) made with these experimental techniques are making their way to your dinner plate. It’s the next wave of genetic engineering, or GMOs 2.0.

Will we know if they’re in our food?

The new GMO labeling law passed by Congress and signed by President Obama has been widely panned by consumer groups because it allows companies to use QR codes or 800 numbers in place of plain English on labels.

But even worse news for our right to know what’s in our food: vague wording in the new law opens the door for industry pressure on the U.S. Department of Agriculture to exempt many – possibly even most – GMOs from labeling at all.

To learn more about GMOs 2.0 and whether these foods will be labeled, I spoke with Michael Hansen, PhD, senior scientist at Consumers Union.
