What The Science Really Says About GMOs And Food Safety

The U.S. has a new federal law that will, for the first time, require labeling of genetically modified ingredients in food. President Barack Obama signed the bill into law Friday, and the secretary of agriculture has two years to finalize the labeling standard. 

The new law, which was largely supported by the food industry, puts the U.S. in line with 64 other countries that also require manufacturers to label genetically modified foods. Two-thirds of Americans also support labeling GMOs. But while labels for genetically modified foods might seem sensible — or at the very least, harmless — the issue obscures some very important facts about the GMO debate.
