Whether you think GMO foods are a threat to health or not, they should be labeled so that those who care can make the choice. I applaud them for raising this issue.
Foods need to be labeled GMO? Just about everything you eat has been genetically modified at some point in time. Do you want that labeled on everything you buy? Seems meaningless to me, but I'm sure you have your emotions,...er, I mean reasons.
The FDA only requires labeling if a food raises questions related to nutrition or safe use. People who understand the science involved are still waiting for those legitimate questions about the differing nutritional content and safety of GMO food. There's a lot of noise, but no there, there.
Beyond that though, labeling mandates based solely on an alleged consumers right to know, rather than on a products measurable characteristics, is in violation of the Constitution.
You are not allowed to demonize a product, or to create fear about a product, unless you can prove that there is a problem with the nutrition or safety of that product. But that's exactly what you want to do even though you have absolutely nothing to support you. Thank goodness more rational people are in charge.
