FDA keeping us safe?

I posted this link because I believe that you can see two very distinct discourses at work. You have the discourse of the FDA telling us that our food is safe. The fact they have put their stamp of approval on products at our local grocers can ensure that what we are consuming is safe and uncontaminated. And for so many Americans,  we have believed this to be true. It hasn't been until as of late that a new voice is rising up with a different belief system. There is a new movement in America of people who want to shed light on the truth about food, where it comes from, and more importantly, whether it's safe or not. This is the second discourse that we see which is being sounded out by filmmaker by Robert Kenner in this documentary, Food, INC.
