Marilyn: How do you feel about genetically modified foods? How can we be sure they are safe?

I feel fine about genetically modified foods. And in this country, I feel confident in the zealous over-protection of our Food and Drug Administration, which oversees these foods. We don't know anything that they don't already know.
