There are some long term concerns about GE crops (I mentioned some of them in another thread something), but this is not that. Basically the "FrankenFood" stuff is pure hysteria. But not all concerns are hysteria, and the funny thing is the real concerns are hardly mentioned in the hysterical arguments.
Anyway, I love field corn better than sweet corn, and I have eaten BT and Roundup Ready corn on the cob and creamed every year for several years, now. So I'm living proof that GE food won't hurt you.
Well, on second thought, maybe I'm not such a good example.
