Arlene, I wish I could expand your new avatar! Very horn-of-plenty!
I agree that the total panic of many packaging companies proves that they KNOW that many people will panic if they find out that they've been eating food with ingredients from GM crops for years.
My threshold of concern is whole plants or animals. Oil from GE corn or sugar from GE sugar beets or cane (whichever it is) don't worry me. Feeding bt or RU-Ready grain to cattle and pigs doesn't worry me assuming farmers keep a close eye on their herds.
But I'm wary of eating sweet corn or salmon with genes spliced from bacteria, myself. No evidence, just wariness.
Concern about the environment is different, but I think that risk has already been taken and it's too late to close the gate.
