I have worked in the food production industry and have grown my own ducks, chickens and vegetables. I was the king of organic and I saw and tasted the results first hand. My eggs always had poop smeared on them. My kids refused to eat them because of that problem; even when I cleaned them in bleach water. They tasted the same as the store bought eggs because our local egg suppliers produce the best tasting eggs in the world.
I know that the processing of non-organic foods is the same as organic foods. There is much robotics that prevents that food worker sneezing on the produce. The difference is the chemicals used to keep the produce from insect infestation. I know from my own experience growing my own vegetables, that insects are a nuisance. Radishes would have grub worms in them, squash would have leaf mites, corn cobs would have some little devil that took out a few rows of kernels and so forth. Imagine the disappointment to cut open a cabbage head and find that grub worm burrowed inside. I still ate it, but I never found one from the grocery. I wonder how many of these Whole Foods customers are finding that grub worm as extra protein in their produce?
Seriously, these organic farmers who avoid insect control, cause the entire area to go out of insect control. Their neighbors have to ward off their insects that blow over to their fields. And, the insecticides they use to control them, get carried by the winds onto the supposed organic crops.
