GMO contamination widespread throughout the U.S. food supply:  

Shoppers wary of GM Foods Find They're Everywhere
You may not want to eat genetically engineered foods. Chances are, you are eating them anyway.
Genetically modified plants grown from seeds engineered in labs now provide much of the food we eat. Most corn, soybean and cotton crops grown in the United States have been genetically modified to resist pesticides or insects, and corn and soy are common food ingredients.
The Agriculture Department has approved three more genetically engineered crops in the past month, and the Food and Drug Administration could approve fast-growing genetically modified salmon for human consumption this year.
Agribusiness and the seed companies say their products help boost crop production, lower prices at the grocery store and feed the world, particularly in developing countries. The FDA and USDA say the engineered foods they've approved are safe — so safe, they don't even need to be labeled as such — and can't be significantly distinguished from conventional varieties.
Organic food companies, chefs and consumer groups have stepped up their efforts — so far, unsuccessfully — to get the government to exercise more oversight of engineered foods, arguing the seeds are floating from field to field and contaminating pure crops. The groups have been bolstered by a growing network of consumers who are wary of processed and modified foods.
Many of these opponents acknowledge that there isn't much solid evidence showing genetically modified foods are somehow dangerous or unhealthy. It just doesn't seem right, they say. It's an ethical issue.
"If you mess with nature there's a side effect somewhere," says George Siemon, CEO of Organic Valley, the nation's largest organic farming cooperative, which had more than $600 million in sales last year. "There is a growing awareness that our system makes us all guinea pigs of sorts."
The U.S. government has insisted there's not enough difference between the genetically modified seeds its agencies have approved and natural seeds to cause concern. But Agriculture Secretary Tom Vilsack, more so than his predecessors in previous administrations, has acknowledged the debate over the issue and a growing chorus of consumers concerned about what they are eating.
