Advocacy group calls on Coca-Cola and Pepsi to label genetically modified ingredients

According to the United Nation's Food and Agriculture Organization (FAO), contamination of GMO-free traded foods by GMO crops is on the rise. Of 198 instances of low-level contamination between 2002-2012, 138 occurred between 2009-2012.

“The incidents have led to trade disruptions between countries with shipments of grain, cereal and other crops being blocked by importing countries and destroyed or returned to the country of origin,” writes FAO in a report on the topic.

Flax seed, rice, corn and papaya were the most commonly contaminated foods.
