The adoption of genetically engineered (GE) crop varieties by U.S. farmers is widespread for major crops—94 percent of planted acres for soybeans, and 88 percent for corn in 2012 (USDA-NASS 2012). The potential exists for GE crop production to impose costs on organic and conventional non-GE production via unintended presence of GE material along the supply chain through: • Contamination of seed stock • Accidental cross-pollination • Accidental co-mingling during planting, harvesting, handling, and storing of crops (Bullock and Desquilbet 2002). Maintaining the integrity of GE-differentiated product markets relies on segregation protocols such as: • Hybrid selection and seed purity testing • Physical distancing during crop production • Equipment cleaning and product segregation during processing • GE-testing (Greene and Smith 2010).
