Four key liability issues can be identified and at least partially quantified: first, the potential for volunteer GM seed (seed inadvertently left in a field after harvest) to germinate the following year (s); second, the potential for pollen flow from GM crops to non-GM crops; third, the potential for co-mingling of GM and non-GM crops (this could jeopardize the value both of the crop in some markets and of downstream foods, products, or product lines if transgenes remain undetected before processing); and fourth, the potential for environmental risks associated with uncontrolled gene flow from GM varieties into related plants to impede export of GM varieties to nations that do or do not want to adopt the new technologies.
