Abstract

The environmental risks and benefits of genetically modified crops have varying degrees of certainty. The U.S. regulatory system evaluates a suite of hazards for the crops primarily by minimizing type I error. However, genetically modified crops vary widely in their potential for environmental harm. We develop a differentiated risk assessment process using three models that shift from primary emphasis on controlling type I error for crops similar to conventionally bred varieties to stringent control of type II error for the most novel genetically modified crops. Parallel risk management approaches with economic considerations are discussed. Crop biotechnology development implications are drawn.
