Agricultural biotechnology refers to a range of tools—including genetic engineering and some conventional breeding techniques—to genetically modify living plants, animals, microbes, and other organisms for agricultural uses (e.g., food, feed, fiber). The term commonly refers to recombinant DNA techniques that introduce desired characteristics into target organisms, predominantly pest and herbicide resistance in crops. It also encompasses a range of new genome editing technologies (e.g., CRISPR-Cas9) that manipulate genetic material at precise locations in the genome. Most genetically engineered (GE) agricultural products are crops—in the United States, the only GE animals currently approved for human consumption are the AquAdvantage salmon and the GalSafe pig.
