A genetically modified organism (GMO) is a plant, animal, or microorganism whose genetic structure has been modified to express a desirable trait. The goal of genetic engineering (GE) in agricultural crops is to enhance flavor, improve nutritional qualities, produce higher crop yield, protect plants from insect pests, increase resistance to herbicides and diseases, and create plants with stronger tolerance to extreme environmental conditions. Similarly, genetic engineering can be applied in medical applications to develop targeted cell therapies, produce biopharmaceuticals in mass, and engineer mRNA vaccines.
Agricultural use of GE crops has steadily increased since its commercial introduction in 1996. In 2000, only 1-2% of planted acres of corn was of GE variety. However, by 2025, more than 90 percent of U.S. corn, upland cotton, and soybeans are produced using GE varieties. It is estimated that 75% of processed foods – from soda to crackers and condiments – contain GE ingredients.
Foods from GE crops must meets the same safety standards as foods derived from traditional selective breeding, according to The Food and Drug Administration, the U.S. Department of Agriculture (USAD), and the Environmental Protection Agency (EPA). Corn and soybeans are the most common GE crops in the U.S. and are often used as key ingredients in food products, such as corn starch, corn syrup, corn and soybean oil, salad dressings, bread, and easy snacks. In addition to corn and soybeans, other common GE crops include apples, canola, papayas, potatoes, and squash.
However, the marketing of GE medical or agricultural products is not without risks or potential consequences. These concerns are amplified by the fact that hundreds of companies, from small research boutiques to Fortune 500 chemical and pharmaceutical giants, are investing billions of dollars in GE applications.
