This document discusses genetically modified foods (GMOs) and provides information on both sides of the debate around their safety. While some studies have shown GMOs are as safe as traditional foods, others have found harmful effects in animals. The scientific community has concerns about a lack of independent studies and influence of industry interests. Standards have been established by the USDA to require labeling foods as bioengineered. The document provides brief overviews of the production of bioengineered alfalfa, apples, and canola.
