Genetically modified (GM) plants used for food and feed have an established history of safe use over more than 25 years of their commercialization. Developers and regulatory authorities have accumulated extensive experience in evaluating their safety over time. The studies required for the safety assessment of GM plants used for food and feed should now be re-defined to leverage this experience and increased scientific knowledge. This paper, a companion paper for Waters et al. also published in this issue, present…

Summary Data requirements are not harmonized globally for the regulation of food and feed derived from stacked genetically modified ( GM ) events, produced by combining individual GM events through conventional breeding. The data required by some regulatory agencies have increased despite the absence of substantiated adverse effects to animals or humans from the consumption of GM crops. Data from studies conducted over a 15‐year period for several stacked GM event maize ( Zea mays L.) products (Bt11 × GA 21, Bt11 …
