In the United States, GM food products must be rigorously tested before they can be sold—far more so than conventionally bred crops. The testing process can take 7-10 years, and must include evaluations of potential risks to humans and livestock as well as potential risks to wildlife and the environment.
Part of the testing includes nutritional analysis and protein analysis and characterization. In these studies, researches look at the proteins and peptides expressed in the bioengineered organism compared to the original. This allows researchers to identify any new proteins created by the GM crop that could produce an allergic reaction or other adverse effect. Battelle helps companies conduct many of the required studies, including allergen testing for GMO products.
