A study was conducted to determine the extent of genetically modified (GM) protein from Roundup Ready Soybeans in tissues and eggs of laying hens. Because a breakdown of the modified portion of protein was expected due to the digestive process of the hen, an immunoassay test was run. By using a double antibody sandwich format specific for the CP4 EPSPS protein, a qualitative test was performed to determine the presence of modified proteins in various samples. Raw soybeans, soybean meal, complete diet, whole egg, egg albumen, liver, and feces from laying hens were collected from two independent commercial egg producers. Roundup Ready soybeans, soybean meal, and complete diets were determined to contain the GM proteins. Whole egg, egg albumen, liver, and feces were all negative for GM protein. In conclusion, the digestive process of the laying hen effectively broke down the GM protein from the soybean meal portion of the diet, hence no modified protein was found in the liver, egg, or feces in this brief field trial.
