The potential health effects of meal and oil processed from seed of genetically modified (GM) canola plants (OECD unique identifier: DP-Ø73496-4; hereafter referred to as 73496 canola) containing an insert that expresses the GAT4621 protein conferring tolerance to nonselective herbicidal ingredient glyphosate were evaluated in a subchronic rodent feeding study. Sprague–Dawley rats (12/sex/group) were administered diets containing dehulled, defatted toasted canola meal (DH meal) and refined/bleached/deodorized canola oil (RBD oil) processed from seed of plants that were untreated (73496), sprayed in-field with glyphosate (73496GLY), the non-transgenic near-isogenic (091; control), or one of four commercially available non-GM reference canola varieties (45H72, 45H73, 46A65, 44A89). All diets were formulated as a modification of the standard laboratory chow PMI® Nutrition International, LLC Certified Rodent LabDiet® 5002 (PMI® 5002). DH canola meal and RBD canola oil replaced all commodity soybean fractions typically incorporated in PMI® 5002. No toxicologically significant differences were observed between the test and control groups in this study. The results reported herein support the conclusion that DH meal and RBD oil processed from seed of 73496 canola are as safe and nutritious as DH meal and RBD oil processed from seed of non-GM canola.
