Since 1995, when Turtle Island Foods took an official stand against GMOs, they have made "every effort possible" to avoid them. Much of what the company produces is organic, and Turtle Island Foods is actually an "Organic Processor", certified as Oregon Tilth Certified Organic. According to the Cornucopia Institute, Turtle Island uses tofu sourced from 100% organically-farmed soybeans, and all manufacturing of products is done in the company's facility. The Green Stars Project awarded Tofurky 5/5 green stars for overall social and environmental impact.
