Organic is Usually GMO Free
Buying 100% Organic, Certified Organic, and USDA Organic-labeled products is usually the easiest way to identify and avoid genetically modified ingredients.
The United States and Canadian governments do NOT allow companies to label products 100% / Certified Organic if they contain genetically modified foods.
To put it in more detail:
100% Organic: Must contain 100 percent organically produced ingredients (excluding water and salt). This is the only label that certifies a completely organic product AND completely GMO-free ingredients.
Certified Organic / USDA Organic: At least 95 percent of content is organic by weight (excluding water and salt). The <5% remaining ingredients must consist of substances approved on the USDAs National List. GMOs are NOT on this list, so USDA Organic products are also usually GMO-free.
