Simple answer, because it brings no more value to the product. Products are labeled non-GMO because they can charge more. Organic eggs in Indiana (labeled that way) sell for 4X the price of commercial eggs. What I find interesting is that these honest, hard working people-most raised by Amish families-feed GMO corn. Think about that when you label people with one huge brush.If GMO's are so wonderful, then why aren't they labeled? Why isn't the GMO industry proud of their accomplishments and why don't they proudly label their crowning achievements?
