The grains used are not certified organic. They are likely GMO seed designed to withstand being sprayed with RoundUp, ie RoundUp Ready genetically modified seed. They may also have genetically modified ability to within certain pests. Beyond that, even if there were a small portion of the feed that was not GMO, still, the farmer that grew that corn or wheat or milo or oats or soybeans relied on chemicals both as weed killers and pest control with pesticides.
It is possible, if ever soooooo slim a fraction, that a wee wee bit of the seed was completely free of such things, still, the farmer and his farm may not have ever taken the steps to certify as organic. The possibility of this last example would be extremely remote. Purina buys feed grains by the train car load, many, many train car loads. They want good clean grain, no doubt, but organic certified it just isn't. Hope that helps.
