Does MSF use GMO (Genetically Modified Organism) feed for their cattle?
The short answer is: "No".
The longer answer is: "We try not to, but without GMO labelling on products, and restrictions on the reproduction of GMO products, we can't be sure."
Also, because we avoid mono-culture pastures (pastures and hayfields with only one or two species of grass), it is easier to avoid GMO plants. The assumption being that any GMO product will be crowded out by other plants.
