I received a very nice response (already!) from Lundberg Farms - we often buy their organic brown rice cakes and organic long and short grain brown rice. They directed me to their website, where they are "tracking" and responding to this particular issue. For those of you that are interested in their comments and what they're doing to insure that their products remain GMO-free, here is the link. You can then click on the links under the September date for more information.
