While the potato industry is lagging behind as far as human consumption goes, the use of potatoes as a raw material is booming. In fact, three-quarters of all the potatoes grown in Europe are used for something other than your dinner plate. Many of the other potatoes are fed to livestock, and the rest are for the alcohol and starch industries. That's a lot of vodka and dry cleaned shirts.
Scientists are beginning to make GM potatoes specifically intended to be grown and sold as starch potatoes. As far as potatoes that you might find in your grocery store, about 10 percent could be genetically modified. These are not just the raw, whole potatoes you'll find in the veggie section. You can also find GM potatoes in processed products containing potatoes.
