There are only 10 GMO crops on the market in the U.S. The non-GMO label is a voluntary label that companies pay for. If a product does not have the non-GMO label, it does not mean that it contains ingredients from GMO sources. Varieties of the following 10 GMO crops are approved in the U.S.: apples, potatoes, field corn, sweet corn, canola, alfalfa, soybeans, rainbow papaya, cotton, sugar beet and summer squash. One addition is the recently approved AquAdvantage Salmon. So, if you see anything about GMO wheat, GMO tomatoes, or GMO popcorn, you can be sure it is false. In addition, non-GMO labels are not mandatory. Companies pay for non-GMO certification in order to be able to place the “non-GMO” label on a food package. These labels can be put on products that don’t even have a GMO counterpart; for example, you may see a non-GMO label on a bag of popcorn even though there is no GMO popcorn sold commercially in the U.S or anywhere else in the world.
