So where exactly might you find a GMO label if it existed? 1.GMOs or foods containing GMOS This is obvious. Actual whole GMO produce such as pest-resistant sweet corn, or disease-resistant squash would be labeled. Processed foods obviously containing these ingredients such as salsa with GM corn or trail mix with dried GM papayas would also be labeled. 2.Meat/Dairy from animals fed GMOs This is a bit trickier, and still up in the air. As Ben and Jerry’s points out on their website, eating a GMO does not make YOU a GMO. For this reason, they have advertised that their ice-cream is “GMO free” for years, even though it is made from the milk of cows fed genetically modified feed. This logic seems fair enough. After all, the gene that makes alfalfa a GMO cannot be found in a pint of Cherry Garcia. 3.Processed foods made with oil/sugar extracted from GMOs As with meat/dairy, this is a toughy. Just as the genes unique to GMOs don’t make it through a cow’s gut, they also don’t show up in high-fructose corn syrup or soybean oil. These processed ingredients are 100% identical to organic alternatives. 4.Foods produced by (or with ingredients produced by) GM microorganisms The production pipeline of some foods and food additives relies on genetically modified fungi or bacteria. Cheese is pretty much universally made using enzymes produced by genetically modified microorganisms. Genetically modified microorganisms can also produce vitamins, which can then be used to fortify cereals. This might explain why several vitamins went missing when Grape Nuts and Cheerios went GMO-free. The GM microorganisms themselves are not present in the final product, so the only difference is a decrease in vitamin A, B12, D and Riboflavin in the GMO-free version.
