What does this mean for your pet and how can you feed foods that are GMO free? The answer is to read labels and ask questions of food producers. Anything labelled organic will be GMO free by definition. Avoid soybeans, canola, cottonseed, corn, and sugar from sugar beets. These are the crops with the highest prevalence of GMO. Remember too that there are many byproducts of these crops, especially corn, such as syrup, starch additives. Many companies are now labeling their products that are GMO free.

In general, fresh organic ingredients will provide the best chance of avoiding genetically engineered foods. Companies that do not use genetically modified ingredients will typically make that obvious on their packaging. Remember – pay attention, read labels and ask questions if labels are unclear. The time you spend will be worth the health benefits to you and your pets.
