Did you know that you probably eat GMOs every day? A genetically modified organism or GMO is an organism whose genetic material has been engineered or changed. Organisms that have been modified include plants, fish, mammals, bacteria, yeast and insects. Genetic modification involves the mutation, insertion, or deletion of genes. GMOs are created to resist pests, herbicides, harsh weather and improve a product's shelf life. Imagine what they can do to your body!
