Begin by sharing information with others. Then, contact grocery store managers, school cafeterias and local restaurants and encourage them to take a stand against genetic engineering by refusing to carry such products. If no market exists for these foods, manufacturers won't continue producing them. Additionally, Fagan recommends pressuring your state legislators to introduce bills mandating testing and labeling. Encourage manufacturers of your favorite products to label foods.
Tests do exist to determine if an item has been engineered.
For instance, Genetic ID, a test produced in the United States, determines whether items such as soybeans at the raw level have been genetically engineered. Fagan suggests shopping carefully. Products to watch for include canola oil, tomatoes, yellow crook-necked squash, cheeses and some juices containing genetically engineered enzymes, products such as cola or jam containing corn syrup, soy products, and bread products containing dough conditioner. Soy is present in 60 percent of all processed foods, according to Fagan. The Natural Law Party, a political party, expresses the following concerns regarding genetic engineering of foods.
