Bioengineered food ingredients are those that contain genetic material that has been modified through certain laboratory techniques and for which the modification could not be obtained through conventional breeding or found in nature. These modifications are made using in vitro recombinant deoxyribonucleic acid (rDNA) techniques. Bioengineered foods or foods that contain bioengineered food ingredients must be labeled with the bioengineered food disclosure. The labeling is required for marketing purposes and does not convey any information about the health, safety, or environmental attributes of that food compared to non-bioengineered counterparts. Highly refined ingredients (like some sugars and oils) and foods that are primarily meat, poultry, or egg products, do not require a bioengineered food disclosure. Food sold by very small food manufacturers and food served in restaurants, food trucks, trains, airplanes, delicatessens, and similar retail food establishments are not required to provide a bioengineered food disclosure.
