Abstract

Crops produced through genetic modification are beginning to reach the market and many genetically-modified crops are under development. Since genetic modification results in the introduction of new proteins into the food plant the safety of the newly introduced proteins must be assessed. The potential allergenicity of the newly introduced protein is a major consideration in that safety assessment. All allergens are proteins but only a few of the many proteins found in foods are allergenic. The assessment of the allergenicity of the newly introduced proteins should focus on the source of the gene, the sequence homology of the newly introduced protein to known allergens, the immunochemical reactivity of the newly introduced protein with IgE from the blood serum of individuals with known allergies to the source of the transferred genetic material, and the physicochemical properties of the newly introduced protein.
