Whether it's a fast-growing fish species or a new crop of corn, the questions surrounding genetic engineering boil down to some common elements. Genetic engineering, however, has led some people to think twice.
Some people develop allergic reactions to certain foods, such as shellfish and peanuts.
These allergic reactions, in severe circumstances, can kill. Proteins that are taken from commonly allergenic foods are presumed to be allergens unless tests indicate otherwise. These foods must be labeled. Proteins taken from foods that are not commonly allergenic must also be evaluated. If these proteins have the characteristics of allergens, they too must be labeled unless tests indicate that they do not cause allergic reactions.
