If approved by the Food and Drug Administration (FDA), Atlantic salmon would be the first genetically engineered (GE) animal to be marketed in the United States for human consumption. Genetic engineering techniques are used by scientists to insert genetic material from one organism into the genome of another organism. Genetically engineered salmon have been modified to grow more quickly and use feed more efficiently. However, some are concerned that, in this rapidly evolving field, current technological and regulatory safeguards are inadequate to protect the environment and ensure that these products are safe to be used as food. This book discusses the genetically engineered salmon; the background of the techniques and the issues that go along with it.
