Franken-Salmon Approved by FDA

The U.S. Food and Drug Administration (FDA) approved the first genetically engineered animal, a breed of Atlantic salmon that grows twice as fast as normal salmon. Genetically altered crops that are resistant to drought and pests have been around for years. The new salmon grow fast because they secrete increased amounts of growth hormone. The salmon will have no special labeling, so consumers will not know whether they are getting normal or super salmon. Critics are concerned about the risks of these salmon contaminating the natural fisheries. More genetically altered animals are on the horizon, including cattle without horns and pigs that do not need to be castrated. (Nature, 527:417-418, 2015)
