Genetically-engineered salmon are one step closer to the supermarket. Following a 2010 report that GE salmon is safe for human consumption, the Food and Drug Administration has just announced the fish also pose no environmental threat.

Nicknamed "frankenfish" by detractors, AquAdvantage salmon contain genes that allow them to grow twice as fast all year long. They would be the first GE animal to make its way into the United States food supply, and, if approved, the salmon would not have to carry a label informing the consumer it is genetically modified.

Some opponents fear the fish could get loose from farms and breed with the wild supply. Others argue there has not been enough long-term testing to determine GE foods do not pose a threat to human health.
