You may soon find genetically-altered salmon on your dinner plate. For the first time ever, the FDA ruled a lab-engineered animal food product safe for people to eat. Genetically modified fruits and vegetables have been widely sold for more than two decades. This week, regulators approved a Massachusetts biotech firm’s fish that grow twice as fast as ordinary farmed salmon, thanks to added genetic material. They also said the salmon meets the definition of a drug. Some consumer and environmental groups fiercely oppose the move. They argue there hasn’t been enough research to determine whether the fish is safe… And say it could pose a risk to wild salmon populations. It’s not clear when the salmon will hit store shelves.
