Frankenfish - modified salmon - considered for approval in US

WASHINGTON
U.S. government food regulators pondered Monday whether to say, for the first time, that it's OK to market a genetically engineered animal as safe for Americans people to eat.

The Food and Drug Administration is holding two days of hearings on a request to market genetically modified salmon. Ron Stotish, chief executive of AquaBounty, the company that made the marketing request, said at the meeting that his company's fish product is safe and environmentally sustainable.
Critics, however, call the modified salmon "frankenfish" that could cause the eventual decimation of the wild salmon population. An FDA advisory committee is reviewing the science of the genetically engineered fish this week and hearing such criticisms as the agency ponders approval.

The FDA has already said that the salmon, which grows twice as fast as conventional ones, is as safe to eat as the traditional variety.
Whether the American public will have an appetite for it is another matter. Genetic engineering is already widely used for crops, but the government until now has not considered allowing the consumption of modified animals. Although the potential benefits — and profits — are huge, many individuals have qualms about manipulating the genetic code of other living creatures.
Part of the two-day hearing will focus on labeling of the fish. It is possible that if the modified salmon is approved, consumers would not even know they were eating it. Current FDA regulations only require modified foods to be labeled as such if the food is substantially different than the conventional version, and the agency has said that the modified salmon is essentially the same as the Atlantic salmon.
Approval of the salmon would open the door for a variety of other genetically engineered animals, including an environmentally friendly pig that is being developed in Canada or cattle that are resistant to mad cow disease.
"For future applications out there the sky's the limit," said David Edwards of the Biotechnology Industry Association. "If you can imagine it, scientists can try to do it."
AquaBounty says it would be the first in the world to market genetically engineered fish.The company submitted its first application for FDA approval in 1995, but the agency did not decide until two years ago to consider applications for genetically engineered animals — a move seen as a breakthrough by the biotechnology industry.
Genetically engineered — or GE — animals are not clones, which the FDA has already said are safe to eat. Clones are copies of an animal. With GE animals, their DNA has been altered to produce a desirable characteristic.
In the case of the salmon, AquaBounty has added a growth hormone from a Chinook salmon that allows the fish to produce their growth hormone all year long. The engineers were able to keep the hormone active by using another gene from an eel-like fish called an ocean pout that acts like an on switch for the hormone, according to the company. Conventional salmon only produce the growth hormone some of the time.
