On September 18, the U.S. Food and Drug Administration released guidance on a regulatory framework for approving the entrance of genetically modified (GM) animals into the nation's food supply. The term "guidance" is agency-speak for the law will look something like this. Put another way, the FDA has offered advice, considerably weaker than legally enforceable regulation. With the announcement, a 60-day period for public comment was opened.
The only GM animal currently licensed for sale in the U.S. is the glow-in-the-dark zebra fish, a pet. With the exception of a few drunk frat boys, this fish is not expected to be consumed by humans, and its need for warm water precludes any possibility of it escaping into the wild. But the glowing zebra fish will soon have some GM company in stores near you.
The new guidance is primarily directed at animals genetically modified for food-production purposes, but it's based on the approval process used for animals that are genetically modified for pharmacological purposes, such as pigs designed to grow human livers, or goats that produce insulin in their milk. Under the guidance, all GM animals, be they of the farm or pharma variety, will be classified as drugs.
Technically, the drug is the bit of foreign DNA that's spliced into the animal's cells, and the FDA will grant or deny approval to just those bits of DNA, not to the whole organism. This creates a dangerous regulatory gray area, says Jaydee Hanson, a policy analyst at the Center for Food Safety, who calls this arrangement a "fiction."
"The gene is in every cell of the animal, and regulating the animal is the only tool they have to control these genes, but they say they're only regulating the gene, not the animal," he says. "Drugs don't get loose and breed with each other. Animals do."
As a case in point he mentions the "AquAdvantage" line of GM salmon created by Aqua Bounty Technologies of Waltham, Mass., in 2001. The regulated "drug" in this case is a gene that makes salmon secrete extra growth hormone, causing the fish to reach maturity in 18 months instead of 30.
Should any of these fish escape into the wild, they would take their recombinant genes with them, posing unknown -- and therefore, Hanson says, unacceptable -- risk to wild salmon stocks and the ecosystems they inhabit.
It's rumored that AquAdvantage salmon will be the first GM food animal approved for sale by the FDA. Meanwhile, a growing number of GM animals are being developed for the food market, says Hanson, and given this fact he thinks an approval process is long overdue. But while steps toward the creation of a regulatory framework for GM food animals are steps in the right direction, he says the FDA's guidance as currently written leaves much to be desired.
