It’s taken nearly 20
years but AquAdvantage salmon will soon be served in restaurants and appearing
at your local fish counter. AquAdvantage is a man-made breed of salmon that’s
part Atlantic salmon and part Chinook salmon with a few genes from other fish
thrown in that rev up the animal’s growth processes so they’re active most of
the year, as opposed to only part of the year. With these changes,
AquaAdvantage’s developer, AquaBounty Technologies, says the salmon grow at
twice the rate of farm-raised fish.
The approval by FDA is
controversial and contested. Here’s what you need to know for now.
Is the genetically
modified salmon safe to eat?
The Food and Drug
Administration says it “rigorously evaluated extensive data submitted by the
manufacturer, AquaBounty Technologies, and other peer-reviewed data…” and
determined that it “is safe to eat by humans and animals.”
Most studies on animals
that are fed genetically modified foods don’t show serious health effects,
though there are a few that hint at potential harm to organs like the kidneys,
liver and heart, as well as increased risk of cancers and early death in these
animals.
Will I know which
salmon is genetically modified and which are not?
Not necessarily. There
is no regulation requiring that AquaAdvantage fish be labeled as being
genetically altered fish. Any labeling would be voluntarily by the companies’.
The FDA issued two recommendations asking manufacturers to voluntarily label
their products, along with guidance about how to note the genetic changes.
Some groups are calling
for mandatory labeling. Scott Faber, executive director of a campaign called
Just Label It said this in a statement: “The decision to approve GMO salmon
without a mandatory disclosure is yet another example of how FDA’s outdated policy
keeps consumers in the dark.”
Is it the first
approved GMO animal approved for sale in the United States?
Yes. But up to 80% of
the processed foods sold in the U.S. contain GMOs, mostly from plant crops.
Corn, soy, potato and even some apple crops are genetically engineered to
either produce more or to resist insects and drought. (See here for a chart of
these crops.)
Why are some people
against GMOs?
There are three major
concerns about changing genes in wild plants or animals. First, the alterations
could change the plant or animal in ways that could be harmful for people who
eat them. The changes could also harm the plant or animal and make them less
fit to survive. Finally, on a broader level, introducing new hybrid species
could alter the environment in unpredictable and potentially worrisome ways. ‘
In the salmon’s case,
if the genetically altered fish were to make its way into rivers and oceans, it
could outcompete the wild salmon, which is smaller, for food and breeding
grounds.
What if the GMO salmon
gets into the wild somehow?
For now, AquaBounty
says that’s unlikely to happen since it plans to grow AquAdvantage in
land-based tanks. The company will also use only female fish that are sterile
so breeding in the wild is also unlikely.
But some
environmentalists point out to NPR that the company’s egg production facility,
on Prince Edward Island, is near an estuary that feeds into the ocean and that
the fish will be allowed to mature in a location in Panama that is located near
a river, making escape a remote but nevertheless real possibility.
Will changing the genes
harm the fish?
The data isn’t clear on
this yet. While AquaBounty’s president once told Reuters that AquAdvantage is
“an Atlantic salmon in every measurable way,” studies by researchers who have
compared genetically modified salmon to their wild counterparts have shown that
the fish behave differently. The genetically altered fish tend to eat more to
support their growth-promoting genes, and prefer spending time near the surface
of the water alone, as opposed to swimming in groups. They also show some
reduced immune functions.
Where will the
genetically modified salmon be sold?
AquaBounty says it may
take as long as a year to raise enough fish to supply supermarkets. But certain
retailers, including Whole Foods, Trader Joe’s and Aldi, have said in the past
that they will not sell the genetically modified fish.
