Thanks
to the biotech industry’s relentless quest to control our food,
McDonald’s, Burger King and even school cafeterias will soon be able to
serve up apples that won’t turn brown when they’re sliced or bitten
into. A new, almost entirely untested genetic modification technology,
called
RNA interference,
or double strand RNA (dsRNA), is responsible for this new food miracle.
Scientists warn that this genetic manipulation poses health risks, as
the manipulated RNA gets into our digestive systems and bloodstreams.
The biotech industry claims otherwise.
Of course, like any
non-organic apple, the new GMO Arctic® Apple will be drenched in toxic
pesticide residues, untested by the U.S. Food & Drug Association
(FDA) and likely unlabeled. And of course these shiny new high-tech
apples will be cheap, priced considerably lower than a pesticide-free,
nutrient-dense, old-fashioned organic apple that turns a little brown
after you slice it up.
When the Biotech Industry Organization gathers next week in Chicago for the 2013
BIO International Convention,
BIOTECanada will present its “Gold Leaf Award for Early Stage
Agriculture” to Okanagan Specialty Fruits, Inc. (OSF), purveyor of the
Arctic® Apple, slated for approval in the U.S. this year. We hate to
upset the biotech apple cart, but a pesticide-intensive GMO apple,
produced through a risky manipulation of RNA, doesn’t deserve a place on
our grocery shelves, much less in the agriculture hall of fame.
That
said, the Arctic “Frankenapple” is expected to be approved this year by
the U.S. Department of Agriculture (USDA), responsible for protecting
agriculture from pests and diseases. It does not require approval by the
FDA, which is responsible for human food and animal feed.
Just one more bad apple
Apples,
that is, apples that haven’t been certified organic, already are on the
list of Should-Be-Forbidden fruits. They reliably top the Environmental
Working Group’s
Dirty Dozen list,
for both the volume and the stunning array of pesticides consistently
found on them. According to the Pesticide Action Network’s
analysis of the most recent USDA data, apples tested positive for 42 pesticides, including
organophosphate
and pyrethroid pesticides. Both are endocrine disruptors, both have
suspected neurological effects, and both are considered especially toxic
for children. (
Organophosphates are the basis for nerve gases used in chemical warfare, and have been
linked to the development of ADHD in kids.)
Given
the grim report card of non-organic apples, some might say it really
doesn’t make any difference if we start tinkering with the apple’s
genetic RNA. After all, unlike the case with GMO corn or salmon,
scientists aren’t injecting pesticides or genes from foreign plants or
animals into the genes of apples to create the Frankenapple. While most
existing genetically engineered plants are designed to make new
proteins, the Arctic Apple is engineered to produce a form of genetic
information called double-stranded RNA (dsRNA). The new dsRNA alters the
way genes are expressed. The result, in the Arctic Apple’s case, is a
new double strand of RNA that genetically “silences” the apple’s ability
to produce polyphenol oxidase, an enzyme that causes the apple to turn
brown when it’s exposed to oxygen.
Harmless? The biotech industry,
OSF and some scientists say yes. But others, including Professor Jack
Heinemann (University of Canterbury, New Zealand), Sarah Agapito-Tenfen
(from Santa Catarina University in Brazil) and Judy Carman (Flinders
University in South Australia), say that dsRNA manipulation is untested,
and therefore inherently risky. Recent research has shown that dsRNAs
can transfer from plants to humans and other animals through food.
The
biotech industry has always claimed that genetically engineered DNA or
RNA is destroyed by human digestion, eliminating the danger of these
mutant organisms damaging human genes or human health. But many biotech
scientists says
otherwise.
They point to evidence that the manipulated RNA finds its way into our
digestive systems and bloodstreams, potentially damaging or silencing
vital human genes.
There are indirect health consequences, too.
Turns out the chemical compound that is shut off in the engineered fruit
through RNA manipulation, in order to make it not oxidize or brown, is a
chemical compound that also fights off plant pests. What happens when
the apple’s ability to fend off insects is compromised? Growers will
need to spray greater amounts, of possibly even more toxic pesticides,
on a crop already saturated with at least 42 types of pesticides. Those
pesticides will eventually find their way into our bodies, either
because we ingested the fruit, or breathed the air or drank the water
where the pesticides were sprayed.
Testing? What testing?
So
what’s the trade-off? Non-organic apple growers will prosper as more
moms buy more apples for more kids who will, the industry alleges, be
the healthier for it. It makes for a good public relations story, but
no matter how you wrap it up or slice it, taking apples that are already
saturated in pesticides, and genetically engineering them for purely
cosmetic purposes, does not a healthy snack make.
The pro- and
anti-GMO movements will debate whether or not the GMO apple is safe for
human consumption. The fact is, we’ll never know until they are properly
labeled and safety-tested. As with every other GMO food ingredient or
product sold in the U.S., the Arctic Apple will undergo no independent
safety testing by the FDA or the USDA. Instead, the USDA will rely on
OSF’s word that the apple is safe for human consumption. And without any
state or federal mandatory GMO labeling laws in place, OSF will not be
required to label its Frankenapple, meaning that consumers or children
harmed by the dsRNA modified apple will have great difficulty
identifying the mutant RNA that harmed them.
The controversy and
debate surrounding dsRNA and the Arctic Apple has just begun. But there
is no longer any debate about the dangers that pesticides and pesticide
residues on non-organic apples pose to humans, whether we directly
ingest these toxic residues by eating an apple, or whether we’re exposed
to them through contaminated air and groundwater as a result of acres
of orchards being sprayed to control increasingly resistant insects and
diseases.
What about the argument that a kid eating a few slices
of apples can’t consume enough of any one of these pesticides to cause
any real risk to their health? Debunked. Recent
studies
reveal that during apple season, kids exhibit spikes in the level of
pesticides found in their urine, spikes that exceed the U.S.
government’s “safe levels.” Kids who live in apple-growing regions show
even higher spikes. And those 42 varieties of pesticides? The government
establishes “safe levels” for each one – but it doesn’t test for the
potential effect of ingesting 42 different pesticides, all chemically
interacting with each other, and ingested all at once.
From biodiversity to monoculture
How
did we get to the point where it takes 42 pesticides to keep an apple
crop healthy? Michael Pollan best explains it in his book
Botany of Desire. Turns
out that apples have an extreme tendency toward something called
heterozygosity, which means genetic variability. This trait accounts for
how, left to its own devices, the apple can “make itself at home in
places as different from one another as New England and New Zealand,
Kazakhstan and California.” Pollan writes: “Wherever the apple tree
goes, its offspring propose so many different variations on what it
means to be an apple – at least five per apple, several thousand per
tree – that a couple of these novelties are almost bound to have
whatever qualities it takes to prosper in the tree’s adopted home.”
Today, you’d have to visit the apple orchard
museum
in Geneva, New York, to find all the varieties of apples that used to
thrive in the wild. Over time, in our quest to control the taste,
texture and appearance of apples, we’ve eliminated all but a relative
few varieties. We’ve gone too far, says Pollan. By relying on too few
genes for too long, the apple has lost its ability to get along on its
own, outdoors.
Enter the agro-chemical companies. According to the National Agricultural Statistics Service (NASS) Agricultural Chemical Use
Program,
apple growers in states surveyed in 2011 applied carbaryl to 46 percent
of their acreage, at an average rate of 1.566 pounds per acre for the
crop year; chlorantraniliprole to 45 percent; and chlorpyrifos to 44
percent. Apple growers applied glyphosate isopropylamine salt to 25
percent of acres at an average of 1.604 pounds per acre for the crop
year. And that’s just the tip of the iceberg.
The Arctic Apple has
been in development for over a decade, the company says. OSF submitted a
petition for deregulation to the USDA in May 2010. The USDA, which must
hold two public comment periods, concluded the first on Sept. 11, 2011.
It’s expected to open the second public comment period this spring or
summer, and OSF hopes the GMO apple will be approved for growing and
selling in the U.S. this year.
The Organic Consumers Association will hold a
press conference
and set up a picket line at the Biotechnology Industry Organization
Convention in Chicago, at noon on April 23, to protest OSF’s GMO apple.
