It�s just a matter of time before we are eating clones, if
we are not eating them now.
When Canadian agricultural leaders asked Agriculture
Secretary Tom Vilsack last month, after a scandal about unlabeled clone
products in Europe, if �cloned cows or their offspring have made it into the
North American food supply,� he said, �I can�t say today that I can answer your
question in an affirmative or negative way. I don�t know.�
And when a reporter asked the USDA if cloned products are
already in the food supply, a spokesman said the department was �not aware of
an instance where product from an animal clone has entered the food supply�
thanks to a �voluntary moratorium�-- but that
offspring of clones, at the heart of the Europe scandal, �are not clones and
are therefore not included in the transition.�
Sounds like Europe is not the only place eating milk and
meat from unlabeled clone offspring. In fact, the BBC, UK newspapers and even a
US grocer all report that US consumers are digging into clone food, whether or
not they know it.
Like bovine growth hormone and Roundup Ready crops, the
government says clone products are so safe they don�t need to be labeled. But
the 2008 FDA report, Animal Cloning: A Risk Assessment and a report from the
European Food Safety Authority, released at the same time, raise questions
about the health of cloned animals, the safety of their milk and meat and even
the soundness of the clone process itself. To clone an animal, �scientists
start with a piece of ear skin and mince it up in a lab. Then they induce the
cells to divide in a culture dish until they forget they are skin cells and
regain their ability to express all of their genes,� writes the Los Angeles
Times� Karen Kaplan. �Meanwhile, the nucleus is removed from a donor egg and
placed next to a skin cell. Both are zapped with a tiny electric shock, and if
all goes well the egg grows into a genetic copy of the original animal.�
So far so good, except that it turns out many clones lack
the ability to �reprogram the somatic nucleus of the donor to the state of a
fertilized zygote,� says the FDA report and be the perfect replica a clone is
supposed to be.
The reprogamming problem, called epigenetic dysregulation,
means many clones -- some say 90 percent -- are born with deformities, enlarged
umbilical cords, respiratory distress, heart and intestine problems and Large
Offspring Syndrome, the latter often killing the clone and its �mother,� the
surrogate dam. Clones that survive epigenetic dysregulation often require
surgery, oxygen and transfusions at birth, eat insatiably but do not
necessarily gain weight and fail to maintain normal temperatures, admits the
report.
While denying that such dysregulation is endemic to cloning,
the FDA report nonetheless reassures readers that �residual epigenetic
reprogramming errors that could persist� in clones will �reset� over time. The
errors will also �reset� in offspring who, though �the same as any other
sexually-reproduced animals,� may nonetheless have them. Oops.
The FDA report, written in collaboration with Elizabethtown,
PA-based Cyagra and Austin, TX-based ViaGen, another clone company, tries hard
to talk around these and other clone problems. Too hard.
Although clones� calcium, phosphorus, alkaline phosphatase
and glucose levels exceed those seen in normal animals, �all of the elevations
can be explained by the clones� stage of life or stress level, and the
increased levels observed do not represent a food consumption risk,� says the
report.
The �slight mammary development� in a 4-1⁄2 month old Jersey
calf? Such precociousness �sometimes occurs in conventional heifers if they are
overfed.�
The rats fed cloned meat and milk who exhibited greater �frequency
of vocalization,� a signal of emotional response? It was probably �incidental
and unrelated to treatment,� says the report.
Cloned samples that show �altered� fatty acid composition
and delta-9 desaturase in the meat itself? �No comparisons were made with
historical reference values for either milk or meat,� says the report. Maybe
the composition of all meat and milk has changed over the years!
Worse, the report relies on government regulation-as-usual
to catch clone aberrations in the food supply. Nutrition Labeling Requirements
will determine if clone milk is okay, says the report, since �determining
whether animal clones are producing a hazardous substance in their milk
although theoretically possible, is highly impractical.� (We can inject a
nucleus into an egg but can�t analyze milk?)
And the hapless and sick throwaways that are cloning�s
bycatch? Those animals won�t be a threat to the food supply says the FDA
report, because they die at birth. And if they don�t die but remain sickly,
they�ll be kept out the food supply by the same slaughterhouse inspectors who
kept out mad cows, Hallmark school lunch cows and E. coli. Bon appetit.
�According to the three standards used to determine if
cloned food is safe -- nutrition, toxicology and chemical composition -- eating
cancerous tissue or pus would also be safe,� Dr. Shiv Chopra, a veterinarian,
microbiologist and human rights activist told AlterNet when we asked about
cloned food safety. It is like the wide-scale and unlabeled bovine growth
hormone used to produce milk �in which a cow gene was inserted into E. coli,�
says Dr. Chopra -- a huge experiment conducted on the public.
Even meat and restaurant interests agree with Dr. Chopra in
written comments about cloning on the European Food Safety Authority (EFSA) web
site.
Despite the science, there is an �important limitation� to
cloning projections, says Coldiretti, Italy�s largest farming interest group: �The
impossibility to make prediction [sic] on a long term base. The �Inquiry into
BSE� [Mad Cow] shows how no scientists had been able to foresee the problems
connected to the practice of recycling animal proteins in herbivores� feeding.
The BSE prion needed around 50 years to develop.�
CLITRAVI, the Brussels-based European Association for the
Meat Processing Industry concurs. �In the light of EFSA�s own clearly expressed
concerns regarding animal health and animal welfare, we take the view that
further research is needed before offsprings of cloned animals are used for any
purpose whatsoever, including medical,� it wrote.
The US-based Union of Concerned Scientists agrees that more
research about cloning is necessary -- not to mention labeling. �The choice of whether
to purchase such foods should be in the hands of individual consumers, not the
government or the industry. Consumers will have such a choice only if the foods
are labeled,� says the 250,000-member nonprofit science group.
In defending cloning, the FDA, Big Meat and Biotech claim
its negatives are no worse than in vitro fertilization and other Assisted
Reproductive Technology (ART) techniques already entrenched in factory farms,
and that it will aid �world hunger.� Animal suffering is downplayed by simply
not counting the animals who don�t make it in final figures, leading the World
Society for the Protection of Animals to observe that welfare and mortality are
not just risks for surviving clones but effects that �occur in a large
proportion of surrogate dams and clones.�
While the FDA admits that clone calves that �die or are
euthanized due to poor health� are rendered into animal feed byproducts that
present �possible risks� to food animals and the people who eat them, it is
less worried about healthy clones. Healthies are �unlikely� to be used for
human food �given their potential value as breeding stock� or even used as
animal food, �except through rendering of dead clones that occurred at
parturition or by accident.�
Since the first cloned mammal, Dolly the sheep, was created
in 1996, cloning has become more common and causes less outrage than new
Frankenfoods like the Enviropig with its roundworm gene and AquAdvantage salmon
with its Chinook salmon gene (both moving toward FDA approval.) But whether it�s
become common in our food no one can know -- because it�s unlabeled. And could
be anywhere.
