Passage
One
Forty
to sixty percent of genetically modified organisms are finding
their way to the produce departments. That process involves
taking a gene from one plant or animal and putting it in
another. "So now, we make these changes in the laboratory
and put these changes back into corn by the new technology,"
Dr. Curtis Hannah said.
Not all consumers are pleased that researchers
are tinkering with food that finds its way to American dinner
tables. Opponents say that some produce is laced with pesticide
to make them drug resistant.
Labeling advocate Jodette Green said that
foods that have been genetically engineered need to be labeled.
A Massachusetts watchdog group said that
a local supermarket chain is selling a pancake mix containing
genetically engineered ingredients that aren't listed on
the label.
News Center 5's Rhondella Richardson reports
that MassPIRG launched its Safe Food Campaign on Thursday,
calling for accurate labeling and better testing of genetically
modified food.
MassPIRG said that packages of Shaw's Pancake
Mix contain GM food, but they aren't labeled as such. "There's
no info about the potentially dangerous DNA contained in
this pancake mix," Jill Rubin of MassPIRG said at an afternoon
press conference.
Cereal and many soy and corn products are
genetically modified, but they often don't say so on the
label. There are not rules or regulations requiring such
information on nutrition labels.
MassPIRG believes that childhood ear and
sinus infections could soon be incurable and that the consumption
of genetically engineered food creates more food allergies.
Shaw's pancake mix has not caused any known
health problems, but many feel that better labeling shouldn't
be too hard for a store to swallow. "I want to know what's
in everything I buy," shopper Alexander Grieco said. "I
have high blood pressure and high cholesterol."
MassPIRG targeted Shaw's Supermarkets in
its campaign because the Shaw's parent company in London
has voluntarily removed all genetically engineered ingredients
from its store brand products.
A local Shaw's spokesperson said that in
England, there was a lack of direction from the government
on what to do when consumers questioned product safety.
The Food and Drug Administration has found nothing unsafe
so far, and Shaw's awaits direction from the FDA before
any product is recalled.

Passage
Two
Today, the average American eats 19 pounds of fresh tomatoes
and 73 pounds of processed tomato products each year. The
fresh-tomato market alone has grown into a $5-billion-a-year
industry. Still, most Americans complain about the wet-cardboard
taste of out-of-season supermarket tomatoes.
In 1989 biologist Athanasios Theologies
and his colleagues at the U.S. Agricultural Research Service
in Albany, Calif., tackled the problem of restoring the
hearty, vine-ripened flavor to supermarket tomatoes. The
challenge: tomatoes harvested green to prevent bruising
and spoilage during shipment don't produce the natural ripening
gas, ethylene. Even when these green tomatoes are artificially
ripened with ethylene, the immature fruit lacks the complex
brew of sugars and acids that makes homegrown tomatoes so
tasty.
Theologies and his team located the gene
that triggers ethylene production. They manipulated the
genetic sequence using "splicing techniques" and reinserted
it into the DNA of the tomato cells. In theory this would
prevent the test tomato from producing ethylene on the vine.
They waited tensely while the genetically
engineered tomato plant bore its first green fruit in the
laboratory hot-house. As they had hoped, the tomato remained
on the vine long enough to develop its intricate flavor
components without the softening caused by ethylene.
The bioengineering process they patented
led to the Endless Summer tomato. When picked, these tomatoes
remain tough enough for safe shipment. Endless Summer tomatoes
are then exposed to ethylene gas in warehouses, where they
turn red and tender. They stay plump and fresh-tasting for
almost four weeks.
Plant breeders constantly search for tomatoes
that are virus-, drought- and cold-resistant, and the U.S.
Department of Agriculture is tracking over 2000 distinct
varieties. Supersteaks, for instance, can weigh several
pounds. The world record for the heaviest tomato goes to
Gordon Graham of Edmond, Okala., for a seven-pound, 12-ounce
Delicious.
There are good reasons besides taste for
eating tomatoes. According to a Harvard University study,
a diet rich in tomatoes—whether eaten raw in salads or
puréed in a sauce—might dramatically decrease the risk
of prostate cancer. The key to the tomato's possible cancer-fighting
ability, according to Harvard's Dr. Edward Giovannucci:
the antioxidant lycopene.

Passage
Three
A French author, George Perec, once wrote a 300-page novel
without using the letter e. To write a 5 000-word manifesto
on the "new economy" without once using the word America,
or even the words United States, cannot have been much easier,
but the European Union's leaders were equal to the task
when they met in Lisbon last week.
At the end of a summit devoted mainly to
"employment, economic reform and social cohesion", they
produced an 18-page blueprint for "radical transformation
of the European economy", chock-a-block with digital literacy
and the like. But admit that Europe is learning from A******?
No, thanks. Europe will build its new economy "in a manner
consistent with its values and concepts of society", i.e.,
slowly and late.
One big reason European leaders do not mention
America in their document may be that they hope to leave
vague the embarrassing cause of their onrush of liberalism.
As the American economy has gone on growing, as the American
stock market has refused obstinately to crash, and as the
dollar has humiliated the euro, so the Europeans have found
their long-accumulating envy of the American boom turning
into mild panic. They fear that the United States is pulling
so far ahead of them in growth, and investment, and technology,
and power, and prosperity, as to deny Europe all hope of
catching up for generations at least. Something must be
done or, at least, said.
And plenty of it, apparently. The policy
recommendations from Lisbon cascade down through 41 numbered
paragraphs. A purist might have found it reassuring if the
words private sector had merited more than a single mention,
in paragraph 41. But there are plenty of steps, or at least
promises to take steps, in the right direction. The governments
have promised to deregulate their markets in telecoms, financial
services, transport and energy; to spend more on adult education;
to encourage scientific research; and to support new Internet
infrastructure. Even France, the main foot-dragger, claims
it is arguing only about the timing, not the principle,
of liberalization. There are brave attempts, by E.U. standards
at least, to attach firm dates for carrying out some of
the changes; and nowhere does the document call for the
setting-up of any new bureaucracy, a remarkable achievement—again, by E.U. standards—in itself. Instead, heads of
government will regroup for further summits each spring
to check on progress.
