Fears That Human-Genes Frankenfoods Will Spread*

There are Beans, Beans, Beans with human genes in the store........
THE ongoing controversy over genetically modified food is set to explode
again, with news that the first GM food crop containing human genes is
likely to be approved for commercial production.
The laboratory-created rice produces some of the human proteins found in
breast milk and saliva.
Its US developers say they could be used to treat children with
diarrhoea, a major killer in the Third World.
The rice is a major step in so-called Frankenstein Foods, the first
mingling of human-origin genes and those from plants. But the US
Department of Agriculture has already signalled it plans to allow
commercial cultivation.
The rice's producers, California-based Ventria Bioscience, have been
given preliminary approval to grow it on more than 3,000 acres in
Kansas. The company plans to harvest the proteins and use them in
drinks, desserts, yoghurts and muesli bars.
The news provoked horror among GM critics and consumer groups on both
sides of the Atlantic.
GeneWatch UK, which monitors new GM foods, described it as "very
disturbing".
Researcher Becky Price warned: "There are huge, huge health risks and
people should rightly be concerned about this."
Friends of the Earth campaigner Clare Oxborrow said: "Using food crops
and fields as glorified drug factories is a very worrying development.
"If these pharmaceutical crops end up on consumers' plates, the
consequences for our health could be devastating.
"The biotech industry has already failed to prevent experimental GM rice
contaminating the food chain.
"The Government must urge the US to ban the production of drugs in food
crops. It must also introduce tough measures to prevent illegal GM crops
contaminating our food and ensure that biotech companies are liable for
any damage their products cause."
In the US, the Union of Concerned Scientists, a policy advocacy group,
warned: "It is unwise to produce drugs in plants outdoors.
"There would be little control over the doses people might get exposed
to, and some might be allergic to the proteins."
The American Consumers Union and the Washingtonbased Centre for Food
Safety also oppose Ventria's plans.
As well as the contamination fears there are serious ethical concerns
about such a fundamental interference with the building blocks of life.
Yet there is no legal means for Britain and Europe to ban such products
on ethical grounds.
Imports would have to be accepted once they had gone through a
scientific safety assessment.
The development is what may people feared when, ten years ago, food
scientists showed what was possible by inserting copies of fish genes
from the flounder into tomatoes, to help them withstand frost.
Ventria has produced three varieties of the rice, each with a different
human-origin gene that makes the plants produce one of three human proteins.
Two - lactoferrin and lysozyme - are bacteria-fighting compounds found
in breast milk and saliva.
The genes, cultivated and copied in a laboratory to produce a synthetic
version, are carried into embryonic rice plants inside bacteria.
Until now, plants with human-origin genes have been restricted to small
test plots.
Ventria originally planned to grow the rice in southern Missouri but the
brewer Anheuser-Busch, a huge buyer of rice, threatened to boycott the
state amid concern over contamination and consumer reaction.
Now the USDA, saying the rice poses "virtually no risk". has given
preliminary approval for it to be grown in Kansas, which has no
commercial rice farms.
Ventria will also use dedicated equipment, storage and processing
facilities supposed to prevent seeds from mixing with other crops.
The company says food products using the rice proteins could help save
many of the two million children a year who die from diarrhoea and the
resulting dehydration and complications.
A recent study in Peru, sponsored by Ventria, showed that children with
severe diarrhoea recovered a day and a half faster if the salty fluids
they were prescribed included the proteins.
The rice could also be a huge money-spinner in the Western world, with
parents being told it will help their children get over unpleasant
stomach bugs more quickly.
Ventria chief executive Scott Deeter said last night: "We have a product
here that can help children get better faster."
He said any concerns about safety and contamination were "based on
perception, not reality" given all the precautions the company was taking.
Mr Deeter said production in plants was far cheaper than other methods,
which should help make the therapy affordable in the developing world.
He said: "Plants are phenomenal factories. Our raw materials are the
sun, soil and water."
