Brit Doctors' Association (BMA) sounds alarm on GM food


By Marie Woolf, Political Correspondent

Doctors will tell the Government this week that too little is known about
the long-term risks of eating genetically modified food to guarantee its
safety. They will warn that GM crops pose a potential threat to human
health and the environment.

The British Medical Association, which represents 115,000 doctors, will
say the crops should not be grown commercially in Britain until more
trials are carried out, arguing that the benefits must be clearly shown
before biotechnology companies are allowed to go ahead.

The BMA report, The Impact of Genetic Modification on Agriculture, Food
and Health, marks the first official opinion by a British medical body on
GM crops. It will call for more testing by independent scientists and for
the results to be freely available to the public.

The report, to be published on Tuesday, will say detailed research is
needed into possible toxicity of GM food and whether eating it could lead
to the development of new allergies and antibiotic resistance in humans.

It will reinforce pressure for a government-backed moratorium on the
commercial growing of GM crops in Britain.

The doctors will also cast doubt on the use of data from the United
States, where commercial GM crops are already grown, to predict
consequences for Britain. The threat of cross-pollination of GM plants
could be greater here because the country is smaller and fields are closer
together, the report says.

The findings of the BMA's board of science and education will stress that
consumers have a right to clear labelling. Its report will call for more
comprehensive labelling than the Government has proposed.

The most serious reservations concern lack of knowledge about health
implications. The doctors will express doubts about using antibiotic
resistance marker genes in GM plants, a common practice. They will call
for more rigorous investigations of the dangers of antibiotic resistance
and whether that could increase vulnerability to diseases such as

Two weeks ago, the Independent on Sunday revealed that the Chief Medical
Officer, Sir Liam Donaldson, and the Government's Chief Scientific
Adviser, Sir Robert May, had recommended that ministers set up a panel to
see if eating GM food could cause birth defects, the creation of new
cancers and damage to the immune system.

But their conclusions, which have been read by members of the ministerial
committee on genetic engineering, known as MISC6, are being amended by the
Government before the report is published.

This has infuriated MPs, who will this week urge Jack Cunningham, Cabinet
Office Minister, to publish the report in its original form. They accuse
ministers of a cover-up. "The original advice must not be sanitised, it
must be published without changes immediately," said Norman Baker, Liberal
Democrat environment spokesman.

Ministers fear the report could raise doubts about the Government's
handling of the safety issue. A cabinet document, seen by the Independent
on Sunday, warned as long ago as February that its conclusions on the
effects of GM foods on human health could be serious.

"At its last meeting, MISC6 requested a paper by the CMO/CSA [Chief
Medical Officer/Chief Scientific Adviser] on human health implications of
GM foods. Will we publish this when it is ready (c April) and use it as a
means to explain that GM foods on the market are safe?," the memo asks.

The paper, marked "Restricted - Policy", warns: "What if it shows up any
doubts? What can we do? We will be pressured to ban them immediately. What
if it says that we need evidence of long term effects? This will look like
we are not sure about their safety - we do not monitor consumption of
other foods."
