Scientist in Frankenstein food alert is proved right

Accusations of cover-up after top pathologist backs the professor whose tests brought him humiliation

By Christopher Leake and Lorraine Fraser

The proffessor who was publically humiliated over claims that genetically modified ‘Frankenstein’ food may be harmful has been proved right after all. World expert Dr Arpad Pusztai was stripped of his post and described as ‘muddled’ by his superiors after he referred to experiments in which rats had been damaged when fed genetically-altered potatoes.

But today The Mail on Sunday can reveal that rats did suffer shocking internal damage. And we can disclose that a leading pathologist who has re-examined their remains has confirmed Dr Pusztai’s findings.

The scientific bombshell is sure to rekindle controversy over the safety of genetically altered food. The revelations will also place a question mark over the future of Dr. Putzai’s former boss, Professor Philip James, who ousted him from the research programme and is now being tipped as head of the Government’s new Food Standards Agency; due to be formed in April next year.

Dr Pusztai, 68, lost his job at the Government-funded Rowett Research Institute in Aberdeen after he told TV’s World In Action of his studies. The interview last August sparked a fierce debate on the potential dangers of genetically engineered food.

Yet Dr Pusztai was discredited for getting his facts badly confused by apparently referring to the wrong experiment. Professor James issued statements to the Press saying Dr. Pusztai ‘would have to retire’ because he had ‘got it wrong’ by suggesting the rats in question had been fed potatoes modified with genes from a bean — when, in fact, these particular experiments had never been carried out. The apparent mix-up - made amid the glare of TV publicity - cost Dr Pusztai his reputation.

But we can reveal that Dr Pusztai had conducted other crucial experiments using potatoes altered by another gene - and these tests demonstrated a worst case scenario. The tests were made on rats that were fed potato altered to carry a gene from snowdrops. This enabled the vegetable to make a chemical known as GNA lectin, which would protect it from insect and worm damage. The effect was devastating. Dr Pusztai’s results - contained in a report to Professor James and the Scottish Office - detail liver damage, even in rats fed cooked genetically modified potatoes for ten days.

His findings-seen by The Mail on Sunday - reveal that in most animals, ‘highly significant changes’ occurred in the weights of some or most of the rats’ vital organs and that immune system organs, like the spleen and thymus, were ‘frequently affected’.

Dr. Putzai's revelations have been backed by an independent analysis by consultant pathologist Dr Stanley Ewen, of Aberdeen University, who examined the preserved rats’ organs. Neither he nor Dr Pusztai will discuss their findings, which are expected to be published. But a leading expert said: ‘Dr. Ewen’s results will cause an explosion. These were measurable changes in the rats fed modified potato - and we feel there’s been a cover-up. There should be more openness in the whole business about public money and how it being used in this field.’

The doctors’ conclusions are a setback for the multibillion pound biotechnology industry, which is seeking licenses worldwide to grow high volume crops that resist herbicides.

At the start of the experiment, it was thought that snowdrop lectin was unlikely to produce harmful effects, so it would have been considered for commercial development. But now the revelations have thrown GM foods research into disarray.

After Dr Pusztai’s TV outburst Professor James - the man behind Government proposals for a Food Standards Agency - ordered an audit of Dr Pusztai a work by four scientists. It concluded that ‘existing data’ did not support the idea that the modified potatoes had ‘any effect on growth organ development or immune function’ in the rats. But the question being asked last night was why the report from the four scientists auditing the work do not analyse data on the rats’ internal organs which might have established if they had been damaged.

GM foods are already on supermarket shelves. An estimated 60 percent of processed foods on sale in the UK contain genetically modified soya grown in the US. Big business is pushing for licences to produce the crops in the UK, but at present only Government-approved test sites growing altered produce are permitted. And none of the crops is allowed to be sold to the public. A fortnight ago, the House of Lords Select Committee on

European Communities - to which Professor James gave evidence - acknowledged there were potential risks to the environment but said GM crops had much to offer.

The committee said the regulatory regime in place to ensure the safety of products sold in the shops was ‘thorough and proper.’

In oral eveidence to the same committee last October, Professor James alluded to ‘new data’ from Dr Pusztai - but he did not reveal its contents. Professor James said last night: ‘I am desperate that dear old Arpad Pusztai maintains his scientific credibility. I was interested in the GNA (snowdrop) data and told everybody - with the agreement of Pusztai, Scottish Office, Ministries, you name it - that this was important stuff and under no circumstances must we just have snippets coming out.’

He confirmed that the four scientists he had asked to audit Dr Pusztai’s claims did not have the full details of all the tests available to them. They considered the data available only up to the date of the World In Action programme. Professor James said he hadn’t disclosed Dr Pusztai’s new data to the Lords committee in October because ‘I am desperate to protect him. There is a standard policy in the scientific world that when there is something particularly of public interest and you have got something that could be of enormous significance, you must make sure your data is not only sound and robust but withstands review by your scientific peers.’
He said that if Dr Pusztai’s analysis was correct and the full feeding studies were repeated and produced the same findings, it would be ‘very important’. Paul Tyler, the Liberal Democrats’ food spokesman, said the new evidence raised a query over Professor James’s role as possible boss of the food agency. ‘The EU is more likely to be an effective watchdog on this issue than anybody in Britain, because successive governments have rolled over and had their tummies tickled by some of the huge multi-national companies involved in the research. I’ve seen no evidence yet that there is anybody in Whitehall to question in an effective way this sort of development.

‘Every time we get information about genetically modified organisms we see more evidence for a complete moratorium on further development of the programme until a lot more research has been done by a totally independent organisation.’

A Greenpeace spokesman said ‘As more research is done we’ll keep finding big problems. We don’t need to produce food this way ... so why are we taking these risks?’
