GM food toxins found in the blood of 93% of unborn babies

Toxins implanted into GM food crops to kill pests are reaching the bloodstreams of women and unborn babies, alarming research has revealed.

A landmark study found 93 per cent of blood samples taken from pregnant women and 80 per cent from umbilical cords tested positive for traces of the chemicals.

Millions of acres in North and South America are planted with GM corn containing the toxins, which is fed in vast quantities to farm livestock around the world – including Britain.

However, it is now clear the  toxins designed to kill crop pests are reaching humans and babies in the womb – apparently through food.

It is not known what, if any, harm this causes but there is speculation it could lead to allergies, miscarriage, abnormalities or even cancer.

To date the industry has always argued that if these toxins were eaten by animals or humans they would be destroyed in the gut and pass out of the body, thus causing no harm.

Food safety authorities in Britain and Europe have accepted these assurances on the basis that GM crops are effectively no different to those produced using conventional methods.

But the latest study appears  to blow a hole in these claims  and has triggered calls for a ban on imports and a total overhaul of the safety regime for GM crops and food.

Most of the global research which has been used to demonstrate the safety of GM crops has been funded by the industry itself.

The new study was carried out by independent doctors at the Department of Obstetrics and Gynaecology, at the University of Sherbrooke Hospital Centre in Quebec, Canada.

They took blood samples from 30 pregnant women and 39 other women who were not having a baby.

They were looking for residues of the pesticides associated with the cultivation of GM food.

These include so-called Bt toxins, which are implanted using GM techniques into corn and some other crops.

Traces of Bt toxin were found in the blood of 93 per cent of the pregnant mothers – 28 out of 30. It was also found in 80 per cent of the umbilical cords – 24 out of 30.

In the non-pregnant group, traces were found in the blood of 69 per cent – 27 out of 39. It is thought the toxin is getting into the human body as a result of eating meat, milk and eggs from farm livestock fed GM corn.

The Canadian team told the scientific journal Reproductive Toxicology: ‘This is the first study to highlight the presence of pesticides associated with genetically modified foods in maternal, foetal and non-pregnant women’s blood.’

They said the Bt toxin was ‘clearly detectable and appears to cross the placenta to the foetus’.

Calling for action, the team said: ‘Given the potential toxicity of these environmental pollutants and the fragility of the foetus, more studies are needed.’

The director of GM Freeze, an umbrella group for community,  consumer and environmental organisations opposed to GM  farming, described the research as ‘very significant’.

Pete Riley said: ‘This research is a major surprise as it shows that the Bt proteins have survived the human digestive system and passed into the blood supply – something that regulators said could not happen.

‘Regulators need to urgently reassess their opinions, and the EU should use the safeguard clauses in the regulations to prevent any further GM Bt crops being cultivated or imported for animal feed or food until the potential health implications have been fully evaluated.’

The Agriculture Biotechnology Council, which speaks for the GM industry, questioned the reliability and value of the research.

Its chairman, Dr Julian Little, said: ‘The study is based on analysis that has been used in previous feeding studies and has been found to be unreliable.’

He said the toxins found are also used in other farming systems and gardening ‘with no harm to human health’.

Dr Little said: ‘Biotech crops are rigorously tested for safety prior to their use and over two trillion meals made with GM ingredients have been safely consumed around the world over the past 15 years without a single substantiated health issue.’

Toxin from GM crops found in human blood

Toxin from GM crops found in human blood

 


Fresh doubts have arisen about the safety of genetically modified crops, with a new study reporting presence of Bt toxin, used widely in GM crops, in human blood for the first time.

Genetically modified crops include genes extracted from bacteria to make them resistant to pest attacks.

These genes make crops toxic to pests but are claimed to pose no danger to the environment and human health. Genetically modified brinjal, whose commercial release was stopped a year ago, has a toxin derived from a soil bacterium called Bacillus thuringiensis ( Bt).

Till now, scientists and multinational corporations promoting GM crops have maintained that Bt toxin poses no danger to human health as the protein breaks down in the human gut. But the presence of this toxin in human blood shows that this does not happen.
 
Scientists from the University of Sherbrooke, Canada, have detected the insecticidal protein, Cry1Ab, circulating in the blood of pregnant as well as non-pregnant women.

They have also detected the toxin in fetal blood, implying it could pass on to the next generation. The research paper has been peer-reviewed and accepted for publication in the journal Reproductive Toxicology. The study covered 30 pregnant women and 39 women who had come for tubectomy at the Centre Hospitalier Universitaire de Sherbrooke (CHUS) in Quebec.

None of them had worked or lived with a spouse working in contact with pesticides.

They were all consuming typical Canadian diet that included GM foods such as soybeans, corn and potatoes. Blood samples were taken before delivery for pregnant women and at tubal ligation for non-pregnant women. Umbilical cord blood sampling was done after birth.

Cry1Ab toxin was detected in 93 per cent and 80 per cent of maternal and fetal blood samples, respectively and in 69 per cent of tested blood samples from non-pregnant women. Earlier studies had found trace amounts of the Cry1Ab toxin in gastrointestinal contents of livestock fed on GM corn. This gave rise to fears that the toxins may not be effectively eliminated in humans and there may be a high risk of exposure through consumption of contaminated meat.

"Generated data will help regulatory agencies responsible for the protection of human health to make better decisions", noted researchers Aziz Aris and Samuel Leblanc.

Given the potential toxicity of these environmental pollutants and the fragility of the foetus, more studies are needed, particularly those using the placental transfer approach, they added Experts have warned of serious implications for India. Cottonseed oil is made from seeds of genetically modified cotton and thus Bt toxin may have already entered the food chain in India.

"Indian regulators should be immediately called for detailed toxicological studies to know the extent of contamination of the human blood with Bt toxins coming from cottonseed oil, and also ascertain its long term health impacts," Sharma said.
