GM Pea Causes Death

A decade-long project to develop genetically modified peas with built-in pest-resistance has been abandoned after tests showed they caused allergic lung damage in mice.

The work underlines the need to evaluate new GM crops on a case-by-case basis, says Paul Foster of the Australian National University in Canberra, who led the immunological work. He also calls for improvements in screening requirements for genetically engineered plants, to ensure comprehensive tests are carried out.

Jeremy Tager, Greenpeace Australia’s campaigner on genetic engineering, agrees. “These results indicate the potential for unpredicted and unintended changes in the structure of transferred proteins. And I’m not aware of any country that requires feeding studies as part of its approval process.”

He adds that slight differences in protein synthesis might also occur in other plants with other genes, meaning each new GM food should be very carefully evaluated for potential health effects. “If a GM plant is to go up for human consumption, there should be a detailed descriptive list of how one should go about analysing that plant,” he says.

Tager agrees. It is rare for an investigation of the potential health effects of a GM product to be published in a peer-reviewed journal, he adds. “If it had been a private company doing this, it might never have seen the light of day,” he says.
