The US Department of Agriculture is investigating the discovery of genetically engineered wheat in an Oregon field, as an outcry mounted today among consumer groups and Japan suspended some US imports.
US regulators said the wheat carries no risks but the outcome of the probe — namely finding out whether such wheat is growing elsewhere — could have a wider impact on world markets, experts said.
“No one wants genetically engineered wheat,” said Bill Freese, science policy analyst at the Center for Food Safety, recalling that massive opposition in 2004 led seed giant Monsanto to pull back from its bid to commercialise it.
GE wheat is not approved for commercial sale anywhere in the world, but some herbicide-resistant plants were found in April on an Oregon farm, triggering a Government investigation, officials announced on Wednesday.
Market jitters ensued as Japan cancelled a bid for 25,000 tonnes of US wheat and the European Union told its member states to test imports from the area, saying any genetically modified wheat would not be sold to consumers.
Monsanto’s share price was down 3.3 per cent at $101.53 in mid-day trade after climbing for the past 10 days.
The altered wheat is glyphosate resistant, which means it contains a transgene that allows it to survive when a popular weedkiller made by Monsanto, called Roundup, is sprayed on fields.
The GE wheat was tested at more than 100 sites in the US from 1998 to 2005, but the last approved field trials in Oregon were in 2001, according to the USDA’s Animal and Plant Health Inspection Service (APHIS).
Monsanto said it was cooperating with the probe and vowed to “conduct a rigorous investigation to validate the scope of and to address any presence of a Monsanto Roundup Ready event in commercial wheat seed.”
The same GE technology is already widely used in soyabeans and maize in the US and allows farmers to spray their fields with weedkillers without harming the main crop.
“The first thing to know is it is perfectly safe. It was fully tested by Monsanto prior to 2005,” said Ronnie Coffman, Professor of plant breeding and director of international programmes of the College of Agriculture and Life Sciences at Cornell University.
