Investigations continued this week into how unauthorized genetically modified wheat
Ended up on a farm in Oregon.
No varieties of GM wheat have been cleared for commercial use anywhere in the world.
The wheat plants in question are believed to be the legacy of a research programme that
Was abandoned nine years ago. How and Why they have resurfaced is unclear.
The discovery last week triggered an international reaction, with both South Korea and Japan
Temporarily suspending imports of US wheat. South Korea has also begun testing existing
Wheat imports from the US for signs of GM wheat, with no positive results so far.
