US inquiry finds no cases of GM wheat outside designated zone

The US Agriculture Department claims no cases of unapproved genetically engineered wheat have been found outside of a 123-acre field in Oregon after two months of investigation.

The discovery of the wheat, not approved for cultivation anywhere in the world, shook the global market when it was announced in May.

Some US customers in Asia and Europe halted purchases or said they would test incoming wheat shipments for biotech grain.
