An Oregon farmer has been found by the U.S. Department of Agriculture with a form of genetically modified wheat that was never approved for use in the United States.

Biotechnology company Monsanto, which recently received special dispensation from the federal government for other products, developed the particular strain of modified wheat but it was kept from being put into use after worldwide outcry against genetically modified wheat.

The last time the wheat was used in a field test was in 2005. The last time it was allegedly used in Oregon was 2001.

The farmer reported the wheat to the USDA after it was growing too fast in an unexpected place and didn’t die off when sprayed with the herbicide Roundup.
