Volunteer wheat from a field two miles away owned by the same farmer and planted with the same seed was tested and it was not found to be glyphosate-resistant. Monsanto was liable for fines of up to $1 million, if violations of the Plant Protection Act were found.[51][52] According to Monsanto it was "mystified" by its appearance, having destroyed all the material it held after completing trials in 2004 and because they did not think that seed left in the ground or pollen transfer could account for it.[50] Later in the month, Monsanto suggested that the presence of the wheat was likely an act of "sabotage".[53] The discovery could have threatened U.S. wheat exports, which totaled $8.1 billion in 2012; the US is the world's largest wheat exporter.[52][54] New Scientist reported that the variety of wheat was rarely imported into Europe and doubted that the discovery of the wheat would affect Europe, but more likely destined for Asia. As a result of the discovery of the unapproved strain, Japan and South Korea halted wheat orders from the United States, leaving wheat growers in neighboring communities unable to decide what to plant next season.
