Monsanto officials held a press call on Friday regarding “suspicious” evidence in the investigation of genetically engineered wheat plants found in an Oregon field last month that suggests it was possibly intentionally planted.

“The evidence now collected, the fact patterns established and the original Roundup Ready CP-4 event appearing suddenly after 12 years, out of nowhere in a single field in the state of Oregon is highly suspicious,” said Monsanto Vice President and Director of Technology Robb Fraley, stressing that they don’t know the grower or the field or have the plant samples available. However, “the more data we generate, the more clarity we’re getting on this, and the more suspicious it looks.”

When pressed by reporters, Fraley said, “It’s fair to say that there are folks who don’t like biotechnology and would use this as an opportunity to create problems.” He also pointed to the recent destruction of two sugar beet fields in the state of Oregon by anti-GMO activists.
