Analysis of the claim:

• The EPA has not made any public statement that Terrana Biosciences' modified soybeans are "not genetically modified organisms" according to an EPA spokesperson who explicitly stated the agency "has not made a public determination regarding Terrana Biosciences' RNA-based technology"¹.
• There is no credible evidence that the EPA has approved any Terrana Biosciences products for commercial agricultural use or made comments about whether the technology constitutes GMOs¹².
• Terrana Biosciences' RNA-based agricultural products remain in the research and development phase as of early 2026, with no commercial regulatory approvals¹².
• The EPA spokesperson noted that RNA-based crop sprays are generally regulated as pesticides, and importantly clarified that the USDA governs labeling of bioengineered foods, not the EPA¹.
• While Terrana's technology uses RNA rather than traditional genetic modification of the plant genome, the specific claim that the EPA has officially declared these soybeans "not GMO" is unsupported and contradicts the EPA's own statements²¹.
• Social media posts making similar claims about EPA approval and "not GMO" determinations have been investigated and found to contain false information¹².
