Mon810 maize and teosinte: hybridisation still unmonitored
For several years, EFSA and ANSES have been asking Bayer to monitor the emergence of teosinte, the wild ancestor of maize, in fields cultivated with Mon810 maize in Portugal and Spain. In 2023, the company was still not doing so. However, the presence of teosinte in Europe has been confirmed. A scientific study has even shown experimentally that the Mon810 transgene can be transmitted from maize to teosinte plants collected in Spanish fields. The production of transgenic insecticidal protein is therefore not under control.
