On October 8, 2007 the results of a study published in the Proceedings of the National Academies of Science (PNAS) suggested the potential for Bt corn to have effects on aquatic ecosystems in corn producing regions.
Scientific and regulatory authorities have acknowledged the potential risks associated with genetic modification of all kinds, including traditional cross-breeding, biotechnology, chemical mutagenesis and seed radiation, and have established a safety assessment framework for biotech crops designed to identify any potential food, feed and environmental safety risks prior to commercial use. The insect-protected Bt corn event MON 810 was rigorously assessed for safety by authorities prior to commercial introduction in 1997, and has been extensively studied by independent scientific experts before and after commercial approval.
Monsanto takes the benefits, stewardship and safety of all of our products very seriously. We are confident in the safety and benefits of Bt corn for humans, animals and the environment. While this study did not establish any field-level effects of Bt proteins on aquatic insects, it has raised questions that our scientific experts have carefully considered. These experts have thoroughly reviewed the publication and we have elected to make this review public to improve understanding of the study and its findings.
