Safety Assessment Shows GA21 x T25 Maize as Safe as Conventional Counterpart

March 5, 2025

The Food Standards Agency (FSA) and Food Standards Scotland (FSS) released the results of the safety assessment on the genetically modified (GM) stacked GA21 x T25 maize for food and feed uses under assimilated regulation (EC) No. 1829/2003 (RP2023). The safety assessment is published in FSA Research and Evidence.

GA21 x T25 maize has been genetically modified to tolerate glyphosate and glufosinate ammonium herbicides through the introduction of the mEPSPS and PAT transgenes. The application, submitted by Syngenta Limited, seeks authorization for its import, processing, and use in food and feed and does not include cultivation in the UK.

FSA and FSS conducted a comprehensive safety assessment, reviewing molecular characterization, toxicity, allergenicity, and nutritional data, along with environmental risk advice from the Advisory Committee on Release to the Environment (ACRE). Based on their evaluation, the FSA and FSS concluded that GA21 x T25 maize is as safe as its conventional counterpart.
