The renewal of authorization for genetically modified maize T25 is contested due to insufficient assessment of long-term risks to health and the environment. The maize is resistant to glufosinate, a herbicide banned in the EU, raising concerns about increased pesticide residues. The lack of evidence on cumulative effects contradicts the precautionary principle and the 'One Health' approach. Approval could disadvantage EU farmers by allowing imports that do not meet domestic standards. A reform of the authorization process is demanded to address democratic deficits and lack of member state support.
