French agricultural sectors are opposing the Mercosur agreement, warning it could have detrimental structural effects on the entire agri-food chain from production to marketing. They are urging the French government to use its veto at the EU Council to block the agreement, citing concerns over food sovereignty and environmental issues. The sectors also want mirror clauses in existing agricultural import agreements and increased controls on imports to ensure they meet European regulations. They argue that without these measures, imported products pose a risk to food safety and compete unfairly with European production.
