Official basis (Method): Annex VI explicitly lists Fehling reagent among staining mounting media. Use the specified workflow and validated interpretation.
Procurement note: Use the selected Annex VI preparation and mounting system. Reagent detection does not by itself identify source species or establish legal feed permissibility.
