However, it is also considered one of the food products most prone to be adulterated in the EU. Up until now, honey authenticity addressed mainly the issue of sugars addition and botanical origin. Still, increased attention has recently been paid to honey entomological origin as it also relates to its geographical origin since honeybees carrying mitochondrial DNA (mtDNA) of distinct ancestries can be found across Europe. While in Portugal mtDNA of the autochthonous subspecies Apis mellifera iberiensis belongs to the African (A) lineage, in the northeastern part of Iberia African mitotypes are replaced by mitotypes of western European (M-lineage) ancestry. The native distribution of the M-lineage A. m. mellifera expands from the Pyrenees to Scandinavia and from the British Isles to the Ural Mountains while the C-lineage A. m. ligustica and A. m. carnica subspecies are naturally found in the Apennine and Balkan peninsulas, respectively [1]. Also, certain honeys holding the protected designation of origin (PDO) label should be produced by autochthonous A. mellifera subspecies, as mentioned in their EU geographical indications register.engHoneyconference object
