Eight samples of propolis commercially available on south-eastern Poland’s beekeeping market were compared in terms of quality, chemical composition and biological activity, including antioxidant and antimicrobial properties. The organoleptic characteristics and physicochemical requirements indicated that only 50% of tested propolis samples was classified to class II regarding obligatory limits, while the others were out-class. A big variation in mineral composition was determined by the ICP-OES method but all samples were free of heavy metals (Pb, Cd and Ni). Although mesophilic bacteria, yeasts and moulds occurred in tested propolis (in general lower than 102 CFU/g),
