Honey represents a pleasant, nourishing food, with great biological and calorical value (315 kcal/100 g), easily digestible. It possesses real bactericidal properties, due to inhibin content. Examination of honey is necessary in order to assess its quality and purity, as well as to identify forbidden substances. The study was conducted in a processing unit which markets honey in the European Community. This study aimed to evaluate the contamination degree of the commercialised honey. In the summer of 2019, 3 batches of honey were analyzed (2 acacia honey batches containing 15 samples each and 1 batch containing 15 samples of polyfloral honey). Laboratory assessments were focused on determination of nitroimidazoles residues (metronidazole, dimetridazole, ronidazole), tetracyclines (oxytetracycline, tetracycline, chlortetracycline, doxycycline, demeclocycline, methacycline, minocycline), macrolides (clindamycin, erythromycin, josamycin, kitasamycin, lincomycin, oleandomycin, spiramycin, mirosamycin,tilmicosin, trimethoprim, tylosin), nitrofuran metabolites, chloramphenicol, streptomycin, dihydrostreptomycin, sulfonamides, trimethoprim, glyphosate. The methods used in the research were HPLC, LC-MS/MS, ELISA. The final results of the study that considered the a forementioned batches, sampled from various local beekeepers, proved that antimicrobial drug residues were in accordance with the national and international regulations, permitting marketing without restrictions.
