Determination of quinolones, macrolides, sulfonamides and tetracyclines in honey using QuEChERS sample preparation and UHPLC-MS/MS analysis
Monitoring beehive health and timely prevention of possible infections by bacteria, mould, viruses or parasites is exceptionally important in beekeeping. Antibiotics originating from the environment can be found in honey and due to improper beekeeping practices. Enabling the detection of antibiotic residues in honey and suppressing the development of antibiotic resistance require the development of a sensitive multi-class method for the determination of antibiotics. For the purpose of analysing honey, a screening and confirmatory method for the determination of 36 antibiotics was developed. The QuEChERS procedure and ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was selected to achieve high sensitivity and selectivity. Validation according to the new Commission Implementing Regulation (EU) 2021/808 included the following performance characteristics: selectivity, trueness, precision, decision limit (CCα), detection capability (CCβ) and relative matrix effect. The method was validated in the measurement range from 1 to 10 μg/kg, where maximum trueness and acceptable coefficients of variation were achieved. The detection capability (CCβ) equals the lowest concentration level for all analytes, ranging from 0.1 μg/kg to 2.5 μg/kg, as the false compliant rate less than 5% was confirmed at this level of interest. For unauthorised pharmacologically active substances, the CCα was determined and ranged from 0.16 μg/kg for sulfaquinoxaline to 3.67 μg/kg for difloxacin. The high matrix influence of floral and chestnut honey indicated the need for quantitative analysis using the matrix calibration curve.
