Antibiotics Residues in Honey: Validation Procedure Honey Analytical Methods Validation
نویسندگان
چکیده
An uncontrolled used of antibiotics and sulphonamides is responsible for the presence of residues in beehive products and contributes to the problem of food safety. The optimisation of analytical methods for the detection of residues of antibacterial drugs (sulphonamides, SPs; tylosin, TL; streptomycin, ST) in honey was pursued and the methods applied to routine samples. ST was investigated by liquid chromatographic technique with a post column reaction and fluorimetric detection. SPs were quantified by HPLC equipped with fluorimetric detector and C8 column after a precolumn derivatisation by fluorescamine. The presence of TL residues in honey was confirmed by liquid chromatography – tandem mass spectrometric detection. Chromatographic separation of TL was performed on a C18 column. The validation parameters obtained with these methods were: 88%, 101% and 95-102% for recovery and 10 ng/g, 5 ng/g and 1 ng/g as quantification limits for ST, TL and SPs, respectively.

Several Belgian beekeepers were asked to shut down their hives due to withering of the hive. The cause of the withering was unknown. A multi-factoral study was initiated, which included a multi-class pesticide residue study from honey, to determine if pesticides were the cause of the decline. The extensive distribution of pesticides causes bees that have been fed on contaminated blossoms to tra...
