DETERMINATION OF ENROFLOXACIN RESIDUE IN CHICKEN EGGS USING LIQUID CHROMATOGRAPHY – MASS SPECTROMETRY METHOD

The number of poultry farms in Kosovo is constantly increasing and the need to prevent infectious bacterial infections in poultry has led to the use of antibacterial preparations, which in addition to the beneficial effects of combating these diseases, also poses risk to public health. The purpose of this study was to confirm the presence or absence of enrofloxacin residues in 8 egg samples, after analyzing 180 eggs samples collected at commercial farms in Kosovo with the Elisa Test. The confirmation method used was the Liquid Chromatography Mass Spectrometry. 2 of 8 samples resulted with presence of enrofloxacin residues. The findings suggest that illegal use of enrofloxacine in chicken farms is present and highlight the fact that chicken farmers were using antibiotics as a promoter of egg production and body weight and to reduce the incidence of infectious diseases. Both the tests are performed at the Kosovo Food and Veterinary Laboratory. The testing was performed according to the Commission Decision 2002/657/EC
