Determination of Enrofloxacin Residue in Chicken Eggs Using Liquid Chromatography – Mass Spectrometry Method

Abstract

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

Study on immobilisation process on lateral flow assay test strip for detection of Enrofloxacin antibiotic by inkjet printing

“…Currently, the demand for a sensitive, rapid, cost-effective, and user-friendly detection method for Enrofloxacin is emerging. Various screening methods have been documented for Enrofloxacin detection, encompassing techniques such as high-performance liquid chromatography (HPLC) [20,21], surface plasmon resonance (SPR) [22,23] and liquid chromatography-mass spectrometry (LC-MS) [24,25]. Despite their high accuracy, the aforementioned techniques are characterised by time-intensive and costly protocols, necessitating skilled personnel, rendering them unsuitable for swift on-site Enrofloxacin testing.…”
