Introduction
β-Lactam antibiotics, including amoxicillin, ampicillin, and oxacillin, are widely used in animal husbandry for the treatment of bacterial infections. Their extensive use can lead to residues in animal-derived food products such as eggs, posing potential health risks, including allergic reactions and adverse drug responses in consumers. Thus, there is a critical need for effective methods to detect and quantify these antibiotic residues to comply with regulatory standards.
Method Development and Validation
A sensitive HPLC method with UV detection was developed for the simultaneous determination of amoxicillin, ampicillin, and oxacillin residues in eggs. The egg samples underwent extraction with acetonitrile followed by clean-up using C18 solid phase extraction cartridges. The residues were then derivatized with 1,2,4-triazole before analysis. Method validation demonstrated good specificity, linearity, limits of detection and quantification, accuracy, and precision, indicating the method's reliability for detecting these residues at low concentrations.
Finding of Antibiotic Residues in Commercial Eggs
The developed HPLC method was applied to analyze twenty commercial egg samples. The analysis revealed that only one sample contained amoxicillin at a concentration of approximately 7.2 µg/kg. This finding underscores the presence of residues in some commercial products, emphasizing the importance of routine monitoring to ensure food safety.
Importance of Regulatory Compliance
With established maximum residue limits (MRLs) for β-Lactam antibiotics in animal-derived food products, including those set by various regulatory bodies, it is essential to have reliable analytical methods to ensure compliance. This study contributes to that need by providing a validated method capable of detecting low levels of these antibiotics in eggs, thereby helping to protect consumer health and comply with regulatory standards.
Conclusion
The developed ion-pair HPLC method demonstrates adequate sensitivity and specificity for the simultaneous detection of amoxicillin, ampicillin, and oxacillin residues in eggs. Through acetonitrile extraction, C18 cartridge cleanup, and pre-column derivatization followed by HPLC analysis, this method has proven to be effective for monitoring antibiotic residues in food products. The results highlight the necessity of ongoing surveillance to manage and minimize the risks associated with antibiotic residues in the food supply.
