Abstract

This study aimed to address a knowledge gap in the presence of antimicrobial residues in fish aquaculture products. Screening of food products from animal origin for the presence of antimicrobial residues has become a necessity due to the widespread use of these drugs as well as the development of resistant bacterial pathogens which has become a global issue. Tetracycline, ceftiofur, fiorfenicol, quinolone, streptomycin, and tylosin were screened in lateral muscle samples of Nile tilapia (Oreochromis niloticus) obtained in the coastal barangays of Los Banos, Laguna, Philippines. Using biochip immunoassay, the following results were obtained: tetracycline (100%), ceftiofur (100%), quinolone (83%), and fiorfenicol (9%). Streptomycin and tylosin were not detected in the samples. A minimum of two to a maximum of four classes of antibacterial were found in each sample. Although the residues did not exceed the established maximum residue limit (MRL), these still pose a health risk to consumers in view of widespread concern about antimicrobial resistance.
