Abstract

The aim of the present study was to investigate the presence of antibiotic residues in rainbow trout fishes through a Four-Plate test. In this study, 240 rainbow trout samples (weight = 800 g - 1700 g) were purchased from the main local markets of Kermanshah city during four seasons, including summer, spring, autumn, and winter 2020-2021. The results of this study showed that based on the inhibition zone diameter at pH 6, 16 samples were collected from Lorestan province (20%), 13 samples were collected from Kermanshah province (16.25%), and 6 samples were collected from Kurdistan province (7.5%) had antibiotic residues, i.e. the inhibition zone diameter was more than 2 mm. Accordingly, the main antibiotics consumed in rainbow trout farming in Kermanshah, Lorestan, and Kurdistan provinces were probably the fluoroquinolone family. The results of the present study indicate that the rainbow trout samples collected from the main local markets of Kermanshah city had no remarkably antibiotic residues.
