    This research was performed to determine the effect of boiling, grilling and cold storage processes on florfenicol residues in muscle tissues of sturgeons. A total of 16 sturgeons, 10 of which have received single dosage of florfenicol at 10 mg kg(-1) bw day(-1) level and remaining 6 have not received any florfenicol were used in this study. The analyses were performed by HPLC. The mean recovery rate and repeatability pooled-RSD r% of analytical method for florfenicol analysis of sturgeon muscle were determined as 83.4 +/- 1.07% and 17% respectively. The florfenicol levels were 40.30 +/- 8.23% in the muscle tissue of boiled fish, 57.80 +/- 7.46% in the boiling juice, 101.10 +/- 4.01% in the grilled tissue and 78.01 +/- 15.40% and 62.36 +/- 11.60% in the muscle tissues of fishes, which were stored at -20 degrees C, on the 20th and 50th days respectively. The initial florfenicol level in the fish muscle was significantly reduced (P<0.05) by boiling and cold storage processes. A decrease occurred in florfenicol level in boiling process due to the transfer from muscle tissue to boiling juice, and there was no decrease in the florfenicol level as a result of grilling.
