Abstract A high throughput quantification multi-residues method for the simultaneous detection of 39 pesticides and veterinary drugs in aquaculture products were developed by using Ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) with modified QuEChERS (quick、easy、cheap、effective、rugged、safe). In order balance recovery efficiency, several parameters optimized, including extracting, clarification, purification. Chromatographic conditions optimized given run time ＜ 13 min. Six representative matrices (muscle tissues yellow croaker, pomfret, shrimp, white shell, flower razor clam) show applicability all target analytes showed recoveries (60.3%~119.0%) acceptable precision (4.3%~20.8%). Furthermore, limits (LODs) (LOQs) range 1.0 ~ 5.0 µg/kg 3.0 10.0 µg/kg, respectively, that providing a practical safety internal risk controlling aquaculture.

Canthaxanthin and β-apo-8'-carotenoid ethyl ester are widely used as feed additives in poultry for enhancing the color of products. The excessive intake two colorants can cause health damage. According to European Food Safety Authority (EFSA), acceptable daily (ADI) canthaxanthin 0.03 mg/kg·bw 0.015 mg/kg·bw, respectively. Ultra-high-performance liquid chromatography-diode array detector (UPLC-DAD) was determine chicken eggs meat. A PRiME HLB solid-phase extraction cartridge extract clean-up sample. BEH C18 column separation column, with water containing 0.1% formic acid acetonitrile mobile phase. limit detection (LOD) 0.05 mg/kg, quantification (LOQ) 0.1 mg/kg. recoveries were between 90% 104%. meat evaluated based on data, food consumption data weight population. mean estimated (EDI) values through 1.09 µg/(kg·bw·d) 0.013 µg/(kg·bw·d), EDI value 0.44 µg/(kg·bw·d). results showed that main contributor colorants. hazard quotients (HQ) within a safe range.

Quinolone antibiotics are widely utilized in aquaculture, but little is known about the health effects of their residues. This study used UPLC-MS/MS to analyze distribution 11 quinolone cultured fish sold a coastal city southeast China - Fujian Province and assess risks. The found 35.77% 260 samples detected quinolones, with three exceeding MRL one containing banned drug ofloxacin. Of quinolones tested, were fish, enrofloxacin at up 246.0 μg kg
