Abstract:Fluoroquinolones are a class of synthetic broad-spectrum antimicrobial agents that are widely used in the control of bacterial diseases in farmed animals due to their high efficacy and low costs. However， their excessive use may lead to excessive drug residues in animal-derived products， which may cause food safety risks. The international and domestic maximum limits of fluoroquinolone residues， sample pretreatment techniques， and common detection methods were systematically reviewed， and the development trend of future detection techniques was also prospected， aiming at providing scientific references for the rapid analysis and research of fluoroquinolone residues in animal-derived products.
