Resumen:
Coccidiostats are pharmaceutical compounds used for the treatment and prevention of coccidiosis, as well as for improving feed conversion in the treated animals. Their use as a feed additive is customary among animal breeders since, by controlling and minimizing the spread of the disease, they can maximize the economic profit of their activity. In the case of coccidiostats, their use must be suspended before animal slaughtering, providing enough time for their metabolization and elimination from the organism. Unfortunately, this recommended practice is not always fulfilled by the farmers or, even if it is, significant amounts of the drug can still be found in some animal products. A method for the simultaneous determination of four commonly used coccidiostats (toltrazuril (TOL), decoquinate (DEC), ethopabate (ETH) and robenidine (ROB)) in chicken liver was developed, comprising a multi-residue extraction technique, namely QuEChERS (quick, easy, cheap, effective, rugged and safe), and a liquid chromatography - ultra violet - fluorescence (HPLC-UV/FL) analysis
