Determination and confirmation of chloramphenicol residues in swine muscle and liver

Average high-performance liquid chromatography (HPLC) recoveries of chloramphenicol (CAP) in swine muscle and liver ranged from 91.3 to 94.2% and 93.1 to 103.7%, respectively, with coefficients of variation ranging from 1.4 to 4.3% and 1.1 to 11.2% for each tissue sample. The method described was repeatable and reproducible in swine muscle and liver, with a limit of quantification of 15 ng/mL and a limit of detection estimated at 5 ng/mL. The limit of identification of CAP was 25 ng/mL, 5ng/mL, and 20 ng/mL for HPLC/PDA, GC/MS selected ion monitoring (SIM), and LC/MS analysis, respectively. Le chloramphenicol est utilise comme antibiotique a large spectre en medecine veterinaire, mais presente un risque pour le consommateur de viande selon la FAO. Le foie est l'organe ou les concentrations sont les plus elevees apres la diffusion rapide du produit. Une technique HPLC avec une limite de detection de 5ng/ml et une limite de quantification de 15ng/ml, fiable et reproductible est presentee dans cet article.
