Use of Temperature-controlled Ionic Liquid-assisted Dispersive Liquid-Liquid Microextraction Method for the Detection of Amoxicillin, Cloxacillin and Erythromycin Residues in Cow Milk using High Performance Liquid Chromatography
Background and Objectives: Different types of antibiotics are used indiscriminately in animal husbandry for the growth and treatment of livestock, which cause accumulation of antibiotic residues in livestock products such as milk. Long-term consumption of milk contaminated with antibiotic residues above the permissible limits is harmful to human health, causing antibiotic resistance problems. T...
متن کاملDetermination of Aflatoxins B1 and B2 in Powdered Milk Using Modified Liquid Chromatography Method
Background & Aims: In this study, using a liquid-liquid microextraction method for pre-concentration trace amounts of aflatoxins, the amount of Aflatoxins B1 and B2 in powdered milk was determined. Determination of aflatoxins was done by using high-performance liquid chromatography coupled with fluorescent detector. Method: Samples were extracted by immunoaffinity column (IAC) clean-up, and the...

متن کاملDetection of Oxytetracycline Residue in Infant Formula by High-Performance Liquid Chromatography (HPLC)
Determination of drug residues in food is of great importance due to their toxicity. Long-term exposure with low level of drug residues could be important, especially in children. Based on document study, oxytetracycline (OTC) is a prophylaxis and treatment agent for great number of diseases and possesses a broad spectrum activity against many pathogenic organisms and can be toxic or cause alle...
متن کاملACROSS-SECTIONAL STUDY ON OXYTETRACYCLINE AND TETRACYCLINE RESIDUES IN PASTEURIZED MILK SUPPLIED IN TEHRAN BY AN HPLC METHOD
Tetracyclines (TCs) are broad-spectrum antibiotics that are used widely in veterinary medicine. The present study was carried out to trace the residues of oxytetracycline (OTC) and tetracycline (TC) in pasteurized milk that is marketed in Tehran with the use of a High Performance Liquid Chromatography (HPLC). Ninety milk samples were collected during five sequential days from the products of si...
