Since the U.S. Food and Drug Administration approved ractopamine hydrochloride and zilpaterol hydrochloride in animal feeds, usage of those compounds has been a topic of worldwide debate. Ractopamine and zilpaterol are β-adrenergic agonists used as veterinary drugs to increase weight gain in certain animals raised for food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) establishe...

The present study aims at determining the level of contamination jawfish (Chrysichthys nigrodigitatus) by organophosphate residues in hydroelectric dams Faé, Kossou and Taabo. Ninety (90) fish were collected from these three during eight sampling campaigns. Composite samples formed, each for two fish. A total forty-five (45) composite formed. detection pesticide was determined gas chromatograph...

Kresoxim-methyl is nowadays widely used to combat a diversity of common diseases affecting high-value crops. In this article, we report the development and characterization of two novel immunoassays for the analysis of this pioneer strobilurin fungicide, and for the first time, a validation study with food samples was performed. A direct and an indirect competitive immunoassay based on a new an...

A multiresidue gas chromatographic method for the determination of six fungicides (captan, chlorthalonil, folpet, iprodione, procymidone and vinclozolin) and one acaricide (dicofol) in still and fortified wines was developed. Solid-phase microextraction (SPME) was chosen for the extraction of the compounds from the studied matrices and tandem mass spectrometry (MS/MS) detection was used. The ex...

In this study, pesticide residues in sauce manufactured from agricultural products were examined. A simultaneous multiresidue analysis for 260 pesticides samples was performed using liquid chromatography with tandem mass spectrometry (LC-MS/MS). The QuEChERS AOAC 2007.01 (quick, easy, cheap, effective, rugged, and safe) selected as the most suitable protocol routine determination of residues. l...

This study investigated the levels of the antibiotic tetracycline contained in cow milk, goat milk, butterfat, soft cheese and yoghurt samples. High performance liquid chromatography (HPLC) standard methods were used for the detection and quantification of tetracycline in 40 dairy products samples. All the analysed samples contained residues of tetracycline antibiotics. The mean tetracycline re...
