Monitoring of some Organochlorines and Organophosphorus residues in imported and locally raised chicken and bovine muscles in Egypt.

Abstract

Organochlorine and Organophosphorus Pesticides are found in many parts of the environment in small concentrations, but they have cumulative characteristics thus become a threat to human health and life. This study is focused on detection and determination of some of these pesticides in the muscles of chicken and bovine in the Egyptian market whether it was imported or raised in Egypt. Samples of locally raised chicken and bovine were collected from 5 areas: Al Giza, El Saf, El Ayat, El Hawamdeya, El Badrasheen (5 samples of chicken and 5 samples of meat from each area). Imported chicken were collected from the local market, all of the samples were imported from Brazil (25 samples), meanwhile, bovine samples were imported from: Netherlands, India, Sudan and Brazil (5 samples from each country except Brazil, 10 samples). Samples were prepared, then extraction, partitioning and clean up processes has been conducted and the aliquots were analyzed by Gas Chromatography (GC) using ECD (electron capture detector) and FPD (Flame Photometric Detector). The study showed that a lot of samples were contaminated with organochlorine pesticides while fewer samples were contaminated with organophosphorus pesticides.
