The present study was carried out a market- basket survey with the aim of determination of the concentration levels of some toxic chemical residues in raw imported meat sold in Assiut city and to assess the potential health risk associated with exposure to these residues from meat consumption. In this work, we tried to compare the situation of Organochlorine (OCs), Organophosphorous (Ops), herbicides and polychlorinated biphenyles (PCBs) residues levels in Brazilian and Indian imported meat in Egypt. The study investigated a total of 100 raw meat samples were randomly collected and divided into two groups: 50 samples from imported Brazilian meat and other 50 samples from imported Indian meat. Samples were collected along the year from January to December 2013 from units available in retail stores in Assiut city. There was no repetition of batches. The average chemical compound residue concentrations ± SE were calculated where n = 25 pooled samples with two samples each. The meat samples were subjected to multi-residues determination of some different types of pesticides and PCBs residues in meat by GPC and PSA solid phase extraction cleanup. It was followed by gas chromatography–mass spectrometry GC/MS determination and analysis. All samples were treated and analyzed using GC/MS–SIM mode (selected ion monitoring) not scan mode. The residues of different compounds were compared with maximum residues limit (MRLs) of different international regulations but basically with the European (EU) MRLs as a basic choice of comparison for the following reasons: first, the European Commission fixes MRLs for the vast majority of chemical residues in meat. Second, EU has the lowest MRLs among the other regulation and sometimes there is a gap between MRLs of EU and other regulations.
