Abstract | ||||
Fifty four random samples (27 milk samples, 12 cream samples, 11 karish (Skim milk) cheese samples and 4 yoghurt samples) were collected from Agriculture Research Station of Kafer El-Sheikh. All collected samples were subjected to extraction and clean up procedure for multi-residue detection of pesticides. The results demonstrated that p,p-DDE was the only and most frequent organochlorine residue contaminates milk and cheese samples. Storage process caused a significant decrease of p,p-DDE residues in cheese samples after 15 days storage. Pasteurization process doesn't cause any decrease in p,p-DDE residue. p.p-DDE and p,p-ODD residues were detected in higher concentrations in case of cream samples compared with milk samples. p,p-DIDD was the only residue that detected in yoghurt samples. None of the milk or milk product samples exceeded the Codex Alimentarius residue limits for DDT complex in milk. | ||||
