A total of 100 fat samples were collected from slaughtered cattle at Beni-Suef slaughter house. Animals were randomly selected from the slaughter line. The age of the slaughtered cattle was normally less than three years (18-30 months). Samples were separately packed in plastic bags, identified and stored at -18°C until analysis. The analysis was conducted at Max Rubbner Institute, Kulmbach, Germany for PCDDs, PCDFs and dl-PCBs. The average concentration sum for PCDD calculated as upper bound pg WHO-TEQ/g was 1.71 pg WHO-TEQ/g fat. While theaverage concentration sum for PCDFs was 4.93 pg WHO-TEQ/g fat. The average concentration sum of dl PCBs including non-ortho and mono-ortho PCBs was 5.091 pg WHO-TEQ/g fat. The total TEQ value for PCDD/Fs and dl-PCBs was 11.74 pg WHO-TEQ/g fat. The residual levels of PCDD/Fs and dl-PCBs in the examined beef fat samples were higher than the proposed maximum permitted levels set by the European Commission (2006).
