Dioxin residues in beef carcasses in Beni-Suef City, Egypt

Abstract EN

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 the average 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).
