Detection of multiple presence of antibiotic residues in slaughtered sheep at Duhok abattoir, Iraq

Abstract EN

The aim of this study is to investigate the presence and/or multi-presence of tetracycline, penicillin G, streptomycin, and gentamicin residues in slaughtered sheep carcasses at Duhok abattoir using ELISA technique.

Eighty-eight samples were collected from different sites of twenty-two sheep carcasses.

These samples included Longissimus dorsi, diaphragmatic muscles, liver and kidney.

The samples were prepared, homogenized, extracted and assayed according to ELISA kit instructions.

The results revealed that all 22 carcasses were contained at least one type of tested antibiotics.

Multiple antibiotic residues were found in 17(77.27%) of examined carcasses.

The study indicated that local ovine meat sold in Duhok province generally contained residues of antibiotics.

Animals slaughtered might have been treated with veterinary drugs and the proper withdrawal period was not respected before slaughtering.
