Residual problems closely concerning human health arise in food producing animals treated with veterinary drugs. The aim of this study was to investigate the residues of benzimidazole anthelmintic drugs (thiabendazole, albendazole, oxfendazole, triclabendazole, fenbendazole and mebendazole) in ruminant kidney and liver tissues, which are being widely utilized against internal parasites in Turkish animal husbandry. A total of 100 samples of sheep and cattle liver and kidney tissues (25 samples each) were analysed by high-performance liquid chromatography (HPLC). No residues of benzimidazole anthelmintics were found in the samples. This result was found positive for public health.
