However, the antibiotic residues in meat are a serious public health concern due to their harmful effects on consumer health. Besides this problem, there is limited information on the level of the antibiotic residues, including tetracycline residues. Therefore, this study was aimed to determine the tetracycline residues in the kidney and muscle samples of beef cattle in Harar town and Dire Dawa city. Methods: A study was conducted on 500 randomly selected carcass (250 kidney and 250 muscle samples) slaughtered at Dire Dawa and Harar municipal slaughterhouses between December 2018 and December 2019. The samples were collected aseptically and screened for tetracycline residues by thin layer chromatography. Then, presumptive positive samples were analyzed using high-performance liquid chromatography to get a quantitative outcome. Descriptive statistics were used to de...

Penicillin is commonly used veterinary drug to treat mastitis in dairy cattle. However, abundant use of it may be associated with the presence of its residues in milk at unsafe concentrations that can adversely affect public health. Therefore the present study was undertaken to detect penicillin residues in milk from six private dairy farms at Kombolcha North East Ethiopia during the time period between December 2015 and March 2016. A total of 100 milk samples were collected from healthy lactating cows of six dairy farms and were screened for Penicillin residues by using Delvotest SP NT. Moreover a questionnaire survey was carried out by personal interviews with all of the dairy farm owners from whom milk samples were taken, to assess their awareness about dairy farm management practices and antibiotic residues. Penicillin residues (at ...

The animals were included in the study using systematic random sampling. The gross lesions included firm and enlarged livers with tense capsule, haemorrhagic spots, multi focal nodules and enlarged hepatic lymph nodes. The bile ducts were thickened and distended with adult fluke especially in chronic cases. Frequently observed histologic lesions were, hepatic portal fibrosis with large amount of fibrin in the portal area, hepatocytes degeneration, fatty changes and periportal necrosis. Fibrous connective tissue of various amount with fibroblasts and infiltration of mononuclear cells, in particular lymphocytes were common lesions in tracts migrated by parasites. Biliary cirrhosis with epithelial hyperplasia were also observed in cattle and sheep. Eosinophilic hepatitis, talengechtasis and hepatocytes degeneration and necrosis were evident in the parenchyma. Chronic lesions were less prominent in goats‘ and even no cirrhotic case examined in goat. Cytological examination showed large number of lymphocytes and few plasma cells and eosinophils. The findings of the present study indicated that gross, histopathological and cytological examination supports one another in characterization of liver lesions hence could be used together in diagnosis of ruminant fasciolosis. However, additional diagnostic tests would be added for better confirmation.

A total of 1163 serum samples were collected from 251 sheep and 912 goats. Competitive Enzyme Linked Immunosorbent Assay (c-ELISA) was used to detect the presence of antibodies in the sera of animals as
