Box 395, Nekemte, Ethiopia Abstract: The aim of this study was to identify and determine the major diseases and pathological conditions of organ condemnation and to estimate the magnitude of the direct financial losses attributed to the condemned organs from cattle slaughtered in the Dire Dawa municipal abattoir. A cross-sectional abattoir survey type of study design was employed. Standard postmortem inspection procedures were followed on all cattle approved for slaughter throughout the study period. Postmortem examination was conducted on liver, lungs, heart and kidneys of all cattle slaughtered during the study period. An attempt was also made to estimate the direct financial losses due to condemnation of edible organs during meat inspection. A total of 6441 cattle were slaughtered at the Dire Dawa abattoir in the period of five months from November 2014 to March 2015. Out of examined organs, a total of 1116 (17.3%) organs were condemned. The most condemned organ was liver (73.75%) followed by lungs (14.34%), heart (10.66%) and kidneys (1.25%). The current study revealed that the main causes of organ condemnation were fasciolosis (30.02%) followed by, hydatid cyst (22.67%), hemorrhage and hematoma (16.49%), calcification (15.32%),abscess (4.03%), Cysticercus bovis (3.23%), pneumonia (2.42%) and others resulting in considerable financial loss of about 109,492,727.5 ETB per annum. The findings showed that the rate of organ condemnation at the abattoir is very high which signifies the need for rapid disease control programs to be implemented. Key words: Abattoir Cattle Dire Dawa Financial Loss Organ Condemnation INTRODUCTION Cysticercus bovis and others causes like abscessation and cirrhosis cause a significant financial loss by lowering Ethiopia has the largest livestock population in the productivity of cattle and condemnation of edible Africa with an estimated population of 44,318,877 organs [4]. cattle 23,619,720 sheep, 23,325,113 goats, 6 million Several studies have been conducted through equines, 2.3 million camels and 43 million poultry [1]. abattoir survey to determine economic loss resulting from Ethiopia s great livestock potential is not properly organ condemnation in many abattoirs of Ethiopia [5]. exploited due to different factors such as traditional However; most of the studies were focusing only on management system, limited genetic potential, lack of specific diseases. Furthermore, financial loss due to appropriate disease control policy and lack of appropriate various diseases/causes was estimated in some abattoirs veterinary services [2]. of the country [4]. Postmortem inspection is the center The significant financial losses incurred each year around which meat hygiene revolves since it provides in the different abattoirs in Ethiopia are due to inferior information indispensable for the scientific evolution of weight gain and condemnation of edible organs at clinical signs and pathological processes that affect the slaughter. This production loss in the livestock industry wholesomeness of meat [6]. is estimated at more than 900 million USD annually [3].

carcass or an organ should be carried out as soon as Study Animals: The study animals were cattle brought to possible after completion of dressing. The main purpose the abattoir for slaughter from different districts in and of post mortem examination is to detect and eliminate around Dire Dawa town and it included both sexes abnormalities, including contamination, thus ensuring that weather they are from intensive or extensive farming only meat fit for human consumption is passed for food system. [6]. Meat inspection is commonly perceived as the Study Design: A cross-sectional study design was sanitary and safety control of slaughter animals and meat. employed to identify the major cause of organ The purpose of meat inspection is to protect public health condemnation in Dire Dawa town municipality abattoir and to provide safe and wholesome meat for human and to evaluate the direct financial losses due to organ consumption. The responsibility for achieving this condemnation. The organs of cattle slaughtered in the objective lies primarily with the relevant public health abattoir during the study period were investigated and the authorities who are represented by veterinarians and meat causes for condemnation of the organs were recorded. inspectors at the abattoir stage [7]. In Ethiopia many studies have been carried out to Sample Collection: For this study all cattle slaughtered identify the major causes of organ condemnation during during the study period were considered. Accordingly postmortem inspection and to determine the financial each cattle slaughtered at abattoir were subjected to both losses due to organ condemnation. However, there is no ante mortem and post mortem inspection according to the enough information on the major causes of organ meat inspection standard. After that the organs condemnation and its financial importance at Dire Dawa condemned were investigated and the major causes of municipal abattoir. Therefore, the objectives of this condemnation were identified [6]. Organs and carcasses research paper were to identify the major causes of organ were collected and examined thoroughly using visual condemnation and to estimate the direct financial losses inspection, palpation and systematic incision of each from organ in cattle slaughtered at Dire Dawa municipal organ and carcass for the presence of abnormalities. abattoir Pathological lesions were differentiated and judged according to the guideline of meat inspection for MATERIALS AND METHODS developing countries [9]. Study Area: The current study was conducted from Financial Loss Assessment: To assess the financial November 2014 to March 2015 at Dire Dawa losses of organ condemned only direct financial losses Municipal abattoir. It is located in Dire Dawa were considered. To establish the price per unit organ the Administration Council (DDAC), situated in the average organ price was determined and this price index eastern part of Ethiopia at about 515km from capital, was used to calculate the loss [10]. The analysis was Addis Ababa.

Data Management and Analysis: The data collected from the abattoir was recorded in the format developed for this purpose and later on entered into the Microsoft excel 2007 program and analyzed using STATA 11.0 software. Tables were used to present results of pertinent findings. RESULTS Post Mortem Examination: A total of 6441 cattle were slaughtered at Dire Dawa municipal abattoir in the period of five months from November 2014 to March 2015. Out of examined organs, a total of 1116 (17.3%) organs were condemned. The most condemned organ was liver (73.75%) followed by lung (14.34%), heart (10.66%) and kidney (1.25%) (Table 1). As indicated in the table 2 below, the most common disease encountered was fasciolosis (30.02%) followed by, hydatid cyst (22.67%), hemorrhage and hematoma (16.49%), calcification (15.32%),abscess (4.03%), Cysticercus bovis (3.23%), pneumonia (2.42%) and others Liver was the most often condemned organ and parasitic pathological conditions were the major cause of condemnation. Fasciolosis 335 (40.07%) was found to be the main cause of liver condemnation followed by hydatid cyst 206 (25.03%), calcification 171 (20.78%) and Cysticercus bovis 26 (3.16%). The major causes of lung condemnation were hemorrhage and hematoma 94 (58.75%), pneumonia 27 (16.88%), hydatid cyst 20 (12.50%) and emphysema 9 (5.63%). The major causes of heart condemnation were hemorrhage and hematoma 72 (60.5%), hydatid cyst 27 (22.69%) and C. bovis 10 (8.4%). Abscess 6 (42.86%), atrophy 4 (28.57%) and hydronephrosis 3 (21.43%) were the major causes of kidney (Table 3). Financial Loss Assessment: The total financial loss due to organ condemnation in cattle slaughtered at Dire Dawa Municipal abattoir was assessed from the annual organ condemnation cost (Direct loss). The direct financial loss was resulted from organs condemnation as the result of major pathological findings. Generally all infected organs were unfit for human consumption. Out of 6441 slaughtered cattle 1116 organs were condemned. In Dire Dawa Manucipal abattoir, the average annual cattle slaughter rate was estimated to be 13975 heads while by taking the average market price of each lung, liver, heart and kidney as 10, 100, 25 and 40 Ethiopian Birr respectively, the financial loss due to organ condemnations at Dire Dawa Manucipal abattoir was estimated (Table 4).

The present study revealed that fascioliasis, hydatid cyst, calcification, Cysticercus bovis, pneumonia, emphysema, pericarditis, hemorrhage and hematoma, atrophy, nephritis, hydronephrosis, cirrhosis, hepatitis, and abscessation were the major causes of organs condemnation in cattle slaughtered at Dire Dawa Municipal abattoir. From a total of 6441 head of cattle slaughtered, 1116 (17.3%) organs of cattle were condemned because of different diseases and pathological findings. 121

Out of the total examined organs 73.75% liver, 14.34% 42.86% and 28.57% respectively. Hydronephritis (21.43%) lungs, 1.25% kidneys and 10.66 % hearts were condemned and nephritis (7.14%) were also other causes of due to various causes. The rate of liver condemnation in condemnation. According to the report by Fasil [16] the this study was much higher than the report of Denbarga main cause of kidney rejection were nephritis, et al.

These could be due to poor health Wolaita Soddo Municipal abattoir by Fufa and Debele care, extensive cattle husbandry and grazing system. [13] was estimated to be 24,340 ETB (24323.49 USD). Calcification, hydatid cyst, C. bovis, abscess, These may be due to the variation in the cost of the each hepatization, hemorrhage and hematoma and cirrhosis organ in different study areas and numbers of organs were also other causes of liver condemnation. condemned during the study period. The rate of lung condemned due to hemorrhage, emphysema, hydatid cyst, pneumonia and abscessation CONCLUSION was 58.75%, 16.88%, 12.50%, 5.63 and 5.00% respectively. In this study hemorrhage was the main cause of lung In the present study fascioliasis, hydatid cyst, condemnation.
