Major Parasitic Causes of Organs Condemnation and Direct Economic Loss Attributed to the Condemned Organs in Sheep and Goats brought from Somali, Afar and Borena Areas and Slaughtered at ELFORA Export Abattoir
Biomedical Journal of Scientific & Technical Research
Each year a large loss from slaughtered animals results due to condemnation of edible organs. Therefore, cross-sectional study was conducted from November 2017 to April 2018 at Bishoftu ELFORA export abattoir to determine the major parasitic cause of organs condemnation in small ruminants brought from Somali, Afar and Borena areas, and to estimate the magnitude of direct economic loss attributed to the condemned organs. 768 small ruminants comprising equal number of sheep and goats were simple
... goats were simple randomly selected. Ante-mortem inspection was carried out on arrival in the lairage; temporal identification numbers were given for selected individual animals and abnormalities encountered were recorded. Then after, post-mortem examination was performed in each organ of individual animals along their identification number to detect gross abnormalities and aesthetic reasons that rendered each organ to be rejected from local market. During this study period out of the total 384 both sheep and goat organs examined, 179(23.3%)livers, 61(7.9%) lungs,4 (0.5%) hearts ,2(0.3%) kidneys and 20(2.6%) of both liver and lung were rejected due to parasitic causes: The major causes of condemnation were Stelisia hepatica (11.3%) and Cysticercus tenuicollis (6.3%) for liver; lung worm (5.7%) and Hydated cyst (2.2%) for lungs; Cysticercus ovis (0.5%) for heart and Hydated cyst (0.3% for kidney and 2.6% for both liver and lung). Rate of condemnations due to parasitic causes was higher in the liver (23.3%) than in the lungs (7.9%) and parasitic causes particularly Stelisia hepatica, Cysticercus tenuicollis and Hydated cyst were the major causes of economic loss through condemnation of affected organs. The overall prevalence of major parasitic cause of organ condemnation in this study was found to be 34.6% and the total annual economic loss incurred due to this condemnation at the study abattoir was estimated to be 45,379.00 ETB. Therefore, creation of awareness on animal attendants and/or small ruminant owners and abattoir workers about the effect of parasites and safe disposal of condemned organs must be made.
