Major Disease That Cause Lung, Liver and Carcass Condemnation and Its Financial Loss at Modjo Modern Export Abattoir

Abstract

A cross sectional study was conducted from November 2016 to April 2017 at Modjo Modern Export Abattoir. A total of 842 apparently health sheep and goats slaughtered at the abattoir were thoroughly examined during post mortem inspection to identify the major causes of liver, lung and carcass condemnation. An attempt was also done to estimate the associated direct financial loss of the abattoir due to rejection of liver and carcass from international markets and lungs from local markets. Post mortem inspection showed that 467 (55.5%) livers 341 (40.5%) lungs and 95 (11.3%) carcasses in the category of both age and species were condemned due to various gross pathological lesions and aesthetical values. The major causes of condemnation were Cysticercus tenuicollis (14.01%), Stelesia hepatica (11.87) and fasciolosis (5.9%) for liver, pneumonia (20.3%), adhesion (5.34%) and emphysema (4.5%) for lungs. Bruising 26 (3.08%), adhesion 25 (2.96%), jaundice 23 (2.73%) and pox like lesions 21 (2.49) were the major causes contributed to the carcass condemnation. The annual financial loss of the abattoir was estimated to be 1,565,883.2 USD. The result of this study revealed that the rate of carcass and specially organ condemnation in the abattoir was high and needs immediate preventive and control measures to be implemented.
