An abattoir survey based study was conducted between November 2011 and March 2012 period, to determine the prevalence and economic significance of hydatidosis in slaughtered ruminants. During the study, Debrezeit Elfora export abattoir were visited twice a week to examine the internal organs (livers, lungs, kidney and hearts) for the presence of hydatid cysts in ruminants and total 203 cattle, 384 sheep and 547 goats were examined for the presence of hydatid cyst. It was found that 42.86% of cattle, 7.03% of sheep and 4.39% of goats were infected with this disease. The cysts in cattle, sheep and goats (P < 0.05) were found mostly in lungs (41.4%, 7.03% and 4.39%) respectively, whereas the liver is second affected organ in all the three species of animals (p< 0.05%). In addition to this, six, two and one kidneys in cattle, sheep and goats respectively and one heart in cattle only were infected with hydatid cyst. In this study, the prevalence of hydatidosis and the number of cysts in ruminants were found different when the cattle, sheep and goats examined were stratified based on their age and body condition.
The prevalence and the number of cysts was high in those animals that has poor body condition and low in those animals having good body condition (P<0.05), but there is no significant difference (P>0.05%) between young and adult ruminants based on age. The economic loss in the value of the income due to carcass weight loss and because of the discarded organs (lung, liver, kidney and heart) annually as a result of hydatidosis was estimated to be 693,987.81 ETB for cattle, 600,465.2 ETB for sheep and 257, 790.19 ETB for goats. The minimum total loss for all infected animals was determined to be 1, 552, 243.2 ETB based on the market prices at Debrezeit in the year 2012.So that application of proper meat inspection was recommended to reduce such situations.
