Prevalence and associated risk factors of hydatidosis in cattle slaughtered at Wolaita Sodo municipality abattoir

Abstract

AbstractBackgroundHydatidosis, caused by the larval stage of the tapeworm Echinococcus granulosus, affect cattle by forming hydatid cyst in thier lungs, livers and pose great financial loss in animal production and country's economy by both direct and indirect effect. Despite its great economic and health importance, there is an absence of current information on cystic echinococcosis in cattle slaughtered at Wolaita Sodo municipality abattoir in Ethiopia.ObjectivesCurrent investigation determines the prevalence, organ distribution and fertility of hydatid cysts in cattle slaughtered at the Wolaita Sodo municipality abattoir in Ethiopia.MethodsA cross‐sectional study was conducted from February, 2023, to October, 2023, at Wolaita Sodo municipality abattoir in southern Ethiopia, through regular meat examinations and cyst characterisation to determine the prevalence, organ distribution and fertility of hydatid cysts.ResultsThe overall prevalence of hydatidosis recorede in current study was 17.9% (69/384) and has shown a statistically significant association (p < 0.05) with the body condition of cattle. However, there was no statistically significant association (p > 0.05) between the prevalence of hydatidosis and other risk factors such as sex, breed, production system and origin of animals. This study showed that the lungs and liver were the most affected organs in cattle, followed by the spleen and kidneys. On cyst characterisation, the majority of hydatid cysts were found sterile (55.4%) followed by fertile (38.8%) and calcified (8.7%) cysts. Out of 125 fertile hydatid cysts tested for survival, 18.8% (58/321) were viable and 20% (67/321) were nonviable.ConclusionThe finding of this study shows that cystic echinococcus was important health threat of the cattle and widespread in the internal organs of affected cattle causing significant economic loss by condemning edible organs that are not suitable for human consumption. Therefore, urgent and integreted preventive action is needed to disrupt the life cycle of cystic echinococcosis to tackle subsequent financial loss and risk of zoonosis to humans in the study area.
