Echinococcus granulosus is the causative parasite of hydatid disease in humans and represents a significant public health problem within endemic foci in all major continents of the world. This report gives a detailed set of instructions whereby four trained individuals can examine 15–20 dogs per hour for the presence of this organism. The procedure permits the baseline determination of the prevalence of this parasite within any specific population of dogs and also allows the periodic examination of the same animals to determine if recommended preventive and control measures for hydatid disease are being followed by sheep and dog owners in any region where the parasite is known to occur.
