On July 5, 2016, the unexplained disease and mortality occurred on a black goat farm （about 200 goats）, the morbidity and mortality rates were approximately 50% and 20%, respectively. Necropsy showed that there were visible severe ascites and liver damage in abdominal cavity of one dead goat, but no obvious lesions in other organs. Interestingly, there were plenty of Fasciola hepatica in liver and gall bladder. According to the incidence and pathological changes, the incidence and cause of death for goats were determined as the infection of Fasciola hepatica. Comprehensive prevention and control measures （including drug treatment and limit goat movement） were taken, after a week, follow-up study showed that there were no new cases and deaths in goat herds except for some previous serious infections and deaths of goats.
