In order to identify the status of infection with sheep Fasciola hepatica in Lintao County and its surrounding regions in Gansu Province，18 373 slaughtered sheep were examined by local post mortem of helminths during 2018 to 2020，it was found that the average infection rate and intensity were 43.1% and 39.3 worms，respectively. The sheep with 1 to 50 worms accounted for 90.6% of the infected ones，those with 51 to 100 worms for 9.3%，and those with more than 101 worms for 0.1%；in 2018，the infection rate was highest（53.3%）and the average infection intensity was maximum（46.5 worms），which was statistically different（P＜0.05）with the information in other years；In 2019 and 2020，the infection rate remained above 40%，and the average infection intensity was above 42 worms. The average infection rate and infection intensity were maximum（51.2% and 43.0 worms）in Weiyuan County，and minimum（8.8% and 13 worms）in Anding District；the range of infection was largest in Lintao County，which was 8 to 138 worms. It was concluded that sheep Fasciola hepatica was widely distributed in the region，with a high infection rate，which was increasingly serious year by year with the characteristics of a certain regional distribution. All of the above should be highly concerned by the authorities for animal disease control who should take a series of measures including strengthening publicity of the harmfulness of Fasciola hepatica and training related to the technology of prevention and control，improving the awareness of the public，and guiding farmers to graze reasonably and de-worm regularly，so as to reduce any possible harm of Fasciola hepatica to the development of local sheep industry. A reference was provided by the study for future control of Fasciola hepatica in the above 5 counties/districts.
