In Iran, the disease is common in domestic animals, and human infection has been found from various regions. In this study, the frequency of parasitic diseases consisting of hydatidosis, fasciolosis, and dicrocoeliasis was investigated in sheep, goats, and cattle that slaughtered in slaughterhouses of West Azerbaijan province (northwestern of Iran) between 2014- 2019. Touch and incision methods were used to investigate hydatidosis and liver parasites. According to the results, the prevalence in 2018-2019 in sheep, goats, and cattle was lower than in other years.
