For this purpose, 150 cattle slaughtering was observed and tissue samples were taken from 36 lungs and 21 livers due to the suspicious cyst structure in the macroscopic examinations. They were fixed in 10% buffered formalin solution for histopathology. After routine histopathology process, 5 micron sections were taken from paraffin blocks. Each section was stained according to the procedure with HE, MT and PAS stains, respectively. At the end of the research, hydatid cyst was determined in 26 of 150 cattle (17.33 %). At the organ level; The numbers of hydatid cyst seen in the lung is 22 (14.67%), in the liver is 10 (6.67%) and 6 (4%) both in the lung and liver. In microscopic examinations, protoscolex was also observed in 18.18% of hydatid cysts located in the lung and 20% of cysts located in the liver.
