Abstract The study was carried out during a 3-year period. Of 9501 cattle examined, 736 (7.7\%) were infected with cysticerci of Taenia saginata. The endemic foci were identified and prevalence was significantly higher (P < 0.005) in animals from Noorabad Mammasani (10.7\%), Kenareh (10.0\%) and Shiraz area (8.5\%) than elsewhere. The prevalence was significantly higher (P < 0.005) during spring and autumn seasons. There was no variation in the infection rate in animals of different age groups, suggesting that immunity was acquired to super-infection. The most common sites were muscle of the shoulder (26.3\%) and masseter (23.7\%), tongue (24.9\%) and heart (23.4\%). Pharynx, oesophagus and diaphragm showed 0.9, 0.5 and 0.4\% infection, respectively. The metacestode caused extensive damage resulting in infiltrative, degenerative changes, haemorrhages, necrosis and exudation mainly in the vicinity of cysts. The infection was the cause of condemnation of 34.6\% of infected carcases. The rejected carcases and infected organs were valued at 100.1 million Rials over the 3-year period.
