A cross-sectional study was conducted during four seasons from April 2016 to Mach 2017 to assess the status of cystic hydatidosis in the slaughtered camels at the Semnan municipal slaughterhouse, in Semnan province.
Hydatid cyst count and characterization were conducted based on routine meat inspection. Out of the total of 254 camels (97 females and 157 males divided in three age groups as <5, 5–10, and >10 years old) examined visually and manually by palpation and incision, 51(20/07%) were found harboring hydatid cysts in lung, liver and spleen.
A significantly higher infection was detected in older camels (P<0.05) than younger ones. Of the total 51 infected, 25 (9.81 %) had hydatid cysts only in the lung, 11 (4.33 %) in the liver, 16 (6.29 %) in both the liver and lungs, and 2 (0.78 %) in lung, liver and spleen. Out of the 70 viscera harboring hydatid cysts, the highest (58.57%) was the lungs followed by the liver (38.57%), and the spleen (2.85%). In addition, out of the total 405 cysts collected, 16.79% were calcified cysts. The rate of cyst calcification was higher in the liver than in the lung. The results showed that hydatidosis is one of the major parasitic diseases in the study area. In light of the result obtained and the current situation in Municipal abattoirs in Semnan province, serious attention for its prevention and control is warranted.
