Citation: Ahmed AM, Elshraway NT, Youssef AI (2016) Survey on Sarcocystis in bovine carcasses slaughtered at the municipal abattoir of El-Kharga, Egypt, Veterinary World, 9(12): 1461-1465.

Aim: The main objectives of this study were to determine the incidence of Sarcocystis sp. infection in cattle and buffalo carcasses slaughtered at El-Kharga abattoir, New Valley Governorate, Egypt.

Materials and Methods: The slaughtered animals were daily inspected for Sarcocystis macrocysts through a year (2015). Macroscopic Sarcocystis was detected from a total of 2120 cattle and buffalo carcasses. In addition, 100 meat samples were collected from female cattle and buffalo (50 each) and were examined microscopically for sarcocystosis.

Results: The overall incidence of Sarcocystis macrocyst among bovine carcasses was 159/2120 (7.5%). Total incidence in cattle was 149/2000 (7.45%), whereas it was 10/120 (8.33%) in buffalo carcasses. Concerning gender, the overall prevalence of Sarcocystis infection was 127/1790 (7.09%) in male and 32/330 (9.69%) in females bovine carcasses. The highest detection rate of Sarcocystis lesions was from the esophagus (76.3%) followed by throat muscles (35.3%), tongue (33.8%), and diaphragm muscles (18.71%). Macrocysts from cattle were identified to Sarcocystis hirsuta, whereas Sarcocystis fusiformis was identified from buffalo carcasses. By microscopic examination, 18 (36%) of 50 female cattle carcasses harbor Sarcocystis sp., whereas 11 (22%) of buffalo carcasses were harbored Sarcocystis microcysts.

Conclusion: A high incidence of Sarcocystis infection was detected among slaughtered bovines in El-Kharga abattoir, Egypt. Sarcocystis macrocysts were a higher incidence in female elder animals macrocysts were identified to S. hirsuta in cattle and S. fusiformis in buffaloes. Sarcocystosis constitute a major cause of economic losses at El-Kharga abattoir. Beef meat may carry health risks to consumers.
