Sarcocystis sp. infection in slaughtered Brahman Breed cattle was determined by examining skeletal, cardiac and esophageal muscle tissue smear preparation for sarcocysts. Thirteen (10.40 percent) of the 125 slaughtered cattle were positive for mature, young and/or developing sarcocysts called metrocytes. Sarcocysts were noted in skeletal and cardiac muscle tissues of 11 and two Brahman cattle, respectively. Infections were observed in cattle ages three to five years old, predominantly in males which accounts for 11 cases (84.61 percent) compared to two (15.38 percent) positive cases in females. Based on the morphology of the mature sarcocysts, Sarcocystis cruzi is most likely the etiologic agent.
