A study about the prevalence of Sarcocystis sp. in bovine, ovine and goat cattle have been performed using the Trichinoscopy method into heart and esophagus tissues. The results showed that 76 samples of heart tissues from bovine positive over a total of 85 samples (89.5[%]); will 122 sampless from ovine were positiye over a total of 134 samples <91.04[%]). In the same tissue of goat only 33 samples (52.4[%]) Sarcocystis was found. In esophagus the parasitism average was as follow: 2[%] in bovine; 39.8 in ovine and 76.2 in goat. These results achived trat the mayor parasitism in bovine and ovine is located into the heart; whilst in goat the esophagus is the tissue more infected Therefore a hig parasitism by Sarcocystis sp. has been registred in the meat of cattle used as a human food.
