Investigating the contamination level of sarcocyst protozoa in the industrial Slaughterhouse of Shuoshtar city by digestion method

Sarcocystis has 130 heteroxenous species, with different cycles and morbidity. The pathogenic species of Sarcocystis for humans are Sarcocystis hominis and Sarcocystis suihominis, in which humans are the definitive host and cattle and pigs are the intermediate hosts. Sarcocystis is a common disease between humans and animals that can be important in terms of health and economy.The purpose of this study is to investigate the level of Sarcocystis protozoan contamination in the industrial slaughterhouse of Shushtar city using the digestion method.In this study, 20 carcass samples were examined randomly and during a period of 2 months, and then, in order to take muscle samples from organs of the esophagus, diaphragm, heart, thigh, and arm were separated with tweezers, pans, and a sterile scalpel.And we labeled the livestock information on the sample and finally, we transferred the samples to the laboratory in a sterile container next to the ice and checked whether they were positive or negative for the sarcocyst parasite in the laboratory with the digestion method.The results showed the highest percentage of sarcocyst detection using a method that can confirm, and also the sensitivity and speed of sarcocyst detection with a higher level digestion method.
