Abstract
Sarcocystis is one of the most prevalent protozoan parasites in the striated muscles of livestock slaughtered for food such as cattle, sheep and goat. Meat that is heavily infected may be condemned as unfit for human consumption. The aim of this study was to determine the prevalence of Sarcocystis spp. in slaughtered cattle in Tabriz, northwest of Iran. The prevalence of Sarcocystis spp. infection was investigated in 670 cattle, slaughtered from April 2013 to October 2013 in the Tabriz abattoir, Iran using naked eye examination for macroscopic Sarcocysts, and peptic digestion, muscle squash, squeezing methods for microscopic types. Muscles from oesophagus, tongue, heart, diaphragm and cervical and abdominal of 670 slaughtered cattle were examined for Sarcocystis spp. cysts. The prevalence of microscopic Sarcocystis spp. cysts in cattle was detected in 100 % and there was detected in macroscopic cyst 8.2 % in examined cattle. There were no significant differences among the infection rates of the different organs (P > 0.05). There were no significant differences among the infection rates of the different ages (P > 0.05). The prevalence of macroscopic infection in the oesophagus was higher than that of the other organs (P < 0.05). The infection rate was independent of sex (8.25 % in males and 8.13 % in females, P > 0.05). This suggests that meat should be cooked sufficiently, since a macroscopic inspection may not provide true results. Also, it has of great importance the farmers to be trained not to feed their dogs and cats with uncooked meat, and the abattoir remnants to be burned, in order to be effectively broken of infection cycle between the intermediate and the definitive hosts in Tabriz city, northwest of Iran.
