Commonly present in the muscle of animals are the tissue cysts of Toxoplasma and Sarcocystis. The aim of this study was to determine the presence and levels of Toxoplasma/Sarcocystis tissue cysts in retail pork, beef, and mutton throughout the Michiana area. A total of 36 samples from the three species of interest were exposed to a digestive solution mimicking stomach conditions. The solution consisted of 0.75% pepsin, 0.86% NaCl, and HCl adjusted to a pH of 1-2. The digested samples were then strained through several layers of cheesecloth, centrifuged, and examined for the presence of parasites. Toxoplasma/Sarcocystis were detected in all species of meat with an overall prevalence of 55%. Although not ubiquitous in every meat product, improper preparation could leave the consumer at risk of infection.
