The taeniasis-cysticercosis complex is a disease of great importance to public and animal health, and human beings play an important role as the only definitive hosts that develop taeniasis. Cysticercosis can affect pigs, which are infected by the larva of Taenia solium, cattle, which are infected by the larva of Taenia saginata and, accidentally, humans, who can act as an intermediate hosts (T. solium), developing cysticercosis in their tissues, with neurocysticercosis being the most severe form of the disease. Despite the importance of taeniasis and cysticercosis to public health, animal health and economy in Brazil, the epidemiological reality of the occurrence of zoonoses is poorly understood. In the state of Minas Gerais, most of the data is obtained from official sanitary inspection agencies in slaughterhouses, and little information is based on field data from live animals. In order to assess the epidemiological situation of the taeniasis-cysticercosis complex in small and medium-sized farms in the municipalities of Iraí de Minas, Romaria, Grupiara and Douradoquara, located in the microregion of Patrocínio, in the Triangulo Mineiro region, this study addressed the occurrence of human taeniasis, bovine and porcine cysticercosis, and the main risk factors associated with transmission of parasitic forms of T. saginata and T. solium in the sampled farms. Thus, a cross-sectional epidemiological study was conducted with 68 farms located in rural areas of the four aforementioned municipalities, and these properties were georeferenced. Data collected consisted of 1002 bovine blood samples, 22 porcine blood samples, and stool samples from 119 members of the households and applied an epidemiological questionnaire. The serological diagnosis of animal cysticercosis was performed by screening using the indirect ELISA test, and the suspected cases underwent Immunoblot testing for confirmation purposes. Stool examination was performed by the simple sedimentation method (HPJ). This study found a prevalence of 4.5% of porcine cysticercosis and 4.69% of bovine cysticercosis in the farms of the rural area of the sampled municipalities between July and August 2013. No case of human taeniasis was disagnosed; however, other enteroparasitoses were diagnosed. This study evaluated the association between some risk factors and the prevalence of cases of bovine cysticercosis, in which the variables that were statistically significant were the profession of the person in charge of such farms, income and the water treatment in the farms. From the georeferencing of farms, which generated maps of the collected points and the points diagnosed with bovine cysticercosis. There was the possibility that the transmission of this parasite may occur from the rivers and tributaries that flow along the sampled municipalities from the hydrography of the region. This study identified the prevalence of taeniasis-cysticercosis complex in the sampled municipalities and the results will aid in the prevention and control of this zoonosis in the areas of occurrence.
