Is described a review of the epidemiological aspects of teniasis and cysticercosis. Cysticercosis is caused by the development of the larval form of Taenia, wich results in the Cysticercus in tissues, and is transmitted through ingestion of Taenia eggs. Human and animal cysticercosis are a great socioeconomic problem in many countries. It is a endemic zoonosis and is widespread in developing countries especially in rural areas. Larval invasion of the central nervous system constitutes a serious complication in humans. Cysticercosis is one of the great public health problems in developing countries and the neurocysticercosis is considered the most common parasitic disease of the human central nervous system. The freezing of meat for six days in temperatures below -15ºC, its adequate cooking, meat inspection and treatment individual patients infected with adult worms in endemic areas are the main control measures.
