Cysticercosis in the pig.

Taenia solium cysticercosis is still an important parasitosis in rural pigs in many developing countries, México among them. The main causes for the persistence of this condition are lack of hygiene in the rural communities, lack of education of the animal owners, lack of control in the trade of pigs and their meat and lack of conscientious meat inspection. The pig production systems in the marginated areas of Mexico are briefly mentioned and it is stressed that among the important reasons for the persistence of the reproductive cycle of Taenia solium is the fact that appropriate toilet facilities in village dwellings are not mandatory. The diagnostic methods of cysticercosis in the living pigs and in their meat are discussed and the degenerative stages of the larvae as well as methods to test their viability are explained. The treatment of infected pigs and their meat is discussed. Recommendations for control programmes are given.
