The role of pigsty-privies on Cheju Island, South Korea, in the transmission of helminth parasites from pig to man is discussed with particular reference to Taenia solium. It appears that pigsty-privies reduce the incidence of intestinal nematode infections in the human population but not that of T. solium. It is suggested, however, that the prevalence of the more pathogenic "aberrant" infection (with cysticerci) is reduced, and the efficacy of the Korean government policy of cesspit construction for the control of intestinal parasites of man is questioned.
