From December 2007 to June 2008, a parasitological research among the population of Parque Industrial Huaycán, in Ate Vitarte district, province of Lima, Peru was performed, in order to determine the prevalence of intestinal parasites and risk factors as well as to determine the sero-prevalence of human Toxocariosis. The coprological samples were analized by the Direct Method with lugol, rapid Sediment in Lumbrera`s glass, and Kinyoun dye for coccidia; and ELISA technique for sero-diagnose of human Toxocariosis. For soil samples, glass sediment and the Baermann-Lumbrera`s technique were used. The Graham method was used for the diagnosis of enterobiosis. Prevalence of enteroparasitism was 74.24%. The most prevalent species of pathogenic protozoa were: Blastocystis hominis Brumpt, 1912 (52.51%) and Giardia lamblia (Lamb, 1859) (18.16%); and among helminths, Enterobius vermicularis Limaeus, 1758 (9.50%). The risk factors which favor the persistence of intestinal parasites were: to poor environmental sanitation, as houses with soilfloor which lack drinking water and sewers, and throw their waste on a heap of rubbish. Also, bad hygiene habits, as playing with soil, or not washing their hands before eating, or after using the toilet. Another factor of risk is having animals at home, especially dogs. The sero-prevalence of human Toxocariosis in the studied population was of 30.23%, where as 23.26% of the population were marked as suspectful for the disease. The factors of risk related to with the human Toxocariosis were: dogs kept in the house and houses with soil floor.
