[Parasitoses of food origin in Tunisia].

About diet parasitosis, the author distincts three origins of contamination: telluric, proteinic, and both. The telluric parasitosis are the most frequent, intestinal (by helminths or protozoairs) as visceral (hydatidosis). The frequence of these parasitosis is subjected to changes in the different areas, in intensity, but also in the nature of identified parasite. Toxoplasmosis, transmitted by the two mods occurs in Tunisia. The population average percentage protection is however no sufficient to prevent the risk of contamination during pregnancy.
