ABSTRACT

Summary In various sorts of composts with sludge from wastewater treatment plant and garbage Nematodes (Ascaris spp, Trichuris

spp, Toxocara spp) and Cestodes (Hymenolepis spp) eggs were recovered but no Trematodes eggs was found. In 60% final samples obtained after 120 days of compostage, Helminth eggs were recovered. This contamination rate is important but study about viability of eggs are needed before the real importance of these composts as a transmitting medium for parasitological diseases can be adequately assessed (13).
