Soil contamination with parasite eggs was surveyed in some public areas in Taiz, Yemen. The objective of this study was to identify contamination rate of soil collected from public areas in the rainy and dry seasons (summer and winter seasons respectively). Forty-two soil samples were gathered from different public areas, of which 18 (42.9%) have parasite eggs. The parasite eggs were detected by zinc sulphate solution, flotation method and/or filtration method. Four species of nematode eggs and larvae (Ascaris lumbricoides, Toxocara spp. Trichuris trichiura, and hookworm) and three species of cestoda (Hymenolepis nana, Taenia saginata and Dipylidium caninum) were detected. A. lumbricoides and Toxocara spp. eggs were predominant. Multiple species of helminth eggs and larvae (free living and plant nematodes) were found. The author assumes that the soil of public areas in Taiz may be contaminated by both human and animal faeces.
