“…Previous studies indicated that there is an increasing use of waste waters from human and animal wastes for irrigation of Agricultural produce in Nigeria and this has led to contamination of vegetable and salad crops with helminth eggs (Okoronkwo, 1998). Similarly, studies of irrigation water as well as the stream and sediments also revealed the presence of parasitic helminthes (Okoronkwo & Onwuliri, 2001). Parasitic diseases that have been associated with solid wastes include malaria, myiasis, amoebiasis, filariasis, ascariasis and taeniasis.…”
