Unfortunately, people do not wash them properly before eating. The climate and topography of south – west Nigeria are suitable for growth of these fruits thought-out the year, using rain during wet season ad irrigation during dry season. These two sources of water was highly polluted with human and animal faced which represent high risk to farmers and consumption of fruits products.
Markets fruits are often contaminated by eggs of human intestine nematodes where human and animal faeces are extensively used as fertilize and refuse waste water. This indirect reserve of river water contains a substantial percentage of munipal refuse and sewage. This practice is gaining prominence in Nigeria as a result of the crowing cost of mineral fertilizer and high demand of basis fruits as a nutrient diet due to poor. Socio – economic condition (Damen and Ban wat 2007).
