Through this process feacal-oral diseases are transferred to man unfettered.

Akpata and Ekundayo (1978), Helasi-kun (1981), cited in Ajayi and Akonai (2005:163) asserted that the discharge of raw sewage into the lagoon has important health implications. This insanitary act is facilitating the spread of feaco-orally transmitted sanitation related diseases. Infections such as diarrhea, cholera, and typhoid that account for significant mortality are contracted through house flies, contaminated hands, food, and water, eating and cooking utensils. It is not difficult for edible materials to be exposed to faecal matter in Lagos metropolis, because the polluted lagoon account for more than 70 per cent of fish and other sea foods consumed daily by Lagosians. Therefore eating fish caught in the polluted Lagos lagoon increases the risk of contracting feaco-oral diseases. The main thrust of this paper is to examine the ecological impacts of discharging raw sewage into the lagoon with a view to identifying most healthy and sustainable approach.
