ABSTRACT
Abattoir wastes discharged untreated into water bodies has caused significant damages to the aquatic ecosystem. A kilometer distance of Ogun River by Kara cow market was sampled within the area of high slaughtering of animals and discharge. A total of 110 respondents were selected for the administration of questionnaire using purposive sampling method. Fish samples were obtained from fishermen landed catches and preserved on an ice box while water samples were collected in one litre bottles from the sampling points for laboratory analysis for wet and dry seasons. The results showed that untreated abattoir wastes were discharged into the river. The abattoir waste has 97.3% direct effects on the river with 99% chances of polluting the surface water. There were significant (p<0.05) differences in the concentration of the microbial organisms at the different sampling points with regards to their occurrence and distribution. The observed bacteria include Pseudomonas spp., Bacillus spp., Escherichia coli, Klebsiella spp. and Staphylococcus aureus. In summary, it will be logical to say that the abattoir wastes discharged into the water body has contaminated it due to the presence fecal indicator microbials capable of causing sickness to humans and affecting the health conditions of fishes in the water body.
