Abstract
The microbial quality of an abattoir effluent discharged into Waterside River in Abawas investigated. Samples were taken from the abattoir effluent, and from upstream and downstream of the receiving water body, and were examined for pathogenic microorganisms. The mean counts of the different isolates were obtained. The isolates include; Escherichia coli, Pseudomonas sp., Klebsiella sp., Salmonella sp., Shigella sp., Staphylococcus aureus, Enterobacter sp., Aspergillus sp., Rhizopus sp. and Penicillium sp. The ranges for microbial counts at room temperature and at 37oC were;9.8×104 to 2.2×107 cfu/ml(total aerobic plate count), 7.5×104 to 1.7×107 cfu/ml (total coliform count), 3.4×103 to 7.0×104 cfu/ml (Salmonella count), 2.2×103 to 5.6×104 cfu/ml(Shigella count), 2.0×104 to 5.4×105 cfu/ml (Escherichia coli count),7.0×103 to 6.7×105 cfu/ml (Staphylococcus aureus count) and 2.0×103 to 5.0×104 cfu/ml (total fungal count). In all the samples analyzed at both 37oC and at room temperature, the effluent had the highest count, while the upstream had the least count. The results show the negative impact of the abbatoir effluent wastedischarge on the receiving water body. The presence of the isolated pathogens is of public health importance and indicates poor abattoir hygiene. Thus, adoption of appropriate abattoir wastewater treatment measures are recommended.
