Abstract
Slaughterhouse wastewater has a complex composition and very harmful to the
environment. The abattoir wastewater at mandate market Ilorin, Kwara State was studied for
possible pollutants and biotreatment using indigenous microorganisms. Microbial count was
done using pour plate techniques and the physicochemical analyses were done using
standard method. Total bacteria count was between 1.60x104
- 2.43x107 Cfu/ml while fungi
count was 1.63x103
- 1.8x106Cfu/ml. Findings showed that the various water samples were
contaminated with E. coli and other enteric bacteria. This result revealed that the
temperature, pH and electric conductivity ranged from 27.8 - 28.40oC, 7.07 - 7.19, and 103 -
887μS/cm respectively, Total Dissolved Solid (TDS) and Total Suspended Solid (TSS) were
between 1350.20 - 880 and 76.5 - 2266.0 mg/L respectively, the Dissolved Oxygen (DO),
Biochemical Oxygen Demand (BOD) and Chemically Oxygen Demand (COD) ranged
between 4.5 - 0.2, 54.4 - 130 and 700 - 1240 mg/L respectively. The presence of E. coli and
Streptococcus faecalis in the abattoir wastewater may be attributable to the high load of
animal excreta in the wastewater.. Most of the fungal isolates were also soil-inhabiting
microorganisms as well as common spoilage organisms associated with beef industry.
