Bacteriological characteristics of abattoir effluents (wastewater), abattoir water source, and water bodies receiving abattoir wastewater were investigated in Abuja, Nigeria using the multiple-tube fermentation technique. Source of water to the abattoirs and the usage of water bodies receiving abattoir effluents were determined using questionnaires. Bacterial counts ranged from 4.8 × 106 to 5.8 × 105 /100 mL of total coliform (TC), 8.2 × 104 to 3.2 × 104/100 mL of Fecal coliform (FC), 5.2 × 104 to 2.0 × 104/100 mL of Fecal streptococcus and 1.2 × 104 to 2.0 × 103/100 mL of Escherichia coli for abattoir effluents 6.6 × 105 to 6.0 × 105/100 mL of TC, 6.2 × 104 to 1.8 × 104/100 mL of FC, 1.8 × 104 to 6.0 × 103/100 mL of F. streptococcus, and 4.8 × 103 to 6.6 × 102/100 mL of E. coli for water bodies receiving abattoir effluents 100 m downstream. TC bacteria counts for abattoir effluents exceeded recommended limit for discharge into surface water in Nigeria. No significant difference (P
