Abattoir wastewater quality in South Western Nigeria

Abattoir wastewater may be defined as water that has been used in the cleaning up of slaughtered cattle, sheep, goat and pig carcasses, the floor of slaughter hall, personnel and slaughter equipment. Abattoir wastewater is characterized by presence of high concentration of whole blood of the slaughtered food animals and suspended particles of semi-digested and undigested feeds within the stomach and intestine of slaughtered and dressed food animals. Since slaughtering and dressing of food animals take place in an abattoir, it becomes easier to refer to the wastewater from this industrial system as “abattoir wastewater”. This study determined the physico-chemical and patho-bacteriological qualities of abattoir wastewater from Bodija Municipal Abattoir in Ibadan city, South Western Nigeria.
