Characteristics of slaughterhouse wastewater and its suitability to be land-applied for agriculturaluse were investigated. A survey was sent to slaughterhouses located in Ontario, Canada, and their methods of disposal weredetermined. Wastewater samples were taken from randomly selected slaughterhouses and were analyzed for their chemicalconstituents. The meat type, presence of blood and the commodity type had a highly significant impact on the biological oxygendemand (BOD5), total Kjeldahl nitrogen (TKN) and total solids. (TS). As TKN and BOD5 can be decreased by the reduction of TS in the wastewater, it is important that the slaughterhousesremove as much TS from the wastewater as possible. The presence of blood increased Co and Mo levels in the wastewater.The concentrations of 11 metals present are very low and if the wastewater is land applied properly, the risk to the environment is minimal.
