Abstract:
Impact of indiscriminate discharge of abattoir wastewater has been a major cause of concern
globally due to its negative effect on public and environmental health. Lack of wastewater
treatment plants and guidelines for proper disposal in many developing countries generates other
numerous ecological problems to the affected countries. Its role as a nutrient-provider for
pathogenic microorganisms was highlighted by many researchers. Treatment of abattoir
wastewater remains the main reliable and efficient means of reducing environmental pollution it
may consequently cause. Environmental pollutants released through wastewater by abattoirs may
be complicated due changes brought about by additional substance used during animal
processing. Several methods adopted by abattoirs were reported to be effective. However, the
need for improvement in line with environmentally friendly guidelines is recommended.
