ENVIRONMENTAL HEALTH IMPLICATIONS OF WASTE GENERATED IN ABATTOIRS - A CASE STUDY KADUNA SOUTH LOCAL GOVERNMENT AREA OF KADUNA STATE

ABSTRACT

This project aimed at finding out the Environmental Health Implications of Waste Generated in Abattoirs- A Case Study of Kaduna South Local Government Area of Kaduna State. Questionnaire, personal observations, oral interview and labouratory analysis were used to collect the data. Water samples were taken from the selected area to assess the level of PH, BOD, Colour, Test, and Odour. Out of the total number of households which is 3418, 358 were randomly chosen to obtain their views. Based on their responses, it is observed that the water of the selected abattoirs is significantly polluted by abattoir effluents. The result is further supported by labouratory analysis which is then compared with FEPA acceptable limit. The labouratory results revealed that the various samples were contaminated with E.Coli and other enteric bacteria which pollute the water biologically beyond permissible limits. The presence of coliform staphylococcus aurens was confirmed in the water to an extent that it may be injurious to human health. The presence of various form of bacteria which cause Anthrax, Q-fever, Campylobacteriosis, Ornithosis, Botulism, Staph, Salmonellosis, Brucellosis are confirmed. These pose a serious public health problem. Therefore, the following recommendations were made: Enforcement of existing health and hygiene regulations guiding abattoir operation; provision of adequate wastes disposal facilities to cater for both solid and liquid waste; and also the provision of modern abattoir.
