ABSTRACT
Slaughterhouse processes consist of several pollutants, including condemned meat parts, aborted fetuses, animal trimmings, horns, undigested ingesta (paunch contents), bones, and hairs. In contrast, liquid parts consist of blood, dissolved solids, urine, gut contents, and wastewater from slaughter operations and floor cleaning. It has been reported that Abattoir wastes can have negative impacts on the areas surrounding them by causing pollution and public health concerns. Therefore, this research was initiated with the main objective being to evaluate the Parasitological and Microbiological Characteristics of Wastes Generated and the Impact on Water Sources next to the Abattoir in Lurambi sub-county Kakamega County. Laboratory investigations were carried out for two months during the dry and wet seasons. Wastewater samples from five slaughterhouses and water samples from water sources next to the abattoirs were examined using standard procedures. The bacteria isolated were E. coli, P. aeruginosa, K. pneumoniae, E. faecalis, and S. dysenteriae. Bacterial concentrations cfu/100ml of abattoir effluents ranged from 3.17 × 106 of TC. 3.94x104 of FC, 2.84x104 of E. faecalis, 8.65x104 of E. coli, and BOD of 828.04mg/l.Fungi isolated were., Aspergillus niger, Fusarium oxysporum, Penicillium spp, Aspergillus fumigatus, Saccharomyces cerevisiae, Aspergillus flavus. Parasites isolated from samples of effluent and water were Balantidium coli, Trichomonas hominis, Ancylostoma duodenale, and Ascaris lumbricoid. It was concluded that the abattoir wastes were unsuitable for discharge to the environment and resulted in water pollution near abattoirs that may cause serious waterborne diseases. The baseline information obtained from the results can be used by government authorities such as National Environmental Management Authority and researchers.
