The abundance of pathogenic organisms in soil at the vicinity of Ugwuaji landfill site in Enugu Metropolis was investigated during dry (December 2018 – February 2019) and wet (June – August 2019) seasons using standard procedures. Experimental soil samples from the vicinity of the landfill were randomly collected in triplicate from 6 different locations labelled SL1, SL2, SL3, SL4, SL5 and SL6 at distances of 100 m, 200 m, 300 m, 400 m, 500 m and 600 m away from the site, respectively. The control soil samples were randomly collected from a sampling location labelled SLC about 2 km away from the landfill. The occurrences of bacteria isolates were higher in wet season than dry season while fungi isolates were higher in dry season than wet season. The level of contamination of soil in the vicinity of the landfill site was generally higher in the wet season than in dry season. The relative percentage abundance of these organisms decreased with increasing distance away from the site. Statistical analysis showed that in both seasons the frequency of occurrences of the isolated pathogenic microbes in experimental soil differs significantly (P<0.05) when compared with occurrences in control soil. Therefore, the application of proper waste management practices at the landfill site is urgently needed to protect the environment and to minimize possible public health risks.
