    Bacterial contamination of some fruits sold around selected wastedumps in Owerri metropolis, Nigeria
    (Federal University of Technology, Owerri, 2023-12) Afor Ifeoma Anna
    Analysis of bacterial contamination of fruits sold near waste dumps in Owerri Metropolis were carried out, the various contamination levels were determined on fruits such as; orange (Citru X sinensis), water melon (Citrullu slanatus), apple (Maluspumila), garden egg (Solanumme longena), groundnut (Arachis hypogeaa), pawpaw (Carica papaya) and carbbage. Soil and fruit samples were collected at the market wastedumps and its surrounding in Owerri Metropolis. The soil was collected with a soil augar and was collected at 0cm to 15cm depth. Soil and fruit samples used as control were collected where there was no wastedump. A total of sixty fruit samples and thirty soil samples were collected. Microscopic, physical examination and biochemical tests were carried out; five bacterial species were isolated in the soil and fruit samples: Isolate A; Bacillus Subtills, Isolate B; E. coli; Isolate C; Samonella spp, Isolate D; Staphlacocus spp and Isolate E: Klebsiellaspp. Spread plate method was used in the analysis. The results indicate that the bacterial loads in the soil samples were twice of the fruit samples at each sampling point. The soil sample control had no bacterial growth, the fruit samples used as control gave total of 344 Cfu/g. The total mean of bacterial loads in the soil samples were 45,725,000Cfu and that of fruit samples were 10473.3Cfu. The correlation result gave +1 while the t-test was 1.375(Cal), which shows that the different between the two samples (Fruits and soil) were insignificant. The study recommends that Government should stop people from dumping refuse on open market streets, rather trucks should be provided to carrying refuse from various locations and take them to approved dumpsite. People selling fruits should be encouraged to display the fruits on a table and not on the ground where it can be contaminated.
