Analysis of the Microbial Quality of Locally Consumed Palm Wine Sold in Elele Community of Rivers State Nigeria
European Journal of Nutrition & Food Safety,
Palm wine is generally consumed due to its nutritive composition to the human body system particularly when fresh and unfermented state. A total of 20 Palm wine samples obtained from two different locations in Elele community of Rivers state, were analyzed for their microbiological qualities. A ten-fold serial dilution method was used. For Total Aerobic Plate Count (TAPC) nutrient agar was used, MacConkey for coliform count (CC), Eosin methylene blue for Escherichia coli count (EC), and Potato dextrose agar for the fungal count. Microbial counts in the palm wine sold in the drinking bar were higher than that of the palm wine tapper. TAPC, the sample from the drinking bar has a mean value (6.73+ 0.22 log10cfu/ml) which was higher than the value obtained from the palm wine tapper (6.70+0.15log10cfu/ml). The coliform count of palm wine from the drinking bar was (6.57+ 0.10log10cfu/ml) but not significantly different from those with minimum counts (6.56+ 0.9log10cfu/ml) obtained from the tapper. Escherichia coli of palm wine from drinking bar were (5.73+ 0.23 log10cfu/ml) which were higher than (5.71+ 0.18 log10cfu/ml). The Fungal counts of palm wine sampled from the drinking bar were higher but not significantly different from those obtained from the tapper. Bacteria isolated from the two respective palm wines sampled included Staphylococcus spp 50% and 30% respectively, Klebsiella spp 20% and 30% respectively, Proteus spp 40% and 10% and 30% respectively, Aspergillus spp 30% , 10% and Saccharomyce cerevisae 20% and 30% respectively. For the analysis of variance, bacteria and fungi count was not significant. Consumers of palm wine are advised to purchase the product from the tapper to reduce the chances of contamination.
