Comparative Study Of The Microbial Quality Of A Selected Brand Of Sachet And Bottle Water Sold In Umuahia Abia State, Nigeria:- Daniel Ofofon E
ABSTRACT
Safe and potable water supplies in urban centres
in Nigeria are still inadequate in spite of over five decades of independence
and several efforts from various governments. This study was aimed to assess
and compare the microbiological qualities of bottle and sachet packaged water
sold in Umuahia Metropolis. A total offive (5) known sachets water and five
known bottle water samples were purchased from different location in Umuahia
Metropolis and analyzed using microbiological standard method. The bacteria
isolate were Escherichia coli, Klebsiella pneumonia, Staphylococcus aureus,
Shigella species, Proteus mirabilis and Enterobacter aerogenes while the fungal
isolate were Aspergillus Niger, Fusarium oxysporum, and Aspergillus flavus. The
mean Microbial load of sachet water sample is higher compare to the bottle
water sample. They were slightly high and exceeding the recommended standard
limit for water 1.0 x 102 CFU/ml. The result ofthe presumptive coliform
indicates that bottle water has <2 coliform which means there is no coliform
contamination found in bottle water compare to sachet water it was observed
that the sachet water contain more bacterial isolates than the bottle water
sample. The dominant bacterial species was Escherichia coli with percentage of
55.7% while the dominant fungal species was Aspergillus niger having percentage
occurrence of 32.5%. The microbial contaminants could be as a result of
improper sterilization of the water before packaging or contamination due to
poor handling during production, transportation or sales of such products.
