A total of one hundred (100) brands of
sachets and one hundred (100) brands of bottle water samples were collected
from different locations in Abuja Metropolis and were analyzed
physico-chemically and microbiologically.
The total count of most of the sachet
water samples ranges between 0.32 x 102 and 1.95 x 102 CFU/ml, exceeding the
limit of 1.0 x 102 CFU/ml. The MPN of coliform counts ranged from 1 to 16 cfu
/100 ml of sample. Total number of isolates 502, 201 (40.04%) Escherichia coli,
52 (10.36%) Streptococcus faecalis, 50(9.36%) Pseudomonas aeruginosa and 199
(39.64%) Klebsiella Species. The dominant bacteria isolates were Escherichia
coli, Streptococcus faecalis, Pseudomonas aeruginosa and Klebsiella Species.
The entire bottle water samples analyzed showed
no bacterial growth. Bacteriological analysis showed that 10/100 (10%) of the
samples of sachet water tested showed positive coliform counts. These
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. There were no traces of Heavy metals
and all other chemical parameters were within permissible limits.
