Comparative Study of Bacteriological Quality of NAFDAC Registered and Unregistered Sachet Water Sold in Lafia Metropolis
Journal Title: Journal of Advances in Biology & Biotechnology - Year 2016, Vol 10, Issue 4
Abstract
The bacteriological quality of NAFDAC registered and unregistered sachet water sold in Lafia metropolis was investigated. A total of 150 water samples; 100 samples with NAFDAC registered number and 50 without NAFDAC registered number were obtained and analysed using standard Most Probable Number-MPN method and other standard microbiological tests. Results revealed that the registered sachet water had coliform count of 0/100 ml and Physical parameters such as colour and turbidity within the permissible range as provided by the Federal Ministry of Environment- FME and WHO and therefore safe and fit for consumption. The unregistered sachet water, recorded coliform count ranging from 45/100 ml to 550/100 ml indicating high level of contamination with faecal and non-faecal coliforms. The total bacterial count from the unregistered sachet water ranged from 0.4 x 103 cf/ml to 7.9 x 103 cfu/ml. Isolates such as Esherichia coli, Klebsiella spp and Enterobacter species were identified, and E. coli was more prevalent. The presence of these organisms which are of faecal origin, revealed that the water sources (unregistered sachet water) are bacteriologically unfit for human consumption. This calls for regular monitoring and assessment of all sachet water sources in Lafia metropolis.
