“…Esses autores observaram que, dependendo da época de amostragem, P. aeruginosa podia ou não estar presente nas fontes e que mesmo não havendo a contaminação da fonte por este microrganismo, ocasionalmente a bactéria esteve presente nas enchedeiras e produto final. De acordo com WARBURTON & DODDS [29], tal fato pode ser resultado da colonização por P. aeruginosa nos equipamentos. Desta forma poderia ser usada como indicadora das boas práticas de fabricação (no que se refere à limpeza e sanificação), uma vez que freqüentemente pode não ser detectada na fonte, mas ser detectada nos equipamentos e produto acabado.…”

“…The potential danger associated with sachet water is contamination, which is a factor of the source of the water itself, treatment, packaging materials, dispensing into packaging materials and closure (Omalu et al, 2010). Under prolonged storage of packaged water at favorable environmental conditions, total aerobic heterotrophic bacteria can grow to levels that may be harmful to humans (Warburton et al, 1992).…”

ABSTRACT:The purpose of this study is to investigate the effect of storage on the physicochemical status and bacteriological quality of sachet water produced and sold in Abeokuta metropolis, Nigeria. Ten brands of sachet water were collected within 24 hours of production and stored at ambient temperature. Sub-samples were drawn from the stock samples immediately for physico-chemical and microbiological analyses and after two months. Physical parameters were determined by instrumental methods. Cationic and anionic constituents were determined by standard titrimetric and spectrophotometric methods, trace and heavy water were determined by Atomic Adsorption Spectrophotometer. The study revealed that all the brands of water analyzed were physically and chemically wholesome and met the WHO standards. Five brands (50%) of the water had total viable and coliform count above the recommended count of 100cfu/m and zero cfu/ml, respectively. pH values increased in all brands to acceptable WHO limits within 2 months of storage except for sample 3 and 4 which decreases below the acceptable limit. Majorly dissolved oxygen and nitrate values decreased through the investigation period. Total and faecal coliform appeared in 50% of sachet water samples analyzed immediately after production and were no longer detected after storing for two months except for sample 4. Results of the experiment indicate that 60% of the brands analyzed met the WHO guideline limit for drinking especially for the physico-chemical parameters while the majority failed in the microbiological essay when stored at ambient temperature for the two-month investigation period.

“…Another reason is a common belief that mineral waters have beneficial medicinal and therapeutic effects (Warburton, Dodds, Burke, Johnston, & Laffey, 1992). Apart from the use of bottled water as drinking water, it has found wide usage in infant formula preparation, reconstituting other foods, also for cleaning contact lenses, skin care and filling humidifiers.…”
