RedTracker| If you think bottled water is bacteria-free, think again. Your tap water could be healthier. Researchers in Montreal found that heterotrophic bacteria counts, in more than 70 percent of bottled water samples, exceed the recommended limits specified by the United States Pharmacopeia (USP).
Even though Montreal’s tap water is among the cleanest in the world, smart Canadians assume that bottled water is better. The study came after complaints of bad tastes in the bottled water.
“Heterotrophic bacteria counts in some of the bottles were found to be in revolting figures of one hundred times more than the permitted limit,” says (Sonish) Azam, researcher on the study. In comparison the average microbial count for different tap water samples was 170 cfu/mL.
Azam stresses that these bacteria probably aren’t dangerous, but the “high levels of bacteria in bottled water could pose a risk for vulnerable populations such as pregnant women, infants, immunocompromised patients and the elderly.” Read on at Science Daily.
