Whether you call them thongs, flip-flops or jandals, the simple rubber sandals could be a breeding ground for bacteria too. They allow easy access to oxygen, skin cells and oils, dirt and moisture. Eighty per cent of the population already have Staphylococcus aureus - found on sandals after being work for 4 days - on their skin, in their nose and armpits, yet this microbe aureus could make you pretty sick if it gets into a cut and into your blood, and if your immune system is not robust.
Some of bad bacteria can be even found in bottled water or in Fast Food Soda Fountains (see this article published in International Journal of Food Microbiology). 48% of soda fountains at fast food restaurants contain coliform bacteria. More than 11% of the beverages analyzed contained Escherichia coli and over 17% contained Chryseobacterium meningosepticum. Other opportunistic pathogenic microorganisms isolated from the beverages included species of Klebsiella, Staphylococcus, Stenotrophomonas, Candida, and Serratia.
