Do you think soda tastes best from a fountain? A team of microbiologists from Hollins University have found that extra flavor might just be coliform, a fecal bacteria. 48% of the sodas they tested from soda fountains had the bacteria. Even better news, the study also found that most of the bacteria were resistant to antibiotics. From the abstract: "...Coliform bacteria was detected in 48% of the beverages and 20% had a heterotrophic plate count greater than 500 cfu/ml. [...] More than 11% of the beverages analyzed contained Escherichia coli [E. Coli] and over 17% contained Chryseobacterium meningosepticum. Other opportunistic pathogenic microorganisms isolated from the beverages included species of Klebsiella, Staphylococcus, Stenotrophomonas, Candida, and Serratia. Most of the identified bacteria showed resistance to one or more of the 11 antibiotics tested."
