What causes airborne bacteria?
There are numerous bacteria, fungi and other organisms in the environment that find their way onto bathroom and kitchen fixtures. Most are not pathogenic (disease causing). They are found in soil, food and on animals, and they may become airborne. Some thrive on moisture and need little else to grow. They may be noticed at the water line in toilet bowls or toilet tanks, on faucets, in sinks or on shower tiles. They sometimes appear jellylike and are gray, black or even pink in color. The pink colored one is interesting and often gets the attention of the customer. This is the bacteria serratia marcescens and is from the environment not the water supply.

Room or whole-house humidifiers can be the source of airborne bacteria. Regular cleaning, periodic disinfection with household bleach or cleaner and adequate ventilation are necessary to control these organisms.
