Centers for Disease Control Gives the Scoop on Poop in Public Swimming Pools
/Last summer, the Centers for Disease Control and Prevention (CDC) did a public pool study that concluded that feces are frequently introduced into pool water by swimmers.
I debated whether to publish this, well, not particularly pleasant information, but we should all be aware of prepared when we venture out into public swimming areas (such as this compilation of several dozen fun water activities in and around Ventura County).
The CDC collected samples of water from public pool pool filters last summer and tested the samples for genetic material of multiple microbes. Fully 58 percent of the pool filter samples tested were positive for E. coli, bacteria normally found in the human gut and feces.
Finding a high percentage of E. coli-positive filters indicates swimmers frequently contaminate pool water when they have a "fecal incident" in the water or when feces rinse off of their bodies because they do not shower thoroughly before getting into the water.
The study did not address water parks, residential pools or other types of recreational water. The study does not allow CDC to make conclusions about all pools in the United Stat
