The last thing you’re probably expecting to ingest with your Starbucks iced coffee are fleeting amounts of poop. But according to a test conducted in the United Kingdom by the BBC’s consumer series, "Watchdog," some of the largest caffeine peddlers in the world were found guilty of harboring poop bacteria in their ice, meaning your favored cold brew may have more in common with the bottom of a toilet bowl than you’d like to imagine.
According to the tests, ice samples from three prominent chains in the UK -- Starbucks, Costa and Nero -- were found to contain fecal coliforms, albeit to varying degrees. Seven out of 10 samples of Costa ice contained poop bacteria, while three out of 10 ice samples from Starbucks and Nero were also contaminated. It's worth noting, though, that this is a small sample size for chains with thousands of locations.
