Ahh, an article for all of us who combine OCD with a healthy aversion to germs:
"For this project, Jasmine visited five fast food restaurants near the University of South Florida. She collected ice samples from self-service dispensers inside the restaurants, as well as ice from drinks served through drive-through windows. She also collected samples of toilet water from those restaurants.
She placed the samples into sterile containers and tested them at a lab at the H. Lee Moffitt Cancer Center, where she volunteers with a USF professor.
Jasmine found that in four of the five restaurants, the ice that came from the self-serve machines had more bacteria than the toilet water. Three of the five cups of ice from the drive-through windows had more bacteria than the toilet water.
Of the bacteria found in the ice, three out of the five restaurants tested positive for fecal coliform or E. coli, organisms that come from the feces of warm-blooded animals."
Whoa, how the hell are the "feces of warm-blooded animals" getting into restaurant ice?! Ick.
So this would be... Reason #4309 why NOT to support the fast food business. Or, at least, to avoid the ice machines.
