In a test of ice cubes from 49 fast-food and casual-dining restaurants and hotel bars in the city and suburbs, the Chicago Sun-Times found that more than one of every five samples contained high levels of bacteria.
Samples taken at three of the restaurants contained an undetermined amount of fecal coliform, according to the findings of a government-certified laboratory that performed tests on the samples for the newspaper.
By comparison, a water sample taken from a toilet in a men's room at the Sun-Times tested cleaner than the ice obtained at 21 of the restaurants and bars.
Better yet, make the ice out of the toilet water. Just don't pick the yellow cubes.
