(NEWSER) – Designated drivers aren't always the teetotalers one might hope them to be, a study suggests. Researchers tested 1,071 subjects exiting bars in a Florida city on a series of Friday nights over a three-month period; 165 of the subjects called themselves designated drivers. Of those, 35% had had something to drink: 17% of them had blood alcohol content between 0.02% and 0.049%, and another 18% had BAC of at least 0.05% (the NTSB's newly desired drunk-driving limit).
(Jason Howerton) A new investigation by The Daily Mail claims ice from McDonald’s, Burger King, KFC, Starbucks and other fast food chains was more bacteria-ridden than toilet water. In fact, six out of the 10 restaurants they tested had high levels of bacteria in the ice.
The Mail surveyed various establishments in the U.K. and conducted scientific tests that found more bacteria in the ice than toilet water at the same location.
There is some silver lining though. While disgusting, the report found no “immediate health danger.”
“Samples from McDonald’s, KFC, and Nando’s were suspected to be dirtied by things like a dirty ice machine, while Burger King responded to its results by saying it was probably an employee who didn’t wash his or her hands,” the Yahoo! blog Shine reports.
Starbucks reportedly had a “satisfactory” level of bacteria in its ice, according to scientists.
(NEWSER) – Paper towels may not be the most environmentally friendly way to dry your hands, but they are the most hygienic. Australian scientist Cunrui Huang reviewed 12 studies on hand-drying, and found paper towels were the superior method in a public restroom, because they dry your hands more quickly than air dryers, and bacteria spreads more rapidly on wet hands, the AAPreports. "A hand dryer takes 30 seconds longer to achieve about the same dryness as a towel," says Huang. "This is important because most people spend less than 20 seconds drying their hands."
