You don't have to be a germophobe to want to slip on rubber gloves when you enter an airplane cabin.
A new study confirms once again that various surfaces in the cabin of a commercial plane have many times the amount of bacteria than an average kitchen counter. But the latest study found that surfaces in airport terminals can have even higher germ counts than those in the planes.
The highest number of colony-forming units of bacteria per square inch were found on those increasingly popular self-serve ticketing kiosks that are popping up in terminals around the country, including Los Angeles International Airport.
Folks from the website Insurancequotes.com conducted swab tests on the surfaces of three major airports and three airlines and calculated the bacteria or fungal cell counts for several surfaces. The website declined to disclose the names of the airports and airlines that were tested.
The highest germ counts in the planes were on the flush button on the toilets — 95,145 colony-forming units, followed by 11,595 CFUs on the tray tables and 1,116 CFUs on the seat buckles, according to the study. The typical kitchen counter measures 361 CFU, according to the National Science Foundation.
The highest germ counts in the terminals were found on the screens of airport kiosks, 253,857 CFUs, followed by 21,630 CFUs on bench armrests and 19,181 on drinking fountain buttons, the study said.
Nearly three years ago, a similar study said the buttons on the drinking fountains in airport terminals had the highest germ count. Since then, airlines including American, Southwest and United have added hundreds of new self-serve kiosks to speed up the check-in process.
