Dirtiest places on planes and in airports
6. Airport washroom stall locks – In an effort to determine which airport and airplane surfaces have the most bacteria, website Travelmath.com sent a microbiologist to take 26 samples from five U.S. airports and four flights. The biggest surprise of all? There are far dirtier places than washrooms. Tested airport stall locks were found on average to have 70 colony-forming units (CFUs) per square inch -- 30 times fewer than the dirtiest spot on the list.
