The Dirtiest Place in the Airport is Not What You Think

Often thought of as the filthiest of places, an airport public restroom may not necessarily be the dirtiest place in the airport. What could be worse? Security bins? Ticket counters? The place where you and thousands of other travelers have to take your shoes off?

Curious as to what spot actually is the dirtiest, InsuranceQuotes, a Texas-based insurance company, went to three major U.S. airports and airline flights and performed 18 tests across six different surfaces. Samples were sent off to a laboratory to find the average number of colony forming units (CFU) or bacterial or fungal cells per square inch.

Basically, the more CFUs there are, the more contaminated a surface is.

Self-check-in kiosks is often the dirtiest place in the airport.The results were surprising: self-check kiosks contained the highest level of CFUs with 253,857. Armrests at the gate were second with 21,630 followed by water fountain buttons with 19,181.

It makes sense: all day, countless people tap the same screen to get their tickets, unaware the dirtiest place in the airport is right at their fingertips. The self-check-in kiosk is the one place nearly everyone is forced to touch. Not surprising then is that the world’s business airport, Hartsfield-Jackson, was the germiest of all three subject airports. Just one kiosk alone came back with 1 million CFU.

Remember that “filthy” restroom? An airport toilet contains 172 CFU on average.

The close proximity of other passengers and stale air in the airplane is blamed for illnesses, but maybe it’s the pre-flight contact instead. We may never know.

So what can you do to protect yourself?

The best way is, of course, complete avoidance whenever possible. Check into your flight from your smartphone or at home on your computer (just your germs there).

That being said, if you do find yourself at the airport, here are a few tips for cleaner traveling:

  1. Barefoot is bad! Walking barefoot through security makes you more susceptible to germs and infections like athlete’s foot, so always wear socks through the airport security line.
  2. Hand sanitizer. Carry TSA-approved size mini bottles of hand sanitizer for quick clean ups after touching dirty screens.
  3. Resting your elbows on armrests at your gate is comfortable, but if you wipe them down with disinfectant wipes first, they’ll be comfortable and clean.
  4. No brainer: always, always, always wash your hands after using the restroom. Public or private. Airports and everywhere. Always. Use soap and warm water for seconds; that’s “Happy Birthday” twice or the Alphabet song once.

“Safe travels” has a whole new meaning when you say ‘bon voyage’ to germs.
