Hey guys Tara here for Dnews - and if you're gonna be doing some summer traveling soon

- then it's worth reminding yourself how gross airplanes actually are.

A new study from Auburn University finds that microbes can live up to 8 days inside an airplane,

just long enough to infect you and ruin your entire vacation.

A team of researchers sterilized 6 different surfaces on the inside of an airplane - and

then purposefully infected them with a host of microbes, ranging from E coli to MRSA,

the antibiotic-resistant staph infection that's estimated to occur in around 1-2% of US citizens.

Their goal was to see how long these microbes could survive in an airplane cabin, where

they're most likely to proliferate, and what the chances are of them actually infecting

someone. Turns out - there are a few different places

bacteria love to thrive - and the worst one is the airplane seat pocket. MRSA was especially

attracted to this area, surviving up to 168 hours - or around 8 days. E. coli, on the

other hand, tends to thrive in the rubber armrest, and was able to survive up to 4 days

there. The 4 other germiest areas of the cabin were

leather seats, plastic window shades, plastic tray tables, and toilet handles.

Despite what you might think, though - the dirtiest places aren't always the most likely

to transmit infections. The researchers in this study found that the most porous surfaces

- like the rubber arm rests - do harbor the longest-living bacteria, but also have a lower

risk of infection because the microbes tend to bury themselves deep into the pores of

the material. On the flipside, non-porous surfaces - like

the toilet handle - hold fewer microbes with shorter lifespans, but they're way more likely

to infect you than a place like the seat pocket. Other studies on airplane germs have come

up with some interesting conclusions. A 2007 study found that 60% of airplane tray tables,

tested positive for MRSA. Other experts caution against staying in aisle seats - since they

come into contact with more people, and are thus more likely to transmit infectious microbes.

Obviously keeping yourself hydrated is important too, since the low humidity on board can lower

our natural defense system. But the overwhelming consensus, across all studies, is to avoid

the airplane restrooms at all costs. You may remember a while back, there were

several cases of fecal bacteria discovered in the water supply of airplanes. As a result,

the EPA passed the Aircraft Drinking Water Rule which ensures safe and reliable drinking

water for passengers and crew. But germs like E Coli can still survive in airplane sinks,

as long as people who are infected with it, are washing their hands. And you know that

tiny airplane soap isn't gonna get rid of that stuff.

Now obviously, the ideal solution would be for airlines to adopt the same sanitation

strategies as places like hospitals, which use peroxide vapors and UV light to disinfect.

But until that happens - if you're really concerned about getting sick - your best option

is to avoid the bathroom altogether. And if you MUST use it - wash your hands thoroughly,

and then douse yourself in hand sanitizer afterwards. Maybe not your whole body, but

at least your hands. Hopefully this hasn't scared you out of traveling

this holiday weekend - but to be honest, I kind of hope it has. I'm gonna be traveling

myself, and I wouldn't hate having an empty seat next to me. You know, for hygiene purposes.
