Revealed: Dirtiest spot on a plane, and it's impossible to avoid it!

• Passengers must carry hand sanitizers.

A new study has revealed the dirtiest surface in a plane, and this will certainly make passengers skeptical of sitting on their seats comfortably.

The study by Marketplace states that the plane seats' headrests are covered with most germs as compared to other surfaces aboard aircraft and even consist of E. Coli bacteria which indicates 'fecal contamination'.

This makes it vulnerable for passengers to come into contact with deadly germs regularly. It was proven by Marketplace, which conducted tests on 18 short-haul flights across Air Canada, WestJet, and Porter Airlines between Ottawa and Montreal. Over 100 samples were collected from the plane seat's headrest, seatbelt buckle, seat pocket and tray table, as well as the inside handle of the toilet door.The samples were sent to the University of Guelph's lab to be analysed by microbiologist Keith Warriner, who told CBC, "I was really amazed about how much we actually recovered from them. Some of them are scarier than others." Among the germs found in the samples, it was revealed that there were traces of E. coli bacteria on both the headrests and seat pockets.

Jason Tetro, who works in infection control, said, "I was shocked. Honestly, I have looked at planes, and I travel so much on planes, I'm aware of so many of the different places [where germs could be found]. But then I saw what you showed me with the headrest. And even I, the germ guy, went 'ew'."

Although the chances of catching an infection are still low, passengers must carry 100ml hand sanitizers in hand luggage to minimize the risk as well as wash hands before eating or touching face, according to reports in Mirror.
