Researches have found that self-service check-in screens at airports have over 1,000 times more bacteria on them than toilet seats.
A recent study found that the average self check-in screen has 253,857 CFU, with one particularly dirty check-in screen having a count of one million CFU per square inch.
In comparison, the average toilet seat contains just 172 CFU.
CFU (colony-forming unit) is a unit used to estimate the number of viable bacteria or fungal cells in a sample.
The study, commissioned by Insurance Quotes, conducted 18 swab tests across six surfaces at three major US airports and aeroplanes.
The results also revealed that the armrest on departure lounge seats are also far from germ-free, with the average having a CFU reading of 21,630.
Whilst the airport water fountain button had an average reading of 19,181 CFU.
On board the plane, the average toilet flush button has an average 95,145 CFU.
