Un-Hygienic Data on the London Underground

During Autumn of 2000, a team of scientists at the Department of Forensics at University College London removed a row of passenger seats from a Central Line tube carriage for analysis into cleanliness. Despite London Underground's claim that the interior of their trains are cleaned on a regular basis, the scientists made some alarming discoveries:

This is what was found on the surface of the seats:
* 4 types of hair sample (human, mouse, rat, dog)
* 7 types of insect (mostly fleas, mostly alive)
* vomit originating from at least 9 separate people
* human urine originating from at least 4 separate people
* human excrement
* rodent excrement
* human semen

When the seats were taken apart, they found:
* the remains of 6 mice
* the remains of 2 large rats
* 1 previously unheard of fungus
