Hilldodger – you get more dangerous bugs in your kitchen as well. Litseriosis and salmonella for starters.
Only when introduced by poor food hygiene practises, and Listeriosis is a disease not a 'bug' 😉
Point is, 'toilet bacteria' are more likely to be involved in person-to-person disease transmission, especially in public facilities where usage is sufficently high that the bacteria need only to survice rather than actively reproduce.
research done in hospitals actually showed contaminants spread further with the lid down as it act like a nozzle concentrating the aerosol effect. Hence hospital toilets rarely have lids nowadays
Strange that the NHS website should say
"When you flush, germs from the toilet bowl travel as far as six feet, landing on the floor, the sink and your toothbrush. A study showed that significant quantities of microbes float around the bathroom for at least two hours after each flush. Always put the toilet lid down before flushing."
You could eat your own poo and drink your own urine and not get sick
That comment is useless without pictures 😉
