Mythbusters busted this myth long before studies. Turns out that air pressure is enough to push the particles flying from the bowl despite the lid, because the toilet lid isn't a good air tight seal, and the air is pushed out due to water volume increase.
So basically closing the lid doesn't help.
Ok it doesn't 100 percent stop it or it doesn't help at all? Because I always assumed something as small as a poop bacteria could get through the little cracks but I also assumed having it go through the cracks was better than having it go through the massive entire open bowl where it seemed like more would spray out. Did they comparison test the amount of bacteria on surfaces or just prove that some gets through?
Edit: obviously I could be wrong but it also seems like having the lid down would direct more bacteria to lower surfaces whereas having it open would give an easier path to higher surfaces where we tend to keep things like toothbrushes.
Probably depends on the amount of air pressure generated. Then any throttled venturi opening will increase the velocity through it.
Which is to say, closing the lid could make it shoot farther through the opening.
But that would also direct it horizontally vs vertically, which is probably preferred.
Tldr; Control toothbrush contained 98% bacteria or close enough. Make of that what you will. Basically, close your tootbrush in the cupboard.
Ick. Thanks for the info.
Didn't Mythbusters just prove that the particular kind(s) of fecal bacteria they checked for are present everywhere at all times?
See not being a pessimistic asshole, everything is shit.
It helps me not drop my toothbrush in there in our tiny bathroom though.
