About 30 years ago, I learned to consistently put the toilet seat down after spraying most of my urine into the bowl.
With the tradies doing renos and using the loo, I had to remind the boys, house full of females, close the lid.
But should people, regardless of gender, close the seat before flushing?
I have anecdotally noticed more media references of a recommendation to close the lid before flushing, so I asked Dr. Don.
That’s Don Schaffner of Rutgers University, podcaster with Chapman, and friend of the barfblog.
(He gets paid to look up this stuff, I don’t, I’m just curious.)
Don replied within hours to say that it looks like there is some pretty good science to show this is more than a theoretical risk.
“On toilet surfaces, gut-associated taxa were more prevalent, suggesting fecal contamination of these surfaces.”
My risk-based recommendation?
And be careful (At home, I pee sitting down to minimize the mess, and complaints. That’s minimize, not eliminate).
