As I said earlier we must each find our own balance.

I've been cleaning toilets for over 60 year and learned at a very early age to avoid splashing and slopping because it stained the white tile, so I'm pretty careful and use a mop style cleaner, not a brush. Also I calculate my exposure as fewer than 10 minutes per week. so it's not a concern for me.

On the other hand, I mask when raking, using a blower and handling garden soil and mulch. I probably spend 8 hours a week or more doing that so I figure it is a high risk situation for me.
And I would definitely wear a mask if I was cleaning a cat box, but we're pet free.

By the way I have been off antibiotics for 3 1/2 years without reinfection.
