I don't know about the dishes but according to my memory of something I read a while ago (can't look things up right now), the kitchen sink and kitchen brushes aren't much cleaner than anything in the toilet; and actually, kitchen washcloths/sponges tend to be worse than toilet surfaces.
So, maybe don't put toilet brushes in the dishwasher but definitely don't put in kitchen washcloths either. Not sure what this means about us washing dishes by hand with a sponge either. And maybe don't put in used washcloths along your clothes in the washing machine.
