I think you're right - the heat will kill just about everything, so why worry I suppose. That said, I do wonder what people do when they wash their chicken - do they stand in the middle of the kitchen and swing it around?? I'm confidant that the few splashes that occur when I wash my chicken are cleaned up thoroughly, and are not left to linger anywhere in my sink, on my counters, or on my chopping boards. That's what's puzzling me.
On the subject of washing eggs - I saw someone on a YouTube video doing this and I couldn't believe my eyes! If you're that worried about eggs, should you really be eating them at all? And where are you buying them from to make you so scared of cracking and breaking them without washing them?? That's completely alien to me.
