But for the general public, the implications of the study are simpler. “A microwave is not a pure, pristine place,” Porcar says. It’s also not a pathogenic reservoir to be feared, he says. But he does recommend cleaning your kitchen microwave often — just as often as you would scrub your kitchen surfaces to eliminate potential bacteria.
this isnt about spills. the point is that microwaves arent self-cleaning on a microbial level. even if your microwaves looks prestine, it could still house a lot of bacteria that are capable of surviving radiation.
I don’t like external bacteria that can survive radiation…
