From the article:
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.
No the fuck it does not. I’m one of those people that actually cleans theirs. Seeing any kind of spill in the microwave, or stuff on the walls, grosses me out.
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.
Seems like it’s pretty much like any other surface in your kitchen, it requires regular cleaning.
