Hardy bacteria found living inside microwaves

How much does bacteria in a microwave impact the food that is being microwaved? Is there enough aerosolized bacteria in there that it would land on your food with enough effect?

Mere presence of bacteria doesn't mean there's action that needs to be taken.

Quote from one of the authors:

“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. [1]

So I would not worry too much.
