Microwave ovens are great time-savers and can help you in a bind. These days microwave ovens can cook, grill, defrost and reheat any foods. These features can really help when grills or convection ovens take time to reheat foods. Microwaves can be very effective in the reheating process if used correctly.
Here’s the deal, microwaves don’t actually kill bacteria.
The microwaves instead create heat that is able to kill bacteria in foods. But microwaved foods can cook unevenly because of irregular shapes or differences in thickness. Think about a solid frozen meal compared to reheating a soup. Even turntable-equipped microwave ovens can cook unevenly and leave cold spots where harmful bacteria can survive.
