Dangerous to health: Some foods should not be heated up in the microwave. From rice and mushrooms to animal products, leftovers should be used up within the following day or two.
When reheating poultry, it should be completely cooked through or seared. If germs and bacteria have formed due to incorrect or too long storage, they will not be completely killed when warmed up. However, make sure to distribute the food as flatly, evenly and covered as possible on the plate or in the bowl.
