Microwaves may not heat food evenly. Several studies have shown that this can lead to food poisoning. One study showed that of 30 people who reheated roast pork that had been left unrefrigerated for many hours during a picnic, 10 who reheated the pork in a microwave contracted salmonella -- compared with none out of 20 who reheated the pork using a conventional oven or skillet.
Self-defense: Use a microwave only to reheat meat that has been thoroughly cooked and properly stored. Do not cook previously uncooked meat in a microwave oven.
