well i simply never use the microwave for anything....it makes the food taste stale and turns water green.....besides that stuff can blow you up if you leave the microwave on and its open........well my parents sometimes reheat the dinner in the microwave but we usually cook new food anyways....

i posted japan not china i dont know who said that or if it was misinterpreted
i dont beleive it anymore only when i was a kid
mics were first invented in america in the early 50's and were the size of a fridge...just for info sake

i stopped using microwave oven a couple years ago. makes lunch at work a bit blah but....there is WAY TOO MUCH evidence that hasn't been studied..well at least in the u.s. anyway, about the questionable effects it has on food AND the food containers. it is the almighty dollar that is talking here.....FOLLOW THE $$$$$$$$$$
