Reheating rice can unleash a multitude of nasties however treated correctly there’s no issue. Cool the cooked rice under cold water and then into the fridge, as long as you get it good and hot when you fry it then there’s no problem. The trouble comes when cooked rice is left at room temp and not fully reheated. I make batches of fried rice and freeze it, defrost and then fully reheat and all is good.I have a fear of keeping cooked rice to use the next day, believing that it harbours some kind of dread food poisoning, am I mistaken ?
Edited to add:
NHS seems to agree.
You can get food poisoning from eating reheated rice. However, it's not the reheating that causes the problem, but the way the rice has been stored before it is reheated.
