Oh, whoops, I don't follow those gov't guidelines ever. Well, I cool leftover rice quite quickly, probably always within an hour. And our fridge is good, and I put it on "high" if cooling lots of food. But I leave rice in the fridge for more than a day.
Pretty sure I've not had food poisoning from rice, though. (I do have a diarrhea bug atm, but haven't had reheated rice for ages.)
Does this apply to rice pudding, too? Store-bought? Home-made?
