I got trained in this when i worked at the nursery.... Rice is a major culprit for food poisoning, more so than meat, but mainly because people are less careful with it, and are unaware how much bacteria in can have.
If cooked rice is stored in the fridge, and re-heated properly before use, it shouldn't be a problem. Its just not something you'd want to leave out of the fridge, or eat cold the next day.
Then again, i'm with you cathface, in that this is how i treat all leftover food
- well that or freeze it.
