The bug that can grow in rice is called bacillus cereus. Personally I would never eat reheated rice, or rice that has been standing around to go cold and then sit at room temperature.
I'm a bit of a bacteria geek cos microbiology is my job
I eat reheated rice all the time. I'm fine, I usually fridge it and then reheat from the fridge.
Although, my dad - who is 71 in Dec- always eats rice that is reheated. He leaves it standing overnight in the colander and then eats it the next day. He has NEVER had food poisoning. EVER.
I find this debate on rice very interesting.
I love rice and my SW diet was based on pasta and rice, perhaps that's why I didn't lose much weight.
When I cook rice I keep it in the fridge for a few days, heat and reheat it, nothing ever has happened to me. I think you are talking about rice in resturants, people have known to become ill after reheating the "takeaway rice". My 2 cents worth
