[microbiologist hat on]
type of rice makes no diff
and it's not an aflatoxin (that's peanuts), it's a toxin from a bacteria that loves to grow in warm or tepid rice.
I avoid rice that's been kept warm in restaurants, buffets etc, but am happier if I've cooked it myself so I know what's happened to it. Often cook, chill and reheat with no adverse effects.
Can indeed cause nasty food poisoning though.
