How quickly can bacteria grow in cooked rice?

Bacteria in cooked rice can grow very quickly, doubling their numbers every 15-20 minutes in the temperature "danger zone" (40°F - 140°F), meaning it should be refrigerated or kept hot within two hours, or one hour if it's a hot day (90°F+). This rapid growth is due to spores of Bacillus cereus surviving cooking; if left at room temperature, these spores can germinate and produce toxins that cause food poisoning, a condition known as "fried rice syndrome".
