Leftover fried rice is a primary culprit, said Philip Tierno, a microbiologist and clinical professor at New York University Langone Health. After the rice is cooked, it is often left at room temperature for more than two hours to cool before frying it with other ingredients. Cooling the rice ensures that the finished fried rice won’t get clumpy or become soggy. But reheating it doesn’t get rid of the toxins the bacteria have already produced.
