Cooked rice is one of the most common leftovers, but it's also one of the most misunderstood when it comes to food safety. Here's how long it lasts, how to store it properly, and when to throw it out.
Cooked rice lasts 4-6 days in the fridge when stored properly in an airtight container. After 6 days, the risk of bacterial growth (specifically Bacillus cereus) increases significantly.
Uncooked rice can contain spores of Bacillus cereus, a bacteria that can cause food poisoning. These spores survive cooking. If rice is left at room temperature for more than 2 hours, the spores can multiply and produce toxins that cause vomiting and diarrhea. The toxins are heat-resistant, so reheating won't make the rice safe.
Yes. Cooked rice freezes well for up to 6 months. Portion into freezer bags, press out the air, and flatten for easy stacking. Reheat from frozen in the microwave with a splash of water.

No. Rice left at room temperature for more than 2 hours should be discarded. Bacillus cereus spores can multiply rapidly at room temperature.
Yes, if it's been stored properly in the fridge. Reheat until steaming hot throughout (165°F/74°C). Don't reheat rice more than once.
Retrogradation. The starch molecules recrystallize as the rice cools, making it firm and dry. Adding a splash of water when reheating restores moisture.
