What Happens If You Leave Rice in a Rice Cooker on 'Keep Warm' for Over 12 Hours?

Rice cookers' 'keep warm' function is convenient but not meant for long-term storage. Experts recommend keeping rice in 'keep warm' for up to 12 hours; exact safe times depend on the model and temperature settings (check the manual). As time passes, moisture evaporates—rice becomes dry and hard, and the bottom can stick and burn, reducing flavor. More importantly, food-safety risks rise: Bacillus cereus (a bacterium) can multiply rapidly in the 'danger zone' between about 5°C and 57°C. If the cooker’s keep-warm temperature stays in that range, discard the rice. If it maintains above ~57°C reliably, bacterial growth risk is low but quality still worsens. Tips: check the manual, use a food thermometer to measure temperature, and for safety and taste, refrigerate or freeze leftovers and reheat instead of leaving rice on keep-warm for long periods.
