Why Leftover Rice Can Make You Sick
Cooked rice contains spores of Bacillus cereus that survive cooking. When rice is left at room temperature, these spores germinate and produce toxins that cause vomiting or diarrhea. The risk increases the longer rice sits out.
How Long Leftover Rice Is Safe to Eat
Refrigerate cooked rice within two hours of cooking. In the fridge, it is generally safe for three to four days. Reheat it to steaming hot before eating, and avoid leaving it at room temperature for extended periods.
Safe Handling and Storage Tips
Store rice in shallow, airtight containers to cool it quickly. Do not keep it warm for hours in a rice cooker. For longer storage, freeze rice in portions. Visit the U.S. Department of Agriculture for more guidance on safe rice handling.
