Rice is one of the most widely consumed foods in the world, but did you know it can also be a hidden source of food poisoning? If not stored properly, it can develop toxins that cause serious stomach issues. Here’s what you need to know to stay safe.
Rice Can Harbor Harmful Bacteria
Raw food often raises concerns, but cooked rice can be just as risky. The bacteria Bacillus cereus naturally occurs in many foods, but in rice, it can produce toxins if not handled correctly.
Spores Survive Cooking
Boiling rice won’t eliminate all bacteria. Bacillus cereus forms spores that can withstand high temperatures and start multiplying if rice is left at room temperature for too long.
Don’t Leave Cooked Rice Sitting Out
Leaving rice on the counter for several hours creates the perfect conditions for bacterial growth. Once toxins have formed, reheating won’t remove them.
Rapid Cooling Is Key
If you plan to save rice for later, make sure to cool it quickly. The temperature should drop from 65°C to 10°C (149°F to 50°F) within four hours to prevent bacterial growth.
Store Rice Properly in the Fridge
Once cooled, store rice in an airtight container in the refrigerator. It should be consumed within 24 hours to minimize any health risks.
Reheating Won’t Eliminate Toxins
Many people think reheating rice will kill bacteria, but if Bacillus cereus has already produced toxins, heat won’t destroy them. The damage is already done.
Eat Leftover Rice Within a Day
To be on the safe side, consume leftover rice within a day. The longer it sits, the greater the chance of harmful toxin buildup.
How to Reheat Rice Safely
If you choose to reheat rice, do so quickly at a high temperature—at least 75°C (167°F). Use a pan or microwave and ensure the rice is steaming hot all the way through.
Food Poisoning Can Set In Fast
If you’ve eaten rice that has been left out too long, symptoms can appear within 4-6 hours. Common signs include nausea, vomiting, and diarrhea, which may last up to 24 hours.
What to Do If You Get Sick
If you experience food poisoning, stay hydrated to avoid dehydration. Most cases resolve within 12-24 hours, but if you develop a fever, bloody stool, or prolonged symptoms, seek medical attention.
