When left out at room temperature, rice is an ideal environment for a foodborne pathogen, called Bacillus cereus (2) , to thrive and produce toxins. These bacterial spores survive even in the heat. Therefore, heating isn’t sufficient to kill off the spores.
The bacteria is a potential cause of food poisoning, causing vomiting, cramps, and diarrhea. The symptoms of food poisoning from spoiled rice occur in the first 30 minutes or up to 6 hours. The symptoms will usually subside after a day.
For normal adults, food poisoning shouldn’t be too hazardous a problem to handle. However, people with a compromised immune system might bear more serious health consequences, like those who have diabetes, chemotherapy, HIV/AIDS, organ transplant, or alcoholism.
Overall, even if your immune system might be sufficient enough to fight off bacteria from food poisoning, you should always take precautions about consuming leftovers, especially for those with weakened immune systems.
This explanation will provide you with more detail about how Bacillus cereus affects your rice.

1. Refrigerating Your Rice
If you’re still asking whether rice should be refrigerated, then the answer is yes. However, you’ll need to learn the proper preparation for the best result.
Refrigerated rice can be stored for 3-4 days. As said above, you should check your refrigerated rice by smell and observation. But it is also important to know the correct ways to store your rice in the fridge, so keep scrolling the page for more information.
What You’ll Need:
- Airtight containers or containers with plastic wrap
- Something with a large surface, such as a big plate or a baking tray
The key to refrigerating rice is cooling quickly to remove steam as steam results in the water. If your rice is soaked in water when refrigerated, it will create an ideal environment for bacteria to grow and spoil your rice. Here’s a step-by-step guide to refrigerating your rice.
Step 1: Preparing Rice for Storing
Cool the rice by placing it on a clean plate or a baking tray. Spread the rice gently, don’t apply too much pressure on the rice as it might get mushed.
The thinner the spread, the quicker it will cool down. It should take 5-10 minutes for the rice to cool down.
Step 2: Make Sure The Rice Is Cool
After the rice has been completely cooled, you can check if it has cooled down by checking for steam coming off the rice.
Use a clean spoon to scoop the rice into the clean container. You could use airtight containers/Ziploc bags or just a simple bowl but make sure to cover with plastic wrap.
Step 3: Mark The Storing Date to Ensure You Remember Correctly
Use a marker or pen to write down the date on the container. This will help ensure you know how long the rice has been kept. This step is particularly important if you have busy schedules or are forgetful.
Finally, place the rice in the cool compartment of the fridge and remember to eat it soon.
What should you do to store cooked rice in the fridge precisely? Do not miss this guide.
2. Freeze Your Cooked Rice For Longer Shelf Life
Besides refrigerating rice, you can also freeze it. Freezing rice will expand the shelf life of cooked rice which can keep your food safe for up to 6 months.
Make sure you treat your rice right before putting it into a device. You can apply the same steps as storing rice in the refrigerator.
In addition, you can also try storing uncooked rice in the freezer. With the proper preparation, your rice will last for a very long time this way.

3. Using A Rice Cooker to Store Your Rice
A rice cooker is a widely popular household applicant, especially in Asian households. This convenient device cooks your rice to perfection (as long as you follow the precise water and rice ratio in rice pokers) and keeps it warm.
After being cooked, the rice cooker will automatically turn to the “Keep Warm” mode. The heating element inside will be adjusted to a suitable temperature to keep the rice in the pot warm and safe.
So what is the ideal time to keep rice in rice cookers? With a rice cooker on “Keep Warm” mode, the rice can be left in there for up to 12 hours at room temperature unattended, which means you can leave your rice overnight in this kitchenware.
However, it is not the ultimate tip to do so because this might affect the rice quality. The longer you keep rice in the cooker, the drier the rice will be. This is due to the exposure of heat to the rice, which causes the evaporation of moisture, decreasing its fluffy texture and becoming crisp.
NOTE: A helpful trick for preventing dried rice in the rice cooker is giving a splash of water to the rice and switching the cooker back to “Cook” mode. This will transform your rice back to its fluffy and moist state.
When using a rice cooker, the best time range to enjoy the cooked rice is within 5-6 hours. So serve it immediately after scooping your rice out of the pot if possible.
After 12 hours, you can reserve the rice by refrigerating it. But the rice shouldn’t be kept there longer than a day and should be reheated for consumption.
Tips To Reheat Your Rice For Further Use
Reheating cooked rice is not too hard to do. For example, there are many ways to reheat fried rice. Regardless of what kitchenware you use, ensure the internal temperature of your rice reaches 165 F degrees for safe eating (3) . And here are some tips with steps for doing that.
1. Use A Rice Cooker
A rice cooker can reheat your stored rice and give your rice the original texture effortlessly. On the other hand, there are certain differences between rice cookers and instant pots, they are both acceptable to warm your food.
Step 1: Warm the Rice at Room Temperature Before Reheating
To reheat using a rice cooker, take the rice out from the fridge or freezer. Let it rest at room temperature for around 15-20 minutes.
Step 2: Heating Rice in Rice Cookers
Transfer the rice from your container to the rice cooker. Add a splash of liquid, water, or broth, to the rice cooker. Then close the lid and turn on “Cook” mode.
Compared to cooking rice, reheating will take a shorter time. After the rice has been reheated properly, the rice cooker will automatically turn to “Keep Warm” mode. You can enjoy your rice then.
2. Use A Pot or A Pan
Using the pot to reheat your rice requires virtually the same steps as using a rice cooker. However, the rice cooker doesn’t need too much attention. By using a pot/pan, you need to monitor your food until it’s completely reheated. Here are some steps to ensure you do it right.
Step 1: Let The Rice At Room Temperature Before Reheating
Take your rice out and let it sit at room temperature. It should take around 15-20 minutes.
Step 2: Reheat Rice in A Pot/PanOver A Stove
Put the rice in a pot, and add a splash of liquid, water, or broth. Put a lid on and place the pot/pan over the stove on low heat.
Step 3: Check Rice Condition Frequently During Heating Time
After 5-7 minutes, open the lid to check the rice. Stir the rice to break clumps up and avoid burning at the bottom of the pot/pan.
3. Use Microwave
If you want to reheat your food in a microwave, it’s important to use microwave-friendly containers and a damp towel. The damp is crucial as it creates steam to prevent the rice from drying out and gives it a fluffy bite.
Step 1: Warm The Rice At Room Temperature Before Reheating
Take your rice out and place it in a microwave-friendly container. Break rice clumps, if any.
Step 2: Place A Damp Towel On Your Rice
Add a splash of liquid, water, or broth. Place the damp towel over the rice and make sure the towel covers the surface of the rice and leaves no open spots. Then place your food in the microwave.
Step 3: Microwave The Rice
Set it for about 2 minutes and fluff the rice in between until they are steamy and hot completely.
NOTE: For large objects such as a bowl, it’s likely that the middle is still cold while the edges are warm. So make sure to stir the rice for the portion to be thoroughly reheated.
Check out this instruction to reheat the rice perfectly with a microwave.
4. Use Oven
Another kitchen device that can work well to reheat your food is an oven. Similarly, you should add a bit of water and use an oven-safe dish to keep the rice.
Remember to break any rice lump before putting it into your oven. You should use a lid or aluminum foil to cover your rice dish. Set the temperature at 300 F degrees for about 20 minutes until they are heated through.
