Health First – When cooking rice, it is best to estimate the amount needed for each individual, cook it, and consume it as soon as possible. Rice is a perishable food that can cause food poisoning if kept at room temperature for too long. A general rule of thumb is that 1/3 of a cup, or approximately 60 grams, is sufficient for one person.
Ensure that a keep-warm function on your rice cooker maintains a room temperature higher than 140 degrees Fahrenheit if you’ve cooked more rice than you need. Even if you follow the above-described guidelines for storing rice in a rice cooker, freezer, and refrigerator, you should not consume rice with altered texture, color, or odor!

How does rice that has been reheated cause food poisoning? – Uncooked rice may contain spores of the food poisoning-causing bacteria Bacillus cereus. The spores can survive in cooked rice. When rice is left at room temperature, spores can develop into bacteria.
How to Cook Rice in a Rice Cooker (EASY)
Is It Safe to Consume Rice Leftovers? © eleonora galli/Getty Images When cooking at home on a daily basis, cooking in bulk makes sense. This is especially true for frequently consumed foods like rice. There is a common misconception that reheating rice is unsafe.
- You can take the following precautions to ensure the safety of leftover rice: Ensure that you properly cook, cool, store, and reheat leftover rice to avoid illness and food waste.
- Here are some guidelines for extending the shelf life of your rice.
- Rice that has not been cooked may contain Bacillus cereus, a pathogen that can cause foodborne illness.
Frequently, the bacteria is present in the rice, which is then improperly cooked or cooled, allowing the bacteria ample time to grow and thrive in this moist environment. This bacteria prefers moist foods, such as cooked rice, and warmer temperatures for growth (around 85 degrees fahrenheit to 95 degrees fahrenheit ).
- Bacillus cereus is a problem when cooked rice is improperly handled.
- For instance, if rice is left at room temperature for too long, bacteria can multiply to levels that can make you sick.
- For this reason, it is essential to handle rice properly during cooking, serving, cooling, and reheating.
- Preparing Rice The first step in keeping leftovers safe is to wash your hands.
Before touching any food, thoroughly wash your hands with soap and water. Next, prepare rice according to package instructions. This involves bringing the rice to a boil in order to kill any potentially pathogenic microorganisms. There are no guidelines that indicate that rinsing rice for food safety purposes will make it safer to eat.
- Additionally, some individuals rinse rice or soak it overnight prior to cooking to remove some of the starch that causes it to become gummy during cooking.
- While this isn’t necessarily a problem from a culinary standpoint, rinsing or soaking white or parboiled rice can reduce the amount of folate, iron, niacin, and thiamin added during the enrichment process by 50 to 70 percent.
Providing Rice The length of time your rice sits out before serving also affects its safety. Temperatures between 40 and 140 degrees Fahrenheit are optimal for bacterial growth. After rice has been properly cooked, it must be kept hot (at 140 degrees Fahrenheit or higher) to prevent the growth of bacteria.
- If you are serving the rice at room temperature and placing it in a bowl on the table, it must be refrigerated within two hours.
- Rice should be discarded if it is left out for two hours at room temperature or one hour if the temperature is 90 degrees Fahrenheit or higher (such as when dining outdoors).
To avoid leaving your rice out for too long, serve a small portion at the meal and immediately cool and refrigerate the remainder. Refrigerating Rice Rice should be stored at or below 40 degrees Fahrenheit to prevent the growth of bacteria (which is the temperature of the refrigerator).
- Never place hot rice (or any other hot food) in the refrigerator, as it will raise the temperature of the other foods and expose them to the risk of bacterial growth.
- To rapidly cool rice, divide large batches into smaller portions and place them in shallow containers.
- Once the food has cooled to 70 degrees Fahrenheit (room temperature), place it in the refrigerator or freezer.
Rice that has been cooled should be stored in a resealable bag or container. This helps keep bacteria out, retains moisture, and prevents the rice from absorbing odors. Do not forget to label your food with its name and the expiration date. FoodSafety.gov states that leftover rice can be refrigerated for three to four days and frozen for one to two months.
Reheating Rice Leftover If you froze your rice, it is essential that you defrost it properly. It can be defrosted in the microwave and heated until a food thermometer registers 165 degrees Fahrenheit. You can also defrost frozen cooked rice overnight in the refrigerator. The shelf life of thawed rice is three to four days.
You can also reheat smaller portions of frozen rice without defrosting by placing it in a saucepan with a splash of liquid (like water or broth). As long as you reheat the food quickly (in less than two hours), it is safe to use this method. Using a food thermometer, reheated rice should reach 165 degrees Fahrenheit, regardless of the method employed.
- If you have leftover rice after reheating it, you can refreeze it as long as you followed the food safety guidelines outlined above.
- If leftovers are reheated to 165 degrees Fahrenheit and the proper procedures are followed, they can be placed back in the refrigerator and used again within three to four days of when they were originally refrigerated.

How long can rice be stored in an airtight container?
How long can rice be left out without refrigeration? Rice appears to have an indefinite shelf life, similar to many other pantry staples. With the exception of brown rice, cooked rice has a much shorter shelf life than uncooked rice. Therefore, maintaining the freshness and flavor of your rice after cooking is contingent upon following proper storage and handling procedures.
Rice spores can transform into bacteria if the cooked grain is left at room temperature. These bacteria produce toxins that can cause nausea, vomiting, and diarrhea. Every hour that cooked rice is left at room temperature, the probability of bacterial growth increases. After cooking rice, it must not be left at room temperature for more than two hours.
Due to the fact that bacteria thrive at temperatures between 4 and 60 degrees Celsius (39.2-140 degrees Fahrenheit), cooked rice left out for two hours should be discarded. It is ideal to refrigerate within an hour, although some experts say two hours is acceptable.
