Many people need to be made aware of the potential risks associated with improper handling and cooking of rice. Understanding these risks and how to avoid food poisoning can ensure that rice remains a safe and delicious part of your diet. 

Food Poisoning From Rice

Food poisoning occurs when you consume contaminated food that contains harmful bacteria, viruses, or toxins. One of the primary culprits behind food poisoning from rice is a bacterium called Bacillus cereus. This bacterium produces heat-resistant spores, which can survive even when the rice is cooked.

According to research by the Cleveland Clinic, there are about 63,400 cases of food poisoning from Bacillus cereus annually in the US. Bacillus cereus spores begin to reproduce rapidly when cooked rice cools and enters the “food danger zone” of 40 to 140 degrees Fahrenheit.

These bacteria can lead to gastrointestinal issues such as vomiting and diarrhea, with symptoms typically lasting for about 24 hours.

Proper Handling of Rice From Purchase to Consumption

Prevent food poisoning from rice begins at the store. Here are some essential tips:

  • Check Packaging Integrity: Always inspect the rice packaging for any signs of damage or holes. Damaged packaging can be a sign of contamination.
  • Verify Expiration Dates: Check the expiration date on the rice package. Although rice has a long shelf life, knowing that you’re buying fresh stock is essential.
  • Purchase From Reputable Sources: Buy your rice from well-known and trustworthy suppliers to ensure high quality.

Once you’ve purchased your rice, store it properly to keep it safe:

  • Excellent, Dry Storage: Keep uncooked rice in a cool, dry place to prevent mold and bacteria from growing.
  • Airtight Containers: Use airtight containers to store your rice. This helps protect it from moisture and contaminants.

Cooking Rice Safely

Properly cooking rice is critical for eliminating any harmful bacteria. Here’s how to cook rice safely:


  • Rinse the rice thoroughly under cold water.
  • Use a 2-to-1 water-to-rice ratio.
  • Bring the water to a boil, add the rice, and reduce the heat to a simmer.
  • Cover and cook for 18-20 minutes until the water is absorbed and the rice is tender.


  • Rinse the rice.
  • Use a rice steamer according to the manufacturer’s instructions, usually requiring a similar water-to-rice ratio.

Rice Cooker:

  • Rinse the rice.
  • Follow the rice cooker’s instructions, which generally involve adding the rice and water and setting the cooking time.

The rice should reach a temperature of at least 165 degrees Fahrenheit to kill bacteria.

Rice can still pose a risk even after cooking if not handled correctly. Follow these steps to ensure safety:

Rapid Cooling:

  • Spread the cooked rice in a thin layer on a baking sheet to cool it quickly.
  • Transfer the cooled rice to an airtight container and refrigerate immediately.



  • Reheat rice to a temperature of 165 degrees Fahrenheit before consuming.
  • Avoid reheating more than once to prevent bacterial buildup.

Avoiding Common Mistakes

Preventing food poisoning requires vigilance. Here are some common mistakes to avoid:

Leaving Cooked Rice at Room Temperature:

  • Leave cooked rice out for up to two hours. Bacteria can multiply rapidly at room temperature.


  • Use separate utensils and containers for raw and cooked rice to avoid cross-contamination.

Using Spoiled Rice:

  • Check for signs of spoilage, such as a sour smell or discoloration, and discard if found.

Additional Tips for Safe Rice Consumption

Maintain good hygiene and follow these extra tips to ensure your rice is safe:

Clean Storage Containers and Equipment:

  • Regularly clean and sanitize rice storage containers and cooking equipment to prevent contamination.

Fresh Water and Ingredients:

  • Use fresh water and ingredients each time you prepare rice to ensure safety.

Identify Spoiled Rice:

  • Be vigilant for signs of spoilage, such as an off smell or unusual color. If in doubt, throw it out.

Cultural and Regional Practices

Different cultures have unique ways of preparing rice that can enhance its safety:

Japanese Method:

  • In Japan, rinsing rice thoroughly and soaking it before cooking helps remove excess starch and potential contaminants.

Indian Method:

  • In India, rice is often parboiled, which partially cooks the rice and kills bacteria before the final cooking.

Chinese Method:

  • Many Chinese households use a rice cooker, which provides a consistent and safe cooking environment.

These traditional methods have been backed by science for their effectiveness in reducing the risk of food poisoning.

Addressing Myths and Misconceptions

There are many myths about rice and food poisoning. Here are some clarifications:

  • Myth: Reheating rice is always safe.
  • Fact: Reheating rice can be safe if done correctly, but it must reach 165 degrees Fahrenheit and should not be reheated multiple times.
  • Myth: All rice is safe to eat raw.
  • Fact: Raw rice can contain harmful bacteria and should always be cooked thoroughly.

Stay informed with reliable sources and follow safe practices to enjoy your rice meals without worry.


Rice is a versatile and beloved food, but handling, cooking, and storing it safely is essential to avoid food poisoning. 

  • Select and store rice carefully.
  • Cook rice thoroughly.
  • Cool and store-cooked rice promptly.
  • Follow safe reheating practices.

You can enjoy your rice dishes safely by implementing these steps in your daily routine.
