Rice, a versatile staple, can be easily overlooked when left out overnight. However, its susceptibility to bacterial growth makes proper handling crucial to avoid food poisoning. In this guide, we’ll explore the risks associated with leaving cooked rice out, how to store it safely, and signs of spoilage.

How Long Can Rice Be Left Out?

Cooked rice is prone to Bacillus cereus growth, making it unsafe if left at room temperature for over two hours. In warmer conditions, such as above 90°F, this timeframe reduces to just one hour. An exception is sushi rice, with added vinegar, safe for up to six hours.

Leaving Rice Out Overnight:

Cooked rice left out overnight should never be consumed, as reheating won’t eliminate bacteria or toxins. Even sushi rice with vinegar exceeds the safe time frame if left out overnight.

Soaking Uncooked Rice Overnight:

Soaking uncooked rice overnight is different from leaving cooked rice out. Uncooked rice, not yet vulnerable to bacteria, can be healthier when soaked. Many recipes recommend soaking rice before cooking, removing pollutants and aiding digestion.

How Long Will Rice Stay Good In the Fridge?

Despite refrigeration, cooked rice has a short lifespan. Consume it within 3-4 days of cooking, reheating to 165°F before consumption. Freezing rice doesn’t reset the clock; it should also be consumed within 3-4 days after thawing.

Preventing Spoilage:

Properly cooled and stored rice is the key to preventing spoilage. Ensure fully cooled rice before refrigerating, and consider dividing or spreading it for faster cooling. Freezing leftover rice is a convenient option, providing portioned servings for future use.

How Do I Know If Rice is Spoiled?

Err on the side of caution if in doubt. Spoiled rice may have bad smells, including fishy, foul, sour, or rotten odors. Discoloration, a wrong taste, or illness post-consumption are additional signs of spoilage.

What Happens If I Eat Spoiled Rice?

Eating spoiled rice risks food poisoning, leading to symptoms like nausea, vomiting, diarrhea, and fever. Vulnerable populations, such as children or those with health conditions, face increased risks.

Is Pre-Prepared Microwavable Rice A Safe Option?

Pre-prepared microwavable rice can be a convenient and safe option, offering flexibility and portion control. It’s a practical choice for those prone to forgetting their rice.


Properly handling and storing rice is essential to avoid foodborne illnesses. Follow these guidelines to ensure your rice remains safe for consumption, protecting yourself and others from the risks associated with spoiled rice.
