How Long Is Cooked Rice Good For?

Why the cooling speed matters as much as the storage length: rice can carry spores of Bacillus cereus, a bacterium that survives the cooking temperature. If cooked rice sits at room temperature for too long, those spores can germinate and produce a toxin that isn't destroyed by reheating — which is why "fried rice syndrome" food poisoning is a genuine, documented risk specifically tied to rice left out too long, not to the rice being old.

Storage guide

Best practice for storing it safely

1. Spread rice out on a tray or shallow container right after cooking to let it cool faster, rather than leaving it in a deep pot.
2. Move it to the fridge within 2 hours of cooking.
3. Store in a sealed, shallow container rather than one deep block, which cools and reheats more evenly.

Signs it's gone bad: a sour or off smell, a slimy or excessively dry/hard texture, or any visible mold. Rice that smells and looks normal but has been left out too long can still be unsafe, since the B. cereus toxin doesn't necessarily change the smell or taste.

Reheating safely: reheat until steaming hot throughout (internal temperature above 165°F/74°C), stirring partway through in a microwave to avoid cold spots, since uneven reheating can leave parts of the rice below a safe temperature.
