Why not to eat rice left out?

If left out for an extended period, it's safer to discard it to avoid potential health issues.

What is the toxic rice syndrome?

One of the most common bacteria found in fried rice is Bacillus cereus. It is a spore-forming bacterium also commonly found in soil and the environment. Upon contamination, these bacteria can grow in the food and produce toxins that can cause food poisoning – this is known as the “fried rice syndrome”.

How quickly do bacteria grow in rice?

Bacteria can grow rapidly in temperatures between 40 and 140 degrees, so if the rice is left sitting on the stove or countertop for more than two hours, those spores will grow, producing a toxin that could make you sick with vomiting and diarrhea.

The global mortality rate for B. cereus infection is 0.9 %. Food poisoning cases account for 94.31 % (5786/6135) of the total infections, with a mortality rate of 0.05 %.

What kills Bacillus cereus?

Cooking contaminated food at recommended temperatures destroys the vegetative cells of B. cereus. Heat-resistant endospores of this bacteria are more likely to survive cooking and start growing again (germinate) when the food is cooled gradually over an extended period of time.

Which food poisoning comes on quickly?

Bacteria like Staph and Bacillus cereus can make you sick quickly, within 1 to 7 hours. These bacteria produce fast-acting toxins in foods (such as meat or dairy for Staph, and starchy foods like rice for B. cereus).
