Default Rice as a Source of Food Poisoning

I posted this in another thread, but I thought that it's important enough to have it's own thread so more people will read it, especially since the substantial danger of food poisoning from reheated rice -- or from rice that has been allowed to sit unheated for a significant time -- is not widely known. This information from the British Food Standards Agency:

I've heard that reheating rice can cause food poisoning. Is this true?

It's true that you could get food poisoning from eating reheated rice. But it's not actually the reheating that's the problem – it's the way the rice has been stored before reheating.

Uncooked rice can contain spores of Bacillus cereus, bacteria that can cause food poisoning. When the rice is cooked, the spores can survive. Then, if the rice is left standing at room temperature, the spores will germinate into bacteria. These bacteria will multiply and may produce toxins (poisons) that cause vomiting or diarrhoea. Reheating the rice won't get rid of these toxins.

So, the longer cooked rice is left at room temperature, the more likely it is that bacteria, or the toxins they produce, could stop the rice being safe to eat.

It's best to serve rice when it has just been cooked. If that isn't possible, cool the rice as quickly as possible (ideally within one hour) and keep it in the fridge for no more than one day until reheating.

Remember that when you reheat any food, you should always check that it's steaming hot all the way through, and avoid reheating more than once.

This is really good information, Doug! I had no idea rice could grow bacteria so quickly. I will be much more careful now. Thanks.

I've reheated rice more than a day old many times. Haven't been sick yet.

You're not paying attention, Kei. Read it again -- carefully. Reheating isn't the problem, it's how the cooked rice was stored before reheating.

Rice can contain a particular type of bacteria, Bacillus cereus.

Unlike most bacteria, that strain is NOT always killed when the rice is cooked.

If the bacteria do survive cooking, and if the rice is left at room temperature for a significant time (I imagine an hour or more), it will grow.

If the bacteria grow in the luke-warm or cool rice, it will produce toxins -- essentially the bacteria's waste -- which is poisonous and can make you and your family and friends very sick.

Once the toxins develop in the rice, reheating it won't it rid of the poison.

Kei,
I have a compromised immune system, I just can't take chances anymore. Before I wouldn't have given it a second thought, LOL. "Re-heat & Eat" was my motto, I guess it my idea of living dangerously!

Default Re: Rice as a Source of Food Poisoning

I think Kei was reading it correctly, Doug, because that's exactly how I interpreted this statement: "It's best to serve rice when it has just been cooked. If that isn't possible, cool the rice as quickly as possible (ideally within one hour) and keep it in the fridge for no more than one day until reheating."

According to that statement, even when cooled and stored properly you are not supposed to keep it for more than a day before using.

Thanks for the heads up. I will certainly be more careful about refrigerating any potential leftovers right away, but as far as chucking it after one day... I don't know if I buy into that train of thought.

I don't think so. I find the "it's never happened to me" line of argument to be naive. Unfortunately, many people use it to justify all sorts of reckless behavior, such as drinking and driving, driving and texting, and exposing their families to dangerous foods.

Um I did read it. I've had rice sit at room temp, chilled whatever. I've eaten rice almost every day of my life and had it in many conditions and never been poisoned by it. I've done this many times so don't get mad because I'm not running in a panic over this like you are.

Sorry but I'm not going to live my life hiding under the bed in a bubble because some guy on the internet is panicked out of his mind after reading a random article on rice. lol
My advice to you is to never travel to Hong Kong or anywhere outside of your little panic room. You'll probably wet yourself after you see how the food is handled and stored there.

Now go change your shorts.

Maybe because eating is such a personal thing, we are taking this a little too personally. Offering information is always welcome, but no one is required to take it. For some people like Mav, who has special health concerns, it might save him from a very serious illness. For the rest of us, it might save us from vomiting and/or diarrhea sometime. In any event, let's try to keep things cool and take any further disagreements to PM.

Nothing wrong with putting out a health alert on possible food poisoning but there is no need for a poster to get all pissy because somebody isn't as worried about as he is.

I'm hardly panicked; I'm merely passing on information that few are aware of. I certainly wasn't.

Every parent sooner or later comes to appreciate the old saying that you can warn a wise man about fire, but a fool has to get burned.

Enjoy your ignorance, and may you continue to be lucky.

Default Re: Rice as a Source of Food Poisoning

I was actually concentrating on the part about how long it sat out before putting it away. Based on this, I let mine stand out too long before putting it away, I am very lazy in that aspect. Hence the trip to the garbage can for the leftover rice. It was three days old, but that is not what concerned me. It was the amount of time I had left it out on the counter before packing it away, several hours.
I am certainly not panicked about any of this, but I appreciate the information provided and it gives me something to think about and consider in the future. I may even change the way I clean up after meals, putting food away first and right away then cleaning up the dishes and what not.
I too have never gotten sick from leftover rice, or even leftover meats and dishes that I was too slow to put away after the meal, but that doesn't mean it couldn't have happened or that it won't ever happen in the future.
Odds are sometime in our lives we are going to get food poisoning. So while odds are not a guarantee I see nothing wrong with increasing the odds in my favor either.

I think that tummies get used to food. The Mexicans in Mexico don't get sick everytime they drink the water.. either do I but some folks do.
