Can reheating rice cause food poisoning?

It’s important to know how to reheat any food to avoid the symptoms of food poisoning. Rice is a staple in many people’s diets, and with it being a popular takeaway food, what’s the advice when it comes to heating it back up again – can you keep it for your next meal or should you throw it away?

Reheating rice is a popular choice, especially when people get a takeaway and have some leftover. It’s well known it has the potential to cause food poisoning, so should it be avoided all together or is there a way around it? Rice can be reheated but care should be taken to make sure it is stored properly before reheating.

It’s not the reheating that causes the problem, but the way the rice has been stored before it’s reheated, according to Fiona Hunter, a registered nutritionist and nutritionist for wellbeing brand Healthspan. She explained: “Uncooked rice can contain spores of a bacteria called Bacillus Cereus which can survive when rice is cooked and cause food poisoning. If rice is left standing at room temperature after it’s been cooked, the spores can grow into bacteria which will multiply producing toxins that can cause vomiting or diarrhoea.”

The longer cooked rice is left at room temperature, the more likely it is that the bacteria multiply, so Fiona said it’s vital you get cooked rice into the fridge as soon as possible, within an hour, if you’re planning to reheat it later. She advised: “If you have a large quantity of rice left over it helps to divide it up into smaller portions so that it will cook quicker. Cooked rice should be kept in the fridge for no longer than 24 hours before using and should never be heated more than once.”
