Can you eat rice without reheating?

Yes, you can eat rice without reheating BUT you have to make sure that it has been stored properly otherwise you risk having food poisoning. Uncooked rice can sometimes contain spores from a bacteria known as Bacillus cereus. 

The toxins produced by the bacteria are heat stable to an extent of resisting heat at 126°C for 90 minutes. So, even if the rice is reheated the toxin will not be destroyed and will result in food poisoning.

What is Bacillus cereus?

Bacillus cereus is a gram positive, facultative anaerobic bacteria which has rod shaped cells and can produce heat resistant toxins. B. cereus grows considerably well  in temperature ranges 39ºF (4ºC) to 118ºF (48ºC). It grows optimally within a temperature range of 82ºF (28ºC) to 95ºF (35ºC) and a pH range of 4.9 to 9.3 

Bacillus cereus can be found in vegetation, soil and in the intestinal tracts of mammals and even insects. There are usually 2 types of Bacillus cereus that cause food poisoning; One type causes diarrhea (diarrhoeal-type) this is as a result of the emetic toxin, and the other type causes vomiting (vomiting-type) as a result of the enterotoxin.

What are the symptoms of Bacillus cereus food poisoning?

The symptoms caused by the emetic toxin producing Bacillus cereus are:

  • Vomiting which can result in dehydration
  • Nausea
  • At times it can result in diarrhea
  • Abdominal pain

Symptoms usually within 5 hours after ingestion of contaminated food and can disappear in 6 to 24 hours.

The symptoms associated with the enterotoxin bacteria are:

  • Diarrhea, which can have traces of blood or mucus
  • Nausea,
  • Abdominal pain

Symptoms usually start 8 to 16 hours after ingestion of contaminated food and can disappear in about 12 to 24 hours.

How do you serve rice safely?

In order to ensure that you minimize the risk of food poisoning, ensure that you follow the below guidelines when serving rice:

  • Ensure that you serve rice as soon as it has been cooked.
  • If that is not an option, ensure you cool the riceas fast as possible ideally with an hour
  • Do not refrigerate rice for more than a day until reheating
  • When reheat rice, ensure that it is evenly heated and its steaming all through
  • Never reheat rice more than one time.

How do you properly store leftover rice?

Properly refrigerating leftover rice ensures that you prevent any spores from germinating and toxins that can result in food poisoning from being produced. To properly refrigerate ensure that:

  • You place the leftovers in airtight containers. Make sure that the refrigerator is not crowded with other food items and do not over-stack so that there is good flow of air around the containers and rapid cooling occurs.Leftover rice should not be left at room temperature for more than 2 hours. If so, it’s best to throw it away.
  • Make  sure to refrigerate the rice at temperatures which are below 41ºF (5ºC) to prevent the formation of spores.

You can keep your rice refrigerated for up to 3–4 days

What are some ways to eat cold rice?

You can enjoy cold rice in a number of ways, you just need to ensure that it has been properly stored as highlighted above. Some of the ways are:
