Does Cooked Rice Go Bad?

by Lauren Corona

Rice comes in all sorts of varieties -- from arborio to basmati -- but all of them can go bad when cooked, if not stored properly or kept for too long. Spores of a bacteria called Bacillus cereus can grow and multiply in cooked rice, potentially causing food poisoning.

Cooked Rice Safety

Rice should be cooled and put into the refrigerator as soon as possible after cooking it. Ideally, it should go in the fridge within an hour of being cooked, but up to four hours is acceptable. The longer it stays at room temperature, the more time bacteria has to multiply. Refrigeration slows the bacteria's rate of reproduction. It can be kept in the fridge for up to three days before going bad, but eating leftovers the next day is preferable. When reheating your rice, ensure it's piping hot all through, and never reheat it more than once.
