We think the fridge can handle anything, but reheating the same container several times is a feast for bacteria

Repeatedly taking cooked food out of the fridge, reheating it, and cooling it again can keep it in the temperature “danger zone” where bacteria multiply faster.

Rice deserves extra caution because Bacillus cereus can survive and cause food poisoning if leftovers are mishandled.

The article also warns that plastic food containers may degrade with repeated cold-and-heat cycles, increasing the chance of chemical migration.

Safe leftover handling matters: cool quickly, store properly, and reheat only what you plan to eat.
