How many days can food stay overnight?

How long a dish can stay overnight is generally determined by the dish. Generally, cooked dishes are best not to stay overnight. Because there are many nitrates in vegetables, they may be converted into toxic nitrite due to the activities of bacteria during storage. Although put in the refrigerator for one night, the amount of this nitrite is far from the level of food poisoning, but some are not good for the stomach. Eating it the next day will lead to diarrhea, and the nitrite in cooked food will exceed the standard, leading to abdominal pain, diarrhea and poisoning. It is best not to exceed 24 hours.

Do not freeze for more than two weeks.

Generally, when storing food, if it is well sealed, avoid foods that are easy to produce nitrite, such as stir-frying, scrambled eggs with leeks, braised pork and braised crucian carp. And pay attention to adjust the temperature when freezing. If you eat it after heating, you should first check whether it is spoiled. If it smells, don't be embarrassed and throw it away at once.

Cooked food and raw food should be separated

Many people put cooked vegetables and raw vegetables together and put them in the refrigerator, which is actually wrong. Because raw food has not been sterilized at high temperature, it is easy to produce bacteria, which will lead to cross-infection of raw and cooked food. It can cause diarrhea and poisoning after eating. So when preserving overnight dishes, be sure to separate cooked food from raw food.
