In summer, when the temperature is high and the humidity is high, pathogens become extremely active. Improper storage of food will lead to mildew and deterioration, which not only affects the taste, but also causes gastroenteritis. In particular, there are immeasurable germs in overnight dishes, which can cause food poisoning and even endanger life.

1, green leafy vegetables

The nutritional value of green leafy vegetables comes from freshness, so it is best to eat them in time after cooking, and it is not recommended to eat them overnight. Among many foods, the content of nitrite in green vegetables is relatively high, and it is easy to breed bacteria.

2. Fish and seafood

Fish and seafood are prone to produce protein degradation products overnight, which will damage the liver and kidney function.

3. Fungal food

Mushrooms, fungus, tremella and other fungus foods are not recommended to be eaten after overnight. Tremella itself contains more nitrates. If it is cooked for a long time, the nitrates will be reduced to nitrite under the decomposition of bacteria.

4, bulk pot-stewed

Eat the braised food in bulk as soon as possible after buying it. This kind of cooked food itself is easy to breed bacteria, even if it is put in the refrigerator, it is not safe.

5. Cold salad

The Food and Drug Administration has made special tests on cold salad, and the results show that the prepared cold salad will be contaminated by microorganisms and deteriorate after more than 2 hours in room temperature.

6, overnight mushrooms and tremella

Whether it is wild or cultivated mushrooms or tremella, it contains nitrate. Leaving it for too long can produce nitrite, which will react with amine in the stomach to form ammonium nitrite, which is a first-class carcinogen and easy to cause gastrointestinal discomfort.

7. Half-boiled eggs

Many people like to eat boiled eggs, but this cooking method is not thorough in sterilization. In addition, eggs contain a lot of protein, which is easy to breed bacteria. Half-boiled eggs after overnight are very dangerous and even take away precious lives. Eggs must be cooked thoroughly before eating, not overnight. However, the eggs are cooked completely for the first time 1 time and stored in a low temperature and sealed environment, which can generally be stored for 48 hours.

Tips

For the sake of your own health, the above-mentioned overnight foods must be thrown away, so as not to cause side effects, and then it is too late to regret. Cooked food should not be stored at room temperature for more than 2 hours, and should be refrigerated below 5℃. Leftovers cannot be heated more than once. Different leftovers should be sealed in clean containers, so as to avoid cross-contamination of bacteria.
