To say that the dirtiest place in the home many people think of the toilet, but in fact, there is another place that is often overlooked by people "large bacterial petri dish", it is the refrigerator, and the refrigerator at home needs to be cleaned regularly.

If you open the refrigerator and find that there is an unpleasant odor, it means that the bacteria in the refrigerator have exceeded the standard, which will contaminate the fresh food and even aggravate the food spoilage.

How did the bacteria in the refrigerator come from, in fact, we usually mistake the refrigerator for a safe, and everything is thrown into the refrigerator.

In fact, some foods in the refrigerator not only can not prolong the shelf life, but will cause the food to spoil faster, once it is bad, it will breed bacteria, pollute the environment in the refrigerator, and endanger health.

So I advise everyone not to put everything in the refrigerator, no matter how big your refrigerator is, don't put these 5 things! The more you put it, the worse it is, it is equivalent to "raising bacteria" in the refrigerator, check it, if there is a refrigerator at home, take it away immediately!

01. Bird's nest

Women often eat bird's nest to nourish their bodies, usually stewed bird's nest can't be eaten and then put in the refrigerator to refrigerate, feeling that it is very convenient to eat and take at any time, but this is actually not right, there are great health risks.

Bird's nest in the refrigerator can hide the risk of Listeria monocytogenes, a very stubborn bacterium that can be called a refrigerator killer because it grows slowly in the refrigerated area (8 - 0°C).

Even if the bird's nest has been stewed, the residual spores will be revived at low temperature, and then slowly multiply and grow, once it is eaten in the stomach, it will be dangerous.

Especially for pregnant women, children, and the elderly with poor resistance, the immunity itself is relatively weak, if the infection with listeria is serious, the consequences are unimaginable, and the stewed bird's nest in the refrigerator may make you feel sick and diarrhea.

This is all because of listeria, so don't ignore it, stewed bird's nest is best to eat as much as you want, if you can't finish eating too much, wait until it is completely cooled and you can put it in a sealed container and put it in the freezer, remember that it is frozen not refrigerated.

02. Tropical fruits

The fruits bought home can not be eaten and then put in the refrigerator, but not all fruits can be put in the refrigerator, especially tropical fruits, the most feared is low temperature, bananas, mangoes, papaya and other tropical fruits in the refrigerator refrigeration will cause the fruit to spoil faster.

Many tropical fruits are not fully ripe after picking from the tree, natural storage will make the fruit's own ethylene completely released, ripening the fruit, but put in the refrigerator, the low temperature environment will inhibit the ethylene, resulting in the appearance of the fruit has rotten, the flesh is not fully ripe.

Bananas can be stored at room temperature for four or five days, but the skin turns black after two days in the refrigerator, which is caused by low-temperature frostbite, which will accelerate the decay of the inside, breeding rotten bacteria and polluting the environment in the refrigerator.

03. Potatoes

Don't put potatoes in the refrigerator, many people don't care that putting them in the refrigerator can reduce the germination of potatoes and produce toxins, but in fact, the starch content of potatoes is very high, and they are placed in the refrigerator.

It will cause the starch to be converted into sugar at an accelerated rate, which will not only affect the taste of potatoes, but also produce acrylamide, which is harmful to the human body, if cooked at high temperature again.

Therefore, it is not recommended to put potatoes in the refrigerator, as long as they are stored in a cool and ventilated place, to avoid moisture causing potatoes to sprout, once the potatoes sprout, do not eat them again, potato sprouts are poisonous.

04. Leave pickled food for too long

Pickles, pickles, bacon and other pickled foods should never be kept in the refrigerator for too long, and it is okay to refrigerate them in a short time, because pickled foods contain nitrates.

The low temperature environment will easily lead to the conversion of nitrate into nitrite, which is a harmful substance to the human body, which will damage the kidneys, pickled food should not be stored in the refrigerator for too long, and it is best not to stock up on homemade kimchi and small pickles.

05. Honey

In fact, honey has no expiration date, as long as it is sealed, it can be stored forever, many people buy home honey in order to extend the shelf life directly in the refrigerator, in fact, this is not right,

It will cause the honey to crystallize at a low temperature, although the properties have not changed, but the taste will be affected, as long as the honey is stored directly at room temperature to avoid direct sunlight, there is no problem.

Not all things can extend the shelf life when placed in the refrigerator, such as the above 5 kinds of food, which is counterproductive when placed in the refrigerator, and it will not achieve the effect of freshness but will breed bacteria.
