The refrigerator is actually the biggest place for bacteria.

Recently, Ms. Li and her family who lived in Dongfeng Middle Road had suffered from different degrees of abdominal pain and diarrhea after eating frozen frozen fish in the refrigerator.

According to Ms. Li, due to the recent hot weather, in order to prevent food from spoiling, she stuffed all the meat, fish, fruits and vegetables bought from the vegetable market into the refrigerator.

What she can’t figure out is, since the refrigerator can keep fresh, why do you have problems after eating?

If the food in the refrigerator is improperly stored, it will increase the chance of food deterioration and cross-contamination, causing “food poisoning in the refrigerator.”

  ”Fridge food poisoning” can cause meningitis. From June to August every year, it is the season of acute asthma. In fact, the crisis is hidden in the refrigerator we use every day.

Director Wang Zhengwei of the hospital emergency department told the New Express reporter that the bacteria were particularly active during the hot summer months. They often accompanied our hands and bought the food into the refrigerator.

The temperature of the refrigerator freezer is generally between 0 ° C and 7 ° C. This temperature has a significant inhibitory effect on the reproduction of most bacteria, which can supplement the food deterioration time, but will not kill the bacteria.

Among them, some bacteria that are chilled in cold environments, such as Escherichia coli, Salmonella typhi, Staphylococcus aureus, are still active in the refrigerator, and they continue to multiply and accelerate food spoilage.

In addition, raw food, even if added to the refrigerator will continue to metabolize, producing toxic metabolites.

  “A lot of families buy a lot of food, no matter how raw food is cooked, it’s done in the refrigerator.

They don’t know that the bacteria on the food may be crossing each other at the same time.

After taking out the bacteria-containing food from the refrigerator, if it is not thoroughly cooked and sterilized, it will cause nausea, vomiting, abdominal pain, diarrhea, dizziness and other symptoms after eating. This is what people do not know about ‘refrigerator food poisoning’.

He Qing, deputy director of the Department of Gastroenterology, Clinical Nutrition Department.

  She also pointed out that “latent” in the refrigerator is also a very powerful psychrophilic bacteria – Listeria, which is mildly diarrhea, stuffy nose, fatigue, and is often mistaken for a cold.

For the elderly with weak resistance, children and immunodeficiency people, diarrhea may also cause meningitis.

  Fresh-keeping time: Two days of leafy vegetables for two weeks. “Put fresh food and vegetables into the refrigerator. After a few days, we will find that the color is light, water loss, nutrient loss, and bad taste.

This shows that the refrigerator is time-sensitive to the preservation of food.

He Qing pointed out that the storage time of leafy vegetables in the refrigerator should not exceed 2 days; the storage time of fruits should not exceed 5 days; the storage of fresh eggs should not exceed 2 weeks.

However, absolutely frozen foods should not be stored in the freezer for more than one month.

  There is a trick to prevent “bacteria”.

Do not clean the food before entering the box. People who are used to cleaning the food are used to cleaning the food. Even after cleaning and cleaning, they are put into the refrigerator. In fact, the surface of the fruits and vegetables has its own anti-bacterial “protective film”, which will protect the film.After washing off, it will help bacteria invade food and accelerate food spoilage.

If you find that the fruits and vegetables, eggs and other skins are dirty, you can wipe them with a cloth, put on the fresh-keeping bags and put them in the refrigerator.


Tropical fruits and vegetables should not be placed in the refrigerator, fruits and vegetables, mangoes, bananas, lemons, lychees and other tropical fruits should not be placed in the refrigerator, otherwise it will be “frozen” to accelerate its deterioration.

The most common fruit watermelon in summer, it is best to buy it now. After taking it out of the refrigerator, it is best to remove the melon meat exposed to the air and eat it.


Raw and cooked foods are stored separately. After the cooked meat products such as roast chicken are opened, do not put them in the refrigerator directly. This will not only pollute the refrigerator environment, but also accelerate the deterioration and can be placed in the crisper.

In addition, raw fish can also be placed in a crisper and stored in the freezer of the refrigerator.


The refrigerator food is thoroughly cooked and then eaten under normal circumstances, heating for more than 5 minutes, the pathogenic bacteria on the food can basically kill.


Boxed, bottled food after eating two times to finish listening, bottled, canned, Tetra Piano, vacuum packed beverages, dairy products, meat, poultry, eggs, it is best to eat immediately after opening.

If you store the rest of the refrigerator, you should eat it in two places.

Pasta bags should not be sealed, such as steamed buns, snacks, etc., should be filled in the food bag and then put into the refrigerator freezer, but the mouth of the bag is not allowed to die.
Because in the sealed environment, anaerobic bacteria will multiply, and it is easy to breed bacteria and other bacteria, causing it to become odorous and deteriorate.
