what & lt; Refrigerator disease;?
refrigerator neck refers to the adverse reactions of diarrhea or gastrointestinal diseases caused by eating food stored in the refrigerator. Improper consumption of food taken from the refrigerator may cause various kinds of refrigerator neck, such as refrigerator headache, refrigerator pneumonia, refrigerator gastritis, refrigerator enteritis, etc. Although the low temperature in the refrigerator can inhibit the reproduction of most bacteria, some psychrophilic molds can continue to grow. Now it is generally believed that a kind of Yersinia enterocolitis may be related to the popularity of refrigerators. Yersinia widely exists in pigs, dogs, cats, cattle, horses, sheep, rabbits, pigeons and other animals, and can survive for a long time.
the transmission route of refrigerator disease is
, which is mainly transmitted through the digestive tract through contaminated food and water. People can also be infected through contact. Yersinia could still grow at – 4 ℃. Most likely to pollute fruits, vegetables, fish and dairy products. If these foods are not fully heated, it is easy to cause refrigerator enteritis, resulting in abdominal pain, diarrhea, vomiting and other diseases. Therefore, enterocolitis caused by this bacterium may be related to the widespread use of refrigerators. The main symptoms are abdominal pain, diarrhea and fever. Diarrhea is mostly watery without mucus.
what are the hazards of long-term consumption of refrigerator food
1, refrigerator pneumonia
if the refrigerator is not often scrubbed, it is easy to breed fungi in the exhaust port and evaporator of the refrigerator. These fungi have strong cold resistance, can grow and reproduce at low temperature in the refrigerator, and disperse into the air with dust. People with allergic constitution and children who inhale this kind of air with bacteria are very likely to have cough, chest pain, chills, fever, chest tightness, asthma and other symptoms, which is clinically known as refrigerator pneumonia.
2, refrigerator headache
the food temperature just taken out of the refrigerator freezer in summer is generally below – 6 ℃, while the oral temperature is about 37 ℃. If you eat fast, it can stimulate oral mucosa, reflexively cause head vasospasm, and produce a series of symptoms such as dizziness, headache and nausea.
3, refrigerator enteritis
although the low temperature in the refrigerator can inhibit the reproduction of most bacteria, some psychrophilic molds can continue to grow. For example, Yersinia can still multiply in a low temperature environment of about 0 ℃. When unheated food enters the colon, the colon mucosa will fall off and swell, causing extensive inflammation and causing abdominal pain, diarrhea and vomiting. The disease is called Yersinia colitis.
4, refrigerator gastritis
in summer, if people eat more cold food in the refrigerator, after the gastrointestinal tract is stimulated by strong low temperature, the blood vessels will shrink suddenly, the blood flow will decrease, and the gastrointestinal digestive juice will stop secreting, which leads to physiological dysfunction and induce upper abdominal paroxysmal colic and vomiting, which is called refrigerator gastritis.
how to prevent & lt; Refrigerator disease & quot;
1, cold food should not be eaten immediately:
foods taken out of the refrigerator and can not be reheated should be stored at room temperature for a period of time before eating. Cold drinks and food in the refrigerator should not be taken out when the weather is hot, and should not be eaten too much when you are sweating and thirsty. Don’t ice watermelon for more than two hours: it’s better to buy and eat watermelon now. If it needs cold treatment, it should not be placed in the refrigerator for more than two hours, which can not only prevent heatstroke, but also not hurt the spleen and stomach. People with weak spleen and stomach and poor digestive ability had better eat less or no cold drinks and food, especially children and the elderly.
2, food placement:
the food stored in the refrigerator must be raw and cooked separately, to prevent cross contamination, food quality should be checked before eating. Some foods need to be treated before they are put into the refrigerator. For example, the rotten leaves of vegetables should be removed first, and the viscera and scales of fish should be removed first; Hot food should be fully cooled before being put into the box; The food should be packed with food bags or fresh paper or put into airtight containers to prevent dry consumption and cross taste of food; Do not freeze thawed food; Raw and cooked food should not be mixed together to reduce food pollution; Leftovers should be placed separately to avoid pollution. Food should not be piled up and stored, and proper space should be left between them. When you take food out of the refrigerator, take as much as you need. Don’t put it in again. Don’t store too much food in the refrigerator. There should be spaces between things to facilitate air convection. If large pieces of food are stored, they should be cut and stored.
3, food not suitable for refrigerated in refrigerator:
cucumber, green pepper, eggplant and other vegetables in the refrigerator for a long time, there will be frostbite& mdash;& mdash; It turns black, soft and tasteless. Banana, pitaya, mango, litchi, longan, papaya, rambutan and other tropical fruits should not be refrigerated, otherwise the pulp will turn black and taste. Potatoes, sweet potatoes, radishes, etc. are not easy to rot because of their thick skin. They do not need to be stored in the refrigerator. They can be stored indoors in a cool and dry place.
4, storage time is limited:
to master the storage time of different foods, select the appropriate storage area. The time of storing food in refrigerator should not be too long, the refrigeration time of raw meat should not exceed 2 days, and that of fruits and vegetables should not exceed 5 days. Do not refrigerate pumpkin, radish, onion, potato, banana, canned food, etc. In order not to store refrigerated food more than the specified time, it is better to hang a Book outside the refrigerator to record the storage time.
5, refrigerators should be placed in a cool, dry environment:
that is, away from all kinds of heat sources, such as gas stoves, etc; Avoid direct sunlight; Don’t put it in a wet place, otherwise it is easy to cause failure and rust of metal parts. In addition, the refrigerator should be 10 cm away from the wall. When using the refrigerator, we should prevent the mechanical failure and power failure, and keep the temperature in the refrigerator at about – 6 ~ 8 ℃. Finally, we should often check the electrical equipment in the refrigerator and the specified temperature. In case of power failure, electric leakage, mechanical failure or insufficient temperature, we should repair it in time.
6, regular disinfection is necessary:
refrigerator to keep clean, regular cleaning, especially the exhaust port and evaporator. In summer, the refrigerator should be cleaned and disinfected once a week. 0.5% bleaching powder can be used to scrub the refrigerator. Special attention should be paid to scrub the box seams, corners and shelves, and then wipe them with a clean wet cloth. Garlic can also be placed in the exhaust port and the evaporator under the refrigerator for sterilization.
