In the hot summer, the refrigerator is our good partner.
What cold porridge cold noodles, leftovers, fruit milk
a brain
The refrigerator is used to keep food fresh, but it is not a safe! If you use it improperly, you will not be able to keep it fresh, but it will bring us a variety of 'fridge diseases'.
The so-called 'refrigerator disease' refers to the fact that people eat food stored in the refrigerator, causing adverse reactions to diarrhea or gastrointestinal diseases, mainly through contaminated food, water, and through the digestive tract. People can also be infected through contact. Common sources of pollution such as E. coli, Staphylococcus aureus, etc., are most likely to contaminate fruits, vegetables, fish and dairy products.
I will give you a glimpse of the pathogens in the refrigerator.
1, psychrophilic bacteria
Psychrophilic bacteria have strong anti-freezing ability, and more typical are Listeria, Yersinia, etc. These are pathogenic bacteria.
Listeria likes to hide in milk, so it is not safe to put half of the milk in the refrigerator. Although Listeria is rare, once infected, it causes abdominal pain, diarrhea, fever, etc., and the nervous system Disease and sepsis, etc.
2. The raw pork in the refrigerator is a hotbed of Yersinia. The infection with Yersinia is acute gastroenteritis, enterocolitis.
2, mesophilic bacteria
4. Thermophilic bacteria are usually brought into the refrigerator by foods that infect bacteria. Common mesophilic bacteria are Salmonella, Escherichia coli, Shigella and Staphylococcus aureus.
Salmonella is commonly found in eggs, poultry and meat products. It is the most common pathogen. The egg shell has a very high rate of growth and is the main growth site for Salmonella. Therefore, eggs should be stored separately. Infection with Salmonella can cause diarrhea. , food poisoning, even encephalitis.
Shigella is mainly found in vegetables and fruits, and is the main pathogen causing dysentery.
3, mold
Mold is mainly found on taro and bread. The temperature in the refrigerator compartment is very suitable for mold growth.
Therefore, don't think that food enters the refrigerator, there is no worries. The common refrigerating temperature for storing food in the refrigerator is 4 to 8 ° C. This temperature has a certain inhibitory effect on most bacteria, which can delay the deterioration of food, but will not kill. bacterial.
Some of the psychrophilic bacteria are still active in the refrigerator. They continue to multiply and accelerate the deterioration of the food. These bacteria produce a lot of metabolic gases during the process of growth and metabolism. Mixing together will make the refrigerator produce an unpleasant smell.
3. If you eat foods that are infected with such bacteria, you may have acute gastroenteritis, fever, diarrhea, meningitis, and sepsis.
In the freezer of the refrigerator, although the stored food has a better preservation effect, it does not mean complete sterilization, and some bacteria with strong anti-freezing ability will survive. So, from another point of view, if the refrigerator is not often Disinfection, it will become a 'hotbed' of some bacteria.
The following disease control Jun introduces you to several methods of disinfecting the refrigerator. It is recommended that you should disinfect it after you go home.
note
Before disinfecting the refrigerator, turn off the power, stop the refrigerator, and then take out the stored food, defrosting the inside of the refrigerator and wiping all parts and accessories of the refrigerator, and then disinfecting.
Disinfection method one or two is available
Wipe with 75% alcohol or acetic acid solution or 0.1% benzalkonium chloride solution with a soft cloth. Close the box for 15-30 minutes. Wipe the disinfection area with water and dry.
Spray with 0.05%-0.1% peracetic acid solution, close the door for 20-30 minutes. Then, scrub the disinfection part with water and dry it. The concentration of peracetic acid solution is too corrosive to the metal, so it must be Pay special attention to the concentration.
Spray with 2% alkaline glutaraldehyde aqueous solution, close the door for 30 minutes. Then, scrub the disinfection part with water and dry it. The glutaraldehyde disinfection is better under alkaline conditions. It should be added 0.3% before use. Sodium bicarbonate is activated, but the stability of alkaline glutaraldehyde is poor, and it is best to use it now.
In addition to cleaning and disinfecting the internal parts of the refrigerator, it is necessary to pay attention to the drip tank inside the refrigerator, the separator groove and the sealing strip and other dead angles for spray disinfection. After cleaning, a small box of soda can be placed in the refrigerator to keep the refrigerator. The smell is refreshing.
Due to the high frequency of domestic refrigerators, the refrigerator should be cleaned, sterilized and disinfected at least once a month.
