In November 017, 39 weeks of pregnancy, Xiao Zhou (pseudonym) had a feverish high fever for several days, and what Xiao Zhou (a pseudonym) did not think was that this sudden high fever would have been born for two months. The baby's life, and Xiao Zhou himself almost left the world. The culprit in causing this tragedy was a piece of frozen meat that was taken out of the refrigerator. Why is a piece of frozen meat going to life? How can the food in the refrigerator be stored and placed to ensure safety? How is a small Listeria killed? How should it be kept away from Listeria in life? On April 17th, at 21:48, CCTV's financial channel "Workplace Health Class" will invite Li Taisheng, the chief physician of the Department of Infectious Diseases of Peking Union Medical College Hospital, and Cao Yu, the deputy chief physician, to talk about the mysterious Listeria. Killer in the refrigerator: Listeria In 1926, the scientist Murray first discovered a strange bacterium in the dead rabbit. This bacterium was later known as the "fridge killer" Listeria. Listeria is widely found in nature, including soil, water, insects, plants, vegetables, fish, birds, wild animals, poultry, etc. It has been found in the world. There are ten strains of Listeria in the world, but it is true. Only Listeria monocytogenes can cause human diseases. Listeria can enter the body through contact with the eyes and damaged skin, but in most cases it is eaten. Its main vector is food, which is one of the most deadly foodborne pathogens. Most notably, Listeria is an anaerobic bacterium. Under anaerobic conditions, Listeria invasiveness is more than 100 times higher than normal. Known as the "fridge killer", the main reason is that Listeria can survive at 2~42 °C, which is one of the main pathogens of frozen food threatening human health. In addition, Listeria is highly adaptable, and it has the ability to resist dryness and high salt tolerance, and can adapt to acidic and alkaline conditions. The presence of Listeria monocytogenes in food can cause human life safety. Listeria contamination risk in the following foods: ◆ cheese made from unpasteurized raw milk; ◆ Unsterilized mayonnaise; ◆ Sandwiches that are prepared in advance and stored for a long time; ◆Uncooked bean sprouts; ◆A salad bag purchased outside or a salad prepared in advance. Listeria is an important public health problem. Listeria monocytogenes has been listed as a legal infectious disease surveillance project in the United States, Canada, Australia, South Africa and the European Union. Be alert to these symptoms, be careful with Listeria to find you The early symptoms of Listeria infection are not obvious. Some symptoms after infection are similar to those of a cold. Infected patients usually develop diarrhea and fever at first, and severe fever, neck stiffness, confusion, muscle weakness or vomiting can occur in a few days or weeks. After eating foods with Listeria, the symptoms can appear in 3 days, usually around 1 to 3 weeks, but some people will not develop symptoms 2 months after eating contaminated food. But Listeria is more dangerous because it can enter the lymphatic system and invade the brain through the bloodstream. Encephalitis and meningitis are the main causes of death in Listeria patients. Especially for pregnant women, with the pregnancy process, the pregnant woman's cell-regulated immune response is inhibited, making her body more susceptible to Listeria infection. Pregnant women will also pass the germs to the fetus, newborn babies, causing miscarriage, fetal death, or causing sepsis or meningitis in newborn babies. Consider the presence of Listeria when the following symptoms occur: If you have any of the symptoms listed above, and you are pregnant, older, have a serious physical illness, or are using drugs that can weaken your immune system, you should go to the hospital for further testing. If your newborn has the following conditions, you should contact your doctor or nurse: ◠There is fever or any other symptoms mentioned above ◠Behaves differently than usual, such as eating less, breathing faster or looking more sleepy than usual Be careful, you may be the target of Listeria! Although Listeria is widely present in our lives, it is not too worrying. Only a subset of people are more susceptible to Listeria. Listeria infection can cause minor or serious problems. It is usually not severe in healthy people, but it is more dangerous in pregnant women than in non-pregnant people. Which populations are susceptible to Listeria and are at risk of serious problems? ◠pregnant women; ◠newborns; ◠older people; ◠People with AIDS, cancer, diabetes or other serious physical illnesses; ◠People who have received organ transplants or stem cell transplants; ◠People who use drugs that make it difficult for the body to fight infection. How can high-risk populations prevent Listeria infection? The risk of infection with Listeria can be reduced by paying attention to food safety. Tips include: ◠Avoid ingesting unpasteurized milk and cheese, and foods made with them; ◠Wash plenty of fruits and vegetables before eating; ◠Be sure to be cooked when cooking meat and seafood; ◠To achieve the degree of hardening of the egg yolk when cooking eggs; ◠Hand, knife and chopping board should be cleaned after contact with raw food. Listeria has the ability to resist dryness and high salt tolerance, and its vitality is relatively tenacious. But Listeria is not heat-resistant, and it can be dealt with by simple measures such as pasteurization and cooking. Is there a check for Listeria? There are currently several different related checks. Choose according to the symptoms and whether you are pregnant or have other physical illnesses. Specific checks include: ◠blood test; ◠lumbar puncture; ◠check stools; ◠Brain imaging examination. Pregnant women, newborns, and people with severe Listeria infections are treated with antibiotics, which are usually given to patients via intravenous infusion, and patients with very severe conditions may require hospitalization. Patients with digestive system infection with Listeria but otherwise healthy are usually not required to be treated, and the infection usually resolves itself after approximately 2 days. Infection treatment of the brain is more difficult than infection in other areas. The symptoms of Listeria monocytogenes in the brain may progress faster, and are more likely to be directly life-threatening and more serious. Timely and effective support and symptomatic treatment are needed. Some serious conditions require treatment in the intensive care unit. In addition, the choice of drugs for brain infections is also more difficult. Bacterial infections are often treated with antibiotics, but the types of antibiotics that can enter the brain are limited, and it is sometimes difficult to know at the first time what bacteria are causing the infection. In addition, bacteria may also be resistant, which increases the difficulty of drug treatment. Each type of encephalitis has a different severity, but in any case, encephalitis itself is a relatively serious disease. Even after effective treatment, patients may still have sequelae such as ataxia, aphasia, eyeball paralysis, and limb paralysis after treatment. High-power electronic power devices are repotted into an integrated module according to a certain combination of functions.
