Listeria monocytogenes infection in pregnant women causes sepsis
Fetal shock of prematurity
Xiaomei (pseudonym), a pregnant woman in Yueqing, Wenzhou, Zhejiang, drank a glass of fresh milk that had been opened in the refrigerator when she was 27 weeks pregnant.
But 7 days after drinking milk, Xiaomei suddenly began to have a low-grade fever, and the blood routine and CRP indicators in a local municipal hospital increased significantly, and the doctor prescribed "cephalosporin", Xiaomei's body temperature returned to normal after taking it, and the blood routine and CRP indicators gradually declined.
Finally, on the 21st day after drinking that glass of milk, Xiaomei's body temperature suddenly burned to 39.2 °C, premature rupture of membranes, and fetal intrauterine hypoxia urgently went to the obstetrics emergency cesarean section of the Second Affiliated Hospital of Wenzhou Medical University in the middle of the night.
The baby developed septic shock shortly after birth, and the blood routine showed abnormally high leukocytes and a leukemia-like reaction.
After treatment, the baby's condition gradually improved. After 2 days, Xiaomei's blood culture report showed "Listeria monocytogenes" infection, and placental biopsy showed "acute chorioamnionitis and umbilical corditis", confirming intrauterine listeria infection. Fortunately, after the mother and son underwent rescue treatment in the hospital, Xiaomei was discharged from the hospital on June 12, and the infection of the premature baby was completely controlled on June 13.
The case fatality rate of neonatal infections is as high as 30% to 70%
Why is Listeria so scary?
Listeria monocytogenes is very common in our lives and can be found in most foods, soil, plants, animal feed, and human and animal feces.
Listeria monocytogenes is most likely to be found in raw milk and its products, ice cream, raw fruits and vegetables, meat and meat products, cold cooked foods, raw foods, smoked seafood, etc.
Many people think that the refrigerator is a "safe", but it has little effect on Listeria monocytogenes, because its viability is very strong, in the environment below 4 °C, the vast majority of bacteria will slow down the growth rate, but Listeria can still grow and multiply in the refrigerated environment of 0~4 °C, and can survive for 1 year at -20 °C, and the refrigerated ready-to-eat food with a long shelf life (more than five days) is a high-risk food for infection with Listeria monocytogenes.

Patients infected with Listeria monocytogenes usually have symptoms such as nausea, vomiting, diarrhea, fever, headache, and muscle pain 3~70 days after eating contaminated food, and severe cases of infection may also develop septicemia and meningitis. Especially after pregnant women are infected, bacteria can infect the fetus through the placenta, which may cause miscarriage, stillbirth or premature birth, septicemia and neonatal meningitis and other serious consequences, and the mortality rate of neonatal infection is as high as 30%~70%.

How can I avoid getting Listeria monocytogenes?
- Keep it clean
Keep your hands clean, and in addition to washing your hands before and after meals, before and after using the toilet, you should also pay attention to hand hygiene before and during cooking. Kitchen utensils should be kept clean, and special attention should be paid to the hygiene of dishes, chopsticks, chopstick boxes, knives, cutting boards, and rags to prevent them from becoming a source of pollution.
2. Separate raw and cooked
During the cooking process, raw and cooked foods should be separated. "cooked" here refers to foods that are eaten directly after being cut, such as vegetable salad, cold cucumber, jellyfish skin, beef in sauce, etc.; "Raw" refers to food that has been subjected to heat treatment after it has been cut. Separating raw and cooked food not only means that they should not touch each other, but also that the cutting boards, knives, and utensils used should also be separated.
3. Boiled Toru
Listeria monocytogenes is most afraid of high temperatures, and food can be killed after 5~20 minutes when fully cooked or heated to more than 60°C. Therefore, raw foods should be cooked thoroughly, especially meat, poultry, eggs and seafood.
4. Keep food at a safe temperature
Cooked food is not recommended if stored at room temperature for more than 2 hours. All cooked and perishable foods should be refrigerated (below 5°C) in a timely manner. Food should not be stored in the refrigerator for too long. Do not thaw frozen food at room temperature. It is best thawed in the microwave, refrigerator or clean running water. When using a microwave oven, ensure sufficient heating time to bring the core temperature of the food to above 60°C.
5. Use safe water and raw materials
Do not drink unclean water or unboiled tap water, and choose foods that have been safely processed. For pregnant women, it is more strict, do not eat food that has been left in the refrigerator for a long time, do not drink unpasteurized or unsealed milk in the refrigerator, and do not eat raw and cold food.
