In summer, the weather is hot, and the growth and reproduction of bacteria are increasingly active. The so-called "illness from the mouth", when cooking dishes, do you think that there may be "dangerous elements" hidden in the kitchen? What diseases will they cause?
What are the common pathogens in the kitchen?
1. Escherichia coli
● Can cause diseases: sepsis, infective endocarditis, liver abscess, peritonitis, pelvic inflammatory disease and urinary system infection.
● Symptoms after infection: abdominal pain, diarrhea, fever, nausea, dizziness, vomiting and shock.
E. coli is harmless to human body under normal circumstances, but it is easy to cause disease once it is overdosed and human immunity is weak.
● E.coli has low requirements for living conditions, and it will grow in the kitchen where there is a little water or food residue, such as chopping boards, rags and sinks that have not been dried. It is warm and humid in summer, and the growth and reproduction of Escherichia coli is very fast.
● Escherichia coli is not resistant to high temperature. Generally, it can be killed in plain areas by boiling at 100℃ for about 15 minutes to 30 minutes. When the temperature is about 4℃, the growth rate of Escherichia coli slows down; When the temperature is below MINUS 20℃, it enters a dormant state and stops breeding.
2. Listeria
● Can cause diseases: fetal arrest, abortion, meningitis.
● Symptoms after infection: abdominal pain, diarrhea, fever, nausea, dizziness, vomiting and shock.
Listeria is known as the "refrigerator killer" and can still grow at 4℃. Milk, yogurt, eggs, meat, cold drinks and vegetables in the refrigerator may be parasitic.
Low high temperature environment is easy to kill Listeria, and refrigerated food can be sterilized by boiling and heating. In addition, regular cleaning and disinfection of the refrigerator will help to eliminate Listeria.
3. Vibrio parahaemolyticus
● Can cause diseases: gastroenteritis, acute renal failure and wound infection.
● Post-infection symptoms: severe abdominal pain, diarrhea, fever, nausea, dizziness, vomiting and shock may occur.
● Vibrio parahaemolyticus mainly lives in seafood such as fish, shrimp, crab, shellfish and seaweed. Eating food containing this bacterium or being scratched by food containing this bacterium can cause infection.
● Vibrio parahaemolyticus can be killed by heating at high temperature. If sterilized with boiling water, it is recommended to boil for more than 15 minutes.
4. Salmonella
● Can cause diseases: bacteremia, septicemia, gastroenteritis, osteomyelitis, meningitis, vascular implant infection and bone and joint infection.
● Post-infection symptoms: persistent high fever, abdominal pain, diarrhea, nausea, dizziness, vomiting and shock may occur.
Salmonella is easy to appear in kitchen knives, chopping boards, vegetables, fruits, eggs, chicken legs and other foods.
Salmonella can be killed by heating at high temperature.
5. Staphylococcus aureus
● Can cause diseases: meningitis, otitis media, septicemia, pneumonia, folliculitis, wound infection and paronychia.
● Post-infection symptoms: skin pustules, abdominal pain, diarrhea, fever, vomiting, dizziness, etc.
● It is often parasitic on human and animal skin, nasal cavity, throat, stomach and other tissues, and is also found in air and sewage. When eating food contaminated by the bacteria, or when the body wound comes into contact with pollution sources, it can cause infection.
Staphylococcus aureus has a certain tolerance to high temperature, and it can be killed in a high temperature environment above 80℃ for 30 minutes. 70% ethanol can also be used for disinfection.
The doctor reminded that the symptoms caused by these pathogenic bacteria when invading the human body have many similarities, such as diarrhea, abdominal pain, fever, etc. Therefore, once an infection occurs, it is necessary to go to the hospital for examination and test to accurately identify which kind of bacteria is caused, and then take medicine for the symptoms.
