Life-threatening: how to recognize the symptoms of listeriosis and what to do in order not to get infected
Food is regularly recalled in the United States because of the threat of listeria infection and the development of a life-threatening disease like listeriosis. But if many have heard about the risks associated with salmonella, then they do not speak about Listeria so often - although it is an equally dangerous bacterium. How to recognize the symptoms of listeriosis and is it possible to prevent infection?
What is dangerous listeria
Listeria is one of the most dangerous bacteria. It causes serious illness, and in exceptional cases - death, writes Vesti.co.il.
Listeria has many subspecies, the most dangerous is the microbe Listeria monocytogenes. It is found in soil, in the feces of infected animals and in sewage, and can also infect foods.
This bacterium is able to develop and multiply in the refrigerator (at a temperature of + 4 ° C), as well as at a high concentration of salt in the product. For example, in salted or smoked fish. And this despite the fact that most other pathogenic microbes die in such conditions.
Listeria is found in cold smoked fish and meat products or in those that have not undergone sufficient heat treatment. In addition, it may be present in unpasteurized dairy products, in hummus and poorly washed vegetables.
Even if the dish was cooked correctly, it can become infected from a cutting board, which was poorly washed after working with vegetables or raw meat.
Symptoms of infection
The incubation period lasts from 3 days to 2 months after eating contaminated food.
Initially, the symptoms resemble the flu (fever, fatigue, nausea, vomiting, diarrhea). In severe cases, the microbe enters the bloodstream, causing sepsis, meningitis (especially in young children), miscarriages and premature births in pregnant women, pneumonia and pericarditis.
How to avoid infection
- In order not to become infected, it is necessary to cook meat and fish so that the temperature in the center of the piece is not lower than 72 ° С.
- You should not buy products in dubious places. This is especially true for meat, fish, unpasteurized milk.
- After cooking, be sure to wash your hands with soap.
- Before eating fruits and vegetables, wipe them with a clean cloth and avoid foods that have stood in the refrigerator for a long time or have expired.
How is listeriosis treated?
Listeriosis is treated with antibiotics, in severe cases they are administered intravenously in a hospital setting. In most cases, antibiotics of the penicillin group (penicillin, ampicillin) are used, with an allergy to penicillin it is replaced with the drug resprim.
