You've probably heard of a time when you suddenly get a stomach ache, a fever, and vomiting after eating a meal? Most of the time, we simply call this "food poisoning." However, there are some foodborne infections that can be a little dangerous, especially for some people. Listeriosis is one of them. Let's talk about this in a little more detail today, because it's very important for everyone to know about it.
What is Listeriosis? Simply put...
Simply put, Listeriosis is a type of food poisoning . It is caused by a type of bacteria called Listeria monocytogenes. Many people also call this bacterial infection "Listeria" for short.
Now, most people who get Listeria have mild symptoms like fever, headache, diarrhea, or vomiting. However, if you have a weakened immune system or are over 65 , you are at greater risk for life-threatening complications. Especially if you are a pregnant woman , you can pass the infection to your baby during pregnancy, during delivery, or during delivery. Doctors call this vertical transmission. This can lead to miscarriages or serious, lifelong health problems for your baby. So it is important to be aware of this.
What are the symptoms of Listeriosis?
Listeriosis symptoms may include:
- Having a fever
- Feeling cold (Chills)
- Headache
- Stomach upset (diarrhea)
- Nausea and vomiting
- Body pain, joint pain
- Feeling tired
Not everyone will experience all of these symptoms. Sometimes, only one or two may occur.
However, if this Listeria infection spreads beyond your digestive system to other parts of your body (this is called invasive listeriosis), more serious symptoms can occur. These include:
- Confusion, confusion
- Loss of balance
- Stiff neck
- Seizures
If you experience such severe symptoms, you should definitely seek medical advice immediately .
How long does it take for the bacteria to enter the body before the disease appears?
Typically, symptoms of listeriosis begin to appear within a few days to two weeks after eating food contaminated with this bacteria. However, keep in mind that if you are a pregnant mother, you may only have mild symptoms, or no symptoms at all . However, it is still possible to pass the infection to your baby.
What are the main causes of Listeriosis?
The main cause of this is a bacteria called `(Listeria monocytogenes). This is contracted when we eat food or drink that has been contaminated with the bacteria . If you are pregnant and you get a listeria infection, it can be passed on to your baby during pregnancy or during delivery.
What types of foods are most likely to contain Listeria bacteria?
These foods are most likely to contain Listeria bacteria, so you should be especially careful when consuming them:
- Processed meats, for example `(Deli meats)`, `(cold cuts)` and `(hot dogs)`.
- Pâté (a spread made from minced meat) and meat spreads.
- Cold-smoked fish, for example lox.
- Some soft cheeses, such as Brie, Camembert, and queso fresco.
- Unpasteurized dairy products . That means things like milk, cheese, and ice cream that haven't been pasteurized (a process called pasteurization kills germs).
- Unpasteurized fruit juice, for example apple cider.
- Eating raw, poorly washed fruits and vegetables (especially fruits like watermelon).
- Sprouts.
- Raw sushi is made from raw fish.
When it comes to these foods, pregnant mothers, the elderly, and those with weakened immune systems should be especially careful.
Is Listeriosis a contagious disease?
No. Listeria infections are not contagious . This means you cannot spread the disease to those around you. This is important because some people may be afraid of this.
Who is most at risk if they develop this disease?
The following people are at higher risk of becoming seriously ill or dying from Listeriosis:
- For pregnant women
- For those over 65 years of age
- For those who have a weakened immune system , either due to a medical condition or due to taking immunosuppressive medications.
If you fall into these categories, you should think twice about food safety.
What are the dangerous complications that can occur due to Listeriosis?
If the Listeria bacteria spreads from your intestines to other parts of your body, it can cause serious complications . Some of them include:
- Infection of your heart (called ``endocarditis''), infection of your bones (``osteomyelitis''), or infection of the membrane surrounding your abdominal organs (``peritonitis'').
- Infection of your brain and spinal cord (encephalitis), or infection of the membranes covering them (meningitis).
- Miscarriage, stillbirth, or preterm birth.
- Pneumonia.
- Sepsis - This is a severe response of the body to an infection, which can damage organs.
- Septicemia - This is when bacteria multiply in the blood and spread to other parts of the body.
- Urinary tract infections.
- Even death can occur .
Importantly, if someone is born with Listeriosis, or if the infection spreads to the brain or causes sepsis, long-term health problems can occur. For example:
* Developmental delays or differences
* Blindness
* Organ damage or failure
* Paralysis
* Seizures
Therefore, this is not something that can be easily imagined.
How do you know for sure if you have Listeriosis?
There's no way to know for sure if you have Listeriosis without getting tested . Many people don't get tested unless their symptoms are severe.
However, a doctor may suspect that you may have listeriosis based on your symptoms and any foods you have recently eaten that may have been contaminated with the bacteria. They can confirm this by testing your blood , cerebrospinal fluid, or amniotic fluid if you are pregnant, for signs of the bacteria.
There may be other tests:
- Performing a blood culture.
- If you are pregnant, taking and testing tissue from the placenta after the baby is born.
- If you have symptoms related to the nervous system (e.g., seizures, confusion), a brain CT scan or MRI may be performed.
How is Listeriosis treated?
Listeriosis is treated with antibiotics . Examples include sulfamethoxazole and ampicillin. It is important to take the medication exactly as prescribed by your doctor, for the full duration of the medication , and do not stop taking it even if you feel better. If you do not take the medication properly, the infection can come back.
However, if you have mild symptoms, are not pregnant, and are not at risk for serious complications , you may not need treatment. This will be determined by your doctor.
When should you see a doctor?
If you are in this situation, you should definitely see a doctor:
- If you are pregnant, over 65, or have a weakened immune system and you have symptoms of a Listeria infection.
- If a food or drink you've recently eaten has been recalled due to Listeria , be very careful, especially if you're pregnant.
- If your little one has symptoms of Listeriosis .
- If your symptoms do not improve after a few days of starting antibiotics.
Ask your doctor how to use the medications prescribed by your doctor and what to do if you miss a dose.
What can we do to protect ourselves from Listeriosis?
You can reduce your risk of getting a Listeria infection by following food safety guidelines. Here are some of them:
- Avoid unpasteurized dairy products and fruit juices . This includes milk, cheese, and ice cream.
- Wash your hands and food preparation surfaces (e.g. cutting boards, knives) thoroughly before and after preparing food.
- Clean raw fruits and vegetables thoroughly under running water, using a brush if necessary .
- Cook hot dogs, egg dishes, and seafood thoroughly until the internal temperature reaches 74 degrees Celsius (165 degrees Fahrenheit) .
- If you are pregnant , avoid refrigerated pâtés, deli spreads, or meat spreads from the meat counter at the supermarket. If you eat lunch meat, make sure it is well-cooked .
- If you spill something in your refrigerator, especially meat juices, clean it up right away .
Does cooking kill Listeria bacteria?
Yes . When foods are heated to the proper temperature, that is, cooked thoroughly, the Listeria bacteria are destroyed . Therefore, it is very important to cook food thoroughly.
Does Listeriosis get better on its own?
Yes, if your immune system is strong and you are not pregnant , you can usually recover without treatment in two to three days.
However, if you are pregnant or have any risk factors for serious illness , you should definitely see a doctor immediately. Because it is said that about 1 in 6 people who get invasive listeriosis will die. So don't take this lightly.
Is there anything I can do to get relief when I have symptoms?
When you have symptoms of Listeriosis, you can do these things to manage them:
- Have a good rest .
- Drink plenty of fluids .
- Avoid drinking alcohol and caffeinated beverages , as they can increase bowel movements.
- Over-the-counter medications can help relieve some symptoms. However, if you are giving medication to children, it is important to check with a doctor to make sure that the medication is safe for them .
Finally, the most important things you need to remember
For most people, food poisoning is just a mild illness that lasts for a day or two. However, some bacteria, like Listeria, can cause serious health problems . If you have a weakened immune system or are pregnant, be aware of food recalls and talk to your doctor about how to protect yourself from contaminated food. Staying healthy is the most important thing!
