Important Facts About Listeria Infection

Listeria Infection

Listeriosis also known as listeria infection is a medical condition caused by food poisoning; eating foods contaminated with Listeria monocytogenes (L. monocytogenes) cause this fatal disease. It can also be caused by Listeria ivanovii and Listeria grayi.

The causal microorganism L. monocytogenes are found in soil and water and they contaminate food and dairy product when they come in contact with them and they infect the central nervous system causing meningitis, brain abscess, cerebritis, meningoencaphalitis and bacteremia.

This infection mainly affects pregnant women, new born babies, aged individuals and adults with compromised immune systems. Babies can be born with this infection if the mother eats any food contaminated with this microbe during her pregnancy; healthy adults and children can become infected but they rarely become critically ill.

Symptoms of Listeriosis are fever, muscle ache, diarrhea, nausea and dizziness; if the infection enters the nervous systems, symptoms like headache, stiff neck, loss of balance, confusion and convulsions can occur; if it affects a pregnant woman, signs like mild, flu-like illness are seen and it can cause health complications like miscarriage, stillbirth or serious infection of the new born or premature delivery.

A blood test or a spinal fluid test is used to confirm the diagnosis; antibiotics are given to pregnant women to prevent the unborn baby being infected with the disease; these same antibiotics are also given to newborn babies that have the infection.

Antibiotics mostly given are ampicillin and gentamicin because the microorganism is susceptible to these antibiotics.

This disease can be transmitted through oral route when contaminated food is ingested (that is to say it is a food borne disease); the microbe in the food then penetrates the intestinal tract and cause systemic infections.

How to prevent Listeriosis?

Listeria Infection

Listeria monocytogenes are everywhere in the environment and serious precaution is needed not to pick them up or eat food contaminated with them.

These microbes have been found in raw meat, fruit, vegetable, dairy products, soft cheeses, sea foods, unpasteurized milk, unpasteurized pate and post pasteurized milk.

The bacterium is not contagious from person to person but a pregnant woman can transfer the bacteria to her unborn baby.

  • Wash your hands regularly; most especially before and after buying farm foods and after using the bathroom or changing baby’s diaper.
  • Wash fresh fruits and vegetables properly before consumption; wash them under a running water and when you are done chopping them, you can wash your knives and cutting boards properly to disinfect them.
  • Avoid using the same knife and cutting board to cut meat and vegetables.
  • Reheat left over foods properly because unlike most bacteria, Listeria monocytogenes can grow in the refrigerators.
  • All meats should be properly cooked
  • Don’t drink unpasteurized milk or eat foods made with unpasteurized milk.
  • Public food workers should wash their hands with warm soapy water for at least 20 seconds.
  • Don’t eat salads made in store; eat salads made in your home so that you are sure of the cleanliness.
  • Pregnant women should avoid public foods or foods that they don’t know how it was prepared.
