Listeriosis is a condition caused by Listeria monocytogenes bacteria. These bacteria are widespread in nature and can be found in the soil, water and in many animals. People most often get infected with Listeria after eating food that is contaminated with the bacteria.
Symptoms of listeriosis resemble those of the flu and may include fever, chills, headache, feeling unwell, muscle pain and diarrhoea. If the bacteria infect the nervous system or the blood, severe listeriosis can set in. Symptoms of severe listeriosis …
Listeriosis is diagnosed by laboratory testing of tissue samples and blood.
Most cases of listeriosis will clear after a few days. Complicated listeriosis in high-risk people requires medical attention.
Listeriosis is spread via contaminated food. A pregnant woman can transmit the bacteria to her unborn baby.
Although the chance of infection cannot be completely eliminated, listeriosis can be avoided by practising good food-handling practices. People at risk can avoid risky foods.
