What symptom is commonly associated with Listeria monocytogenes infection?

The correct answer indicates that nausea, vomiting, and abdominal pain are all symptoms that can be associated with a Listeria monocytogenes infection. Listeria, a bacterium found in contaminated food, can lead to a range of symptoms reflecting mild gastrointestinal distress. In particular, nausea and vomiting are common early signs of infection, as the body attempts to rid itself of the pathogen. Additionally, abdominal pain can occur due to the inflammation and irritation in the gastrointestinal tract as a result of the infection.

Listeriosis, the illness caused by Listeria monocytogenes, often mimics other foodborne illnesses, which is why these symptoms are frequently observed. It is essential to recognize these signs, particularly in vulnerable populations such as pregnant women, newborns, elderly individuals, and those with weakened immune systems, as they can lead to more severe complications. Understanding the broad range of symptoms helps in identifying potential Listeria infections and emphasizes the importance of proper food handling and preparedness measures to prevent ingestion of harmful bacteria.
