What is a Listeria outbreak?

A listeria outbreak is a situation where two or more people get sick from eating food contaminated with the bacteria Listeria monocytogenes. This can happen when food is processed, prepared, or stored in unsanitary conditions. Listeria outbreaks are typically identified when multiple individuals experience similar illnesses after consuming the same potentially contaminated food.

Why is Listeria such a concern?

Listeria monocytogenes is a pathogenic bacterium that thrives in refrigerated environments, unlike many other foodborne pathogens.

While healthy individuals might experience mild symptoms, including fever, muscle aches, nausea, or diarrhea, the infection can escalate to more severe conditions, such as meningitis, particularly in those over 65, pregnant individuals, newborns, or the immunocompromised.

According to FDA data, listeriosis is the third-leading cause of death from foodborne illness in the US, responsible for approximately 260 deaths annually.

Listeriosis: Symptoms and prevention

Listeria can be particularly dangerous for pregnant women, older adults, and individuals with weakened immune systems.Listeriosis symptoms can range from mild, like fever and diarrhea, to severe, including meningitis or sepsis, especially in vulnerable populations. Listeria can be transmitted through contaminated food, and outbreaks are often linked to ready-to-eat foods like deli meats, soft cheeses, and smoked seafood.Proper food handling, including cooking to safe temperatures and avoiding high-risk foods, is crucial to prevent listeriosis.
