Symptoms of Listeriosis

There are a range of symptoms for listeriosis. Depending on the severity of the illness, symptoms may last from days to several weeks. Mild symptoms may include a fever, muscle aches, nausea, vomiting, and diarrhea. If the more severe form of listeriosis develops, symptoms may include headache, stiff neck, confusion, loss of balance, and convulsions. For the very young, the elderly, and the immune-compromised listeriosis can result in death.

People infected with L. monocytogenes may start to see symptoms in a few hours or as long as two to three days after eating contaminated food. More severe forms of listeriosis may take anywhere from three days to three months to develop.

Listeriosis can be particularly dangerous for pregnant women and their newborn babies, leading to serious complications with their pregnancy, including miscarriage and stillbirth. Babies born with a listeriosis infection may develop severe health complications that require immediate medical attention, lead to lifelong health problems, or result in death. Women who suspect they have symptoms of listeriosis (muscles aches, nausea, stiffness in neck, headaches, etc.) should seek medical care immediately and tell their health provider what they ate.

Due to the range in severity of illness, people should consult their health care provider if they suspect that they have developed symptoms that resemble a(n) L. monocytogenes infection.
