Symptoms Of Listeriosis (Listeria)

Fever

Like most infections, listeriosis typically presents with fever. Healthy individuals will rarely become ill from listeria, but those with compromised immune systems and newborns may exhibit a fever and other symptoms. The fever may start just a few days following the consumption of the contaminated food, but it's also possible up to a month will pass before individuals start exhibiting a fever or other infection symptoms. Fevers occur when the immune system raises the body's temperature as it fights the infection. A high fever is any fever greater than 103 degrees Fahrenheit. If patients experience a high fever, they may need emergency medical treatment to combat the listeria infection and prevent potential organ damage.
