According to health officials on Thursday, a new listeria outbreak of unknown origin has resulted in one death and nearly two dozen hospitalizations.
Although the Centers for Disease Control and Prevention has not identified a food that may be spreading the deadly bacteria, officials have warned the public to be aware of symptoms and the possibility of infection.
Fever, muscle aches, nausea, and diarrhea are among the symptoms.
Antibiotics can be used to treat Listeria, but it is especially dangerous to pregnant women, newborns, the elderly, and those with compromised immune systems.
According to the CDC, nearly all the 23 people known to have been infected in the outbreak either lived in or traveled to Florida about a month before becoming ill.
Listeria is one of the deadliest types of food poisoning, and 22 of those infected were hospitalized. According to the CDC, one person died in Illinois, and one pregnant woman lost her fetus.
Listeria symptoms typically appear one to four weeks after consuming contaminated food, but they can appear as soon as the next day.
The first cases were reported in January of this year, but they continued until June, when two of the people became ill, according to CDC officials.
