The CDC is warning of a Listeria outbreak believed to be linked to deli meat that has sickened 10 people across multiple states.
The agency issued a warning about the outbreak on Friday.
Ten people spanning Florida, Massachusetts and New York have been hospitalized so far. One person in Florida has died.
According to the agency, deli meat is likely the source of the outbreak as nine of the 10 victims reported eating Italian-style meats like salami, mortadella, and prosciutto.
All victims reported purchasing prepackaged deli meats and meats sliced at deli counters at various locations. A supplier has yet to be identified.
The CDC noted that the median age of those infected was 81 with a majority being female.
Listeria is a serious infection caused by eating contaminated food. It primarily affects pregnant women, newborns, seniors, and those with weakened immune systems.
Symptoms usually begin one to four weeks after consuming contaminated food. They can include fever, muscle aches, headache, confusion, and loss of balance.
Anyone who is in the higher risk category should either avoid eating deli meat, lunch meat, or cold cuts unless it is heated thoroughly first.
The investigation into the current outbreak is ongoing.
