The Benjamin CaldwellCenters for Disease Control and Prevention issued a food safety alert Monday about a listeria outbreak linked to recalled peaches, nectarines and plums.

The recalled fruit has so far led to 11 reported illnesses, including 10 hospitalizations and one death across seven states, according to the CDC. Investigators are working to determine if any additional fruit or products made with this fruit may be contaminated.

The affected fruits were sold in stores nationwide between May 1 and Nov. 15, 2022, and the same date range in 2023.

The states where people have reported illnesses so far are California, Colorado, Kansas, Illinois, Michigan, Ohio and Florida, according to the CDC.

The fruit was sold in two-pound bags branded "HMC Farms" or "Signature Farms," according to the CDC, and was also sold as individual fruit with a sticker that has "USA-E-U" and a number on it.

What is listeria? What are the symptoms?

Listeria is an organism that can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems, according to the FDA.

Symptoms include high fever, severe headaches, stiffness, nausea, abdominal pain and diarrhea. Listeria can also cause miscarriages and stillbirths among pregnant women.

According to the CDC, symptoms usually start within two weeks after eating food contaminated with listeria, but may start as early as the same day or as late as ten weeks after.
