Listeriosis is a rare and serious illness caused by eating food contaminated with bacteria called listeria. People who think they might have become ill should consult their doctor. A person from listeria usually has fever and muscle aches.

Listeriosis can be fatal, especially in certain high-risk groups. These groups include older adults, people with compromised immune systems and certain chronic medical conditions (such as cancer), and unborn babies and newborns. In pregnant women, listeriosis can cause miscarriage, stillbirth, and serious illness or death in newborn babies, though the mother herself rarely becomes seriously ill.

Eight people have died from the latest outbreak. Two of the deaths have been in Colorado.
