An investigation is underway to identify the food source responsible for a multistate outbreak of listeria infections primarily involving people who either live in Florida or traveled there prior to becoming sick.
As of June 29, a total of 23 cases of listeriosis, a bacterial infection usually caused by eating food contaminated with listeria, were recorded in 10 states, causing 22 hospitalizations and one death.
Listeria infection is a foodborne bacterial illness that can be very serious for pregnant women, people older than 65 and people with weakened immune systems.
