Listeria can cause serious and life-threatening illness in those infected. It is more likely to sicken pregnant women, their newborns, adults 65 years old or older and people with weakened immune systems. In this outbreak, one infant was hospitalized.
Listeria takes refuge in several food sources, including soft cheese, raw sprouts, melons, cold cuts and smoked seafood. In 2015, a major Listeria outbreak that affected hospital patients was linked to contaminated ice cream.
