Listeriosis

Listeriosis is a serious infection usually associated with eating food contaminated with the bacterium Listeria monocytogene. An estimated 1,600 people get listeriosis each year, and about 260 die. The infection is most likely to sicken pregnant women and their newborns, adults aged 65 or older, and people with weakened immune systems.
