Listeria cases defined as isolation of L. monocytogenes from a normally sterile site or, in the setting of miscarriage or stillbirth, isolation of L. monocytogenes from placental or fetal tissue. In cases of pregnancy-associated listeriosis, case may be mother, infant, or both, depending on source(s) of isolation.
