As of December 17, 2019, a total of seven people infected with the outbreak strain of Listeria monocytogenes have been reported from five states.
Listeria specimens from ill people were collected from April 10, 2017, to November 12, 2019. Ill people range in age from less than 1 to 82 years, with a median age of 75. Seventy-one percent of ill people are male. Of six ill people with information available, four hospitalizations have been reported. One death has been reported from Texas. One illness was reported in a newborn who was infected with Listeria while the mother was pregnant, but the newborn survived.
Epidemiologic and laboratory evidence indicates that bulk hard-boiled eggs produced by Almark Foods of Gainesville, Georgia, are a likely source of this outbreak.
