Listeria booriae is a Gram-positive, facultatively anaerobic, nonmotile, non-spore-forming rod-shaped species of bacteria. It is not pathogenic and nonhemolytic. It was discovered in a dairy processing plant in the Northeastern United States, and was first described in 2015. The species name honors "Kathryn Boor, a United States food scientist, for her contribution to the understanding of the biology of Listeria."[1]
