A total of 711 randomly selected samples were collected from supermarkets and pastry shops in Addis Ababa, Ethiopia. <span class=\"bold\">Listeria monocytogenes<\/span> and other <span class=\"bold\">Listeria<\/span> species were isolated and identified according to the techniques recommended by the International Organization for Standardization (ISO 11290-1). Serotyping of <span class=\"bold\">L. monocytogenes<\/span> strains was carried out at the French Food Safety Agency (AFSSA), Ploufragan, France. Of the 711 food samples examined, 189 (26.6%) were <span class=\"bold\">Listeria<\/span> positive of which 34 (4.8%) were <span class=\"bold\">L. monocytogenes<\/span>. Pork was the most contaminated with <span class=\"bold\">Listeria<\/span> species (62.5%) followed by minced beef (47.7%), ice cream (42.7%), soft cheese (16.8%), chicken carcasses (16.0%), and cakes (12.1%). All pasteurized milk and cottage cheese samples examined were <span class=\"bold\">Listeria<\/span> negative. <span class=\"bold\">Listeria monocytogenes<\/span> strains were isolated in ready-to-eat food items consisting of ice cream (11.7%), cakes (6.5%), and soft cheese (3.9%) and in meat products ranging from 3.7% to 5.1%. Among the 34 isolates of <span class=\"bold\">L. monocytogenes<\/span> serotyped, serotypes 4b\/4e (n = 32), 4c, and 4e (n = 2) were identified.
