This study was conducted to investigate the existence and spread of Listeria monocytogenes in different types of red meat. Three hundred and eighteen samples were collected included 100 Cattle meat, 112 sheep meat, and 106 Goats meat. The prevalence of Listeria monocytogenes in total samples was N 73 (22.9 %). The highest isolation rate of the bacteria agents in Cattle meat was N 26 (26.0%), followed by Goats meat N 27 (25.5%), and then Sheep meat with N 20 (17.9%). There are no significant differences at (p > 0.05) between prevalence of Listeria monocytogenes in different types of red meat. When we study the relationship between prevalence of Listeria monocytogenes and months, we noticed that the highest isolation rate was in August (45.9%) and followed by May (38.2%). The results indicated that there were significant differences at (p < 0.05) in Goats meat, but there were no significant differences at (p > 0.05) in Cattle meat and Sheep meat.
