Listeria monocytogenes is a food borne pathogen frequently associated with the consumption of contaminated food. Severe and life threatening human diseases caused by Listeria monocytogenes has been reported throughout the world. The present study evaluated the prevalence and antibiograms of Listeria monocytogenes isolated from yoghurt and raw milk sample in Zaria, Kaduna State. A total of three hundred and sixteen samples of yoghurt and raw milk samples were purchased within Zaria, Kaduna State. The samples were bacteriologically analyzed in the laboratory for the presence of Listeria monocytogenes using conventional biochemical tests. Antibiotic susceptibility profiles showed that all the isolates were resistant to three or more antibiotics except for the aminoglycoside gentamicin to which all the isolates were susceptible (100%). Nine different resistance patterns were observed with resistance to ampicillin being the most predominant (100%). The minimum MAR index was 0.27 indicating that isolates were from a source of high antibiotics abuse. Key words: Listeria monocytogenes, raw milk, multiple antibiotic resistance index (MAR)
