Abstract: Out of 2145 food samples analysed 77 were found contaminated with Listeria monocytogenes in Santiago, Chile. Samples were: 603 ice-cream (3.5% contaminated), 256 soft cheese (0.8%), 155 hard cheese (0%), 229 baby milk bottles (0%), 634 processed meat products (3.6%) and 268 crustaceous shellfish (11.6%). Three different isolation media were used: for 318 samples, Modified McBride Agar (MMA), Lithium chloride Phenylethanol Moxalactam agar, and Polymyxin Acriflavine Lithium chloride Ceftazidime Aesculin Mannitol agar, for 1827 samples MMA was replaced by Listeria Selective Agar Oxford Formulation. Isolates were classified as follow: serovar 1/2a (25 isolates), serovar 4b (20), serovar 1/2b (19), serovar 3b (7), serovar 1/2c (2), untypable (4). A high variety of phagovars was detected although 52% of strains was untypable.
