From the 80’s, the increase of cases of human listeriosis and their possible relationship with contaminated foods, has come worrying to the worldwide sanitary authorities. Although in our country there are not reports of an association between listeriosis and contaminated foods, but, studies have been reported that have identified this bacterium in fresh and processed marine products, raw milk and their derived. The objective of the present research was to determine the incidence of Listeria monocytogenes in chickens and vegetables, obtained of diverse centers of supply and markets of Metropolitan Lima. In total, it was analyzed 100 samples, of which 50 were of fresh chicken meat and the other 50 ones of fresh vegetables (asparagus, cabbage, celery, spinach and lettuce). The microbiological analysis was carried out according to the methodology recommended in the Bacteriological Analytical Manual of the FDA and NF ISO 11290- 1. It was achieved to isolate Listeria monocytogenes from a chicken sample (2%) and from a sample of vegetable (2%), corresponding this last one to asparaguses. The strains were isolated using Oxford agar and Palcam agar like selective mediums and identified by means of biochemical tests. Key words: Listeria monocytogenes, fresh chicken, fresh vegetables, city of Lima, markets.
