Abstract

The present study was conducted to investigate the prevalence of Listeria spp < /em>. in some dairy products. A total of 240 samples of fresh cream, ice cream, butter milk cheese, Kareish cheese, Talaga cheese and yoghurt (40 of each) were collected randomly from different supermarkets, retail outlets and other markets outlets in Beni-Suef Governorate, Egypt. Out of 240 samples, 24(10%) were positive for Listeria species. The occurrence of Listeria spp < /em>. in fresh cream, ice cream, butter milk cheese and Kareish cheese was 6(15%), 8 (20%), 5 (12.5%) and 5(12.5%) respectively, while Listeria species couldn׳t be detected in any of Talaga cheese and yoghurt samples. The most prevalent species was L.grayii (45.83%), followed by L.monocytogenes (33.33%), and L.welshimeri (12.51%) and L. innocua 2(8.33%). All 8 L.monocytogenes isolates showed the presence of the hly A gene suggesting the possibility of danger of food borne listeriosis among dairy products consumers. In conclusion, the results of this study emphasize the need forapplying more strict hygienic control measures especially during processing, storage and marketing of dairy products.
