ABSTRACT
Four hundred and forty samples of meat and meat products, 40 each of fresh meat, frozen ground beef, frozen beef sausage, frozen beef burger, hotdog, frankfurter, luncheon and basterma, were collected from different supermarkets and shops at Sharkia Governorate. Listeria species could be isolated from all examined samples at different percentages ranged from 7.5 to 42.5%, except in luncheon and basterma samples could not be isolated. Listeria monocytogenes could be isolated at variable percentage [2.5-10%] of the examined frozen beef, frozen kofta, frozen ground beef, frozen beef burger and frozen sausage. From the nine isolates of Listeria monocytogenes isolated from examined samples, seven strains were belonged to L. monocytogenes type 1 and two strains were belonged to L. monocytogenes type 4. The highest count of L. monocytogenes recorded as 3x104/g in frozen beef sausage sample. The public health hazard as well as suggestive measures to reduce human listeriosis has been discussed
