First detection of Shiga toxin-producing Escherichia coli in shellfish and coastal environments of Morocco.

Shiga toxin Escherichia coli (STEC), also called verotoxin-producing E. coli, is a major cause of food-borne illness, capable of causing hemorrhagic colitis and hemolytic-uremic syndrome (HUS). This study was carried out to evaluate the presence of (STEC) and E.

Sequence analysis of the gene encoding H antigen in Escherichia coli isolated from food in Morocco.

In order to develop other molecular method useful for typing of motile and non motile Escherichia coli strains, a total of 207 strains of E. coli (133 reference strains, 74 food strains) were characterized by analysis of sequences of their amplified flagellin-encoding (fliC) gene products. The collection of reference strains was used for database building of fliC gene sequences.

Microbial quality control of raw ground beef and fresh sausage in Casablanca (Morocco).

In this study, samples of raw ground beef (n = 150) and fresh sausage (n = 100) were collected randomly from butcheries, supermarkets, and fast-food shops, in Casablanca, Morocco. Two types of meat product samples were considered, one with spices (n = 115) and other without spices (n = 135). All the samples were analyzed for the presence of the following bacteria: Escherichia coli, Staphylococcus, Clostridium perfringens, Salmonella, and Listeria monocytogenes.
