ABSTRACT
Escherichia coli producing of Shiga-toxins and more particularly serogroupe 0157H7 are currently recognized like pathogenic the emergent significant ones in public health. These bacteria were detected at a great number of animal species without the latter presenting clinical signs of disease. However, the principal tank seems to be the cattle population. The prevalence of E. coli 0157H7 in the samples of deposit of the bovines varied from 4,8% to 36,8%. The persistence of the strains of STEC in the livestock is due, on the one hand, with the intestinal bearing by the animals, and on the other hand, with the contamination of the grounds and water starting from the animal manure being able to be at the origin of a contamination of food. Moreover, the persistence of germ in the animals depends on several factors to knowing seasonal variation, mode of watering and food. The risk of contamination of the food products of animal origin is a function of the importance of the animal bearing, but also of the respect of the procedures of hygiene applied in particular in slaughter-house and in the workshops of transformation
