Abstract
A survey of the prevalence of Shiga toxin-producing Escherichia coli (STEC) of O157 serotype in foodstuffs of animal origin (beef, veal, pork, chicken, fish) from 1999 to 2003 in Belgium was performed. STEC strains were only isolated from beef with a prevalence of 0.73%. This percentage is low in comparison with the prevalence in other countries. Among the 76 isolated STEC O157 strains, 75% belonged to the serotype O157:H7 and 25% to the serotype O157 non H7. Moreover, the most frequent pathotype was eae stx2 ehxA (74%).
Highlights
Two new legal texts from11th November 2003 published by the European parliament are dedicated to the survey and management of zoonoses and zoonotic agents in European Union: the directive 2003/99/CE [1] on the survey of zoonoses and zoonotic agents and the regulation 2160/2003/CE [2] on the control of Salmonella and other zoonotic agents present in food chain

Summary
Two new legal texts from11th November 2003 published by the European parliament are dedicated to the survey and management of zoonoses and zoonotic agents in European Union: the directive 2003/99/CE [1] on the survey of zoonoses and zoonotic agents and the regulation 2160/2003/CE [2] on the control of Salmonella and other zoonotic agents present in food chain. The O157 serotype was responsible for numerous outbreaks worldwide involving deadly cases [5] This justifies that EHEC O157 are subject to a very careful survey. An antibiotic treatment of the disease increases the risk of HUS appearance [6] Their major virulence factors are the Shiga-toxins Stx and Stx responsible for the kidney problems and the intimin encoded by the pathogenicity island LEE and involved in diarrhoea. The most foodstuffs from animal origin have been randomly sampled among the national production in order to evaluate the prevalence of EHEC O157 and the major incriminated pathotype
