Presence of Escherichia coli O157:H7 in ground beef and ground baby beef meat

A total of 114 beef and baby beef samples were examined. The samples included ground baby beef, mixed ground baby beef and pork, and chopped and shaped meat. The samples were analyzed from 30 different grocery stores in Zagreb, Croatia. The object of this study was to evaluate the prevalence of Escherichia coli O157:H7 in the samples that can enhance the potential risk of outbreaks of hemorrhagic colitis and hemolytic uremic syndrome. The results in all tested samples of E. coli O157:H7 were negative. A single sample was positive in a latex agglutination test using antiserum to O157:H7. It was identified as Proteus vulgaris at the Pasteur Institute, Paris, France. This result correlates positively with cross-contamination with Yersinia enterocolitica 09, Brucella abortus, Salmonella type N, and Pseudomonas maltophila.
