Mat\u00eds can identify whether E.coli<\/em> STEC is in food products<\/strong><\/h3>\n\n\n\n

Over the past two weeks, Mat\u00eds' experts have been working hard to trace the source of the group infection E. coli<\/em> STEC that appeared in a kindergarten in Reykjav\u00edk in mid-October. The study was carried out in close collaboration with the National Food Agency, the Epidemiologist, the Department of Pathology and Virology of Landsp\u00edt\u00e1l and the Reykjav\u00edk Health Authority.<\/h4>\n\n\n\n

A number of suspect foods were screened for
E. coli<\/em> STEC but this bacterium can hide in many places. It soon became clear that mincemeat, which was used in cooking at the kindergarten, was by far the most likely source of the infection. A large number of bacterial strains were cultured from the mince, and finally three strains containing characteristic virulence genes and of the same serotype as the strain isolated from the patient were isolated. The genomes of these four strains were finally sequenced at Mat\u00eds. That analysis revealed that the strains from the hack and the patient were genetically identical. Mat\u00eds was a pioneer in the implementation of this methodology in Iceland to trace the origin of foodborne infections.<\/p>\n\n\n\n

Finally, Mat\u00eds would like to draw attention to the fact that the company offers analyzes of E. coli<\/em> STEC in food. Mat\u00eds is a reference laboratory (NRL) for these analyzes in Iceland. This means that Mat\u00eds constantly updates his methods according to the latest knowledge and methods in Europe. E. coli <\/em>STEC is a bacteria that can cause serious illness.<\/p>\n\n\n\n
