An E. coli outbreak linked to contaminated cucumbers that has killed 14 people and made more than 300 seriously ill in Germany has spread to other north European countries and is expected to worsen in the coming week, according to Reuters. "We hope that the number of cases will go down but we fear that it will worsen," said Oliver Grieve, spokesman for the University Medical Centre Schleswig-Holstein in north Germany, where many of those afflicted are being treated. The source of the virulent strain of the bacteria is unknown, German authorities said on Monday ahead of a crisis meeting of federal and state officials in Berlin. Most of the deaths have been in northern Germany. The E. coli pathogen has been identified on cucumbers imported from Spain but it is unclear if they were contaminated there, during transport or in Germany. There are 36 cases of suspected E. coli in Sweden, all linked to travel in northern Germany, authorities said. A small number of cases have been reported in Britain, Denmark, France and the Netherlands, all linked with travel to Germany. The German government has identified the pathogen as hemolytic-uremic syndrome (HUS), a serious complication of a type of E. coli known as Shiga toxin-producing E. coli (STEC), and said it had killed 14 people and made at least 329 ill. The European Centre for Disease Prevention and Control (ECDC) said in a risk assessment that the HUS/STEC outbreak is one the largest in the world of its kind. -- SPA
