Currently, Swedish authorities are investigating a national outbreak of E. coli. At least 50 cases have been reported.

Folkhälsomyndigheten (Public Health Agency) and Livsmedelsverket (National Food Agency) said it appears to be one of the biggest outbreaks of infections from the potentially deadly pathogen that the country has ever had. Sweden usually records about 30 to 50 domestic cases during July.

The bacteria behind the outbreak is Enterohemorrhagic E. coli (EHEC). The outbreak strain, EHEC O157:H7, is known for its high virulence. Infections have been reported from several counties, but mainly Uppsala and Västra Götaland.
