A 78-year-old woman in Bordeaux, France died from E. coli on Saturday morning, but it was not the same strain that has killed 50 related to sprouts in Germany.

She had been hospitalized since June 24 with hemolytic uremic syndrome — the kidney condition that the most seriously ill victims of the outbreak are suffering from.

Seven other patients remain at the same French hospital, six of whom have been confirmed to have the same strain of E.coli O104 as in the outbreak that originated in Germany. European health experts said Thursday that contaminated Egyptian fenugreek seeds were likely the source of that deadly outbreak.

In Sweden, the centre for communicable diseases (Smittskyddet) in Skåne, is now giving up attempts to find the source behind the first Swedish infection of the virulent enterohaemorrhagic E.coli (EHEC) bacteria.

Last Tuesday, a Swedish man with no apparent connections to Germany was infected with the bacteria, marking the first domestic case in Sweden.

"All previous Swedish cases had a connection to Germany, but not this," said Sofie Ivarsson, epidemiologist at the Swedish Institute for Communicable Disease Control (Smittskyddsinstitutet) to news agency TT at the time.

"This means that the source of the infection is in Sweden, which is a lot worse, because it might mean that there is some form of infected food product in circulation that we haven’t yet identified."
