Another woman died in Germany on Wednesday after being treated for infection with the virulent enterohaemorrhagic E. coli (EHEC) bacteria on Wednesday, as government minister warned the situation remained "threatening."

Consumer Affairs Minister Ilse Aigner and Health Minister Daniel Bahr called for everyone to take particular care with food hygiene at a press conference in Berlin.

Except the public health authority, the Robert Koch Institute (RKI) advised this evening not to eat any tomatoes, cucumbers or lettuce from northern Germany.

Sounds like an on-farm problem, not a consumer problem; needs to be prevented, isn’t going to be washed off.

The latest woman to die was a 41-year-old from Cuxhaven – although she was being treated for the symptoms of EHEC infection since May 21, her cause of death will now be investigated.

The number of people confirmed to have died in Germany from EHEC infection has reached three. But health officials said an elderly woman who died on Sunday in Stormarn, Schleswig Holstein, was not killed by the bacteria.
