Seven people in the UK have been affected by the virulent strain, including three Britons and four German nationals.
Early investigations suggest the strain is a mutant form of two different E.coli bacteria.
Hilde Kruse, a food safety expert at the WHO, told the Associated Press: “This is a unique strain that has never been isolated from patients before.”
She added that the new strain has “various characteristics that make it more virulent and toxin-producing”.
