The E. coli O157 in the United Kingdom that has been linked to eating mixed salad leaves appears to be slowing as no additional cases have been reported in the past week.


The outbreak tally remains at 161 (England 154, Wales 6 and Scotland 1) and two fatalities.

Public Health England (PHE) , based on whole genome sequencing and other techniques, say testing has indicated that the strain involved is likely to be an imported strain, possibly from the Mediterranean area.

Dr Isabel Oliver, Director of PHE’s field epidemiology service, said, “We are very pleased to see there have been no further cases reported over the past week, which suggests we are over the worst for this outbreak.

“Our investigations to identify the source of the contaminated salad leaves are continuing.”
