New data shows deceleration of UK E. coli outbreak

The recent outbreak of E. coli 0157 appears to be losing momentum, according to the latest government data.

Public Health England has confirmed that 160 cases of this strain of E. coli have been identified since the outbreak – associated with eating mixed salad leaves – commenced, with 153 of these cases seen in England, six in Wales and one in Scotland.

A significant reduction in the number of cases has been observed, with only nine reported over the past week and those affected reporting the last onset of symptoms on July 5th. This suggests the worst of the outbreak may have passed.

Whole genome sequencing analysis of samples from those affected has indicated that the strain involved is likely to be imported, possibly from the Mediterranean area. Some wholesalers have therefore been advised to stop adding certain non-UK salad leaves to their mixed salad products.

In the meantime, people are advised to pay close attention to hygiene measures, such as properly washing vegetables and cleaning their hands after handling animals or going to the bathroom.

Dr Isabel Oliver, director of Public Health England's field epidemiology service, said: "Public Health England is working alongside the Food Standards Agency and will provide any further necessary public health advice as investigations continue."
