The UK Health Security Agency (UKHSA) has issued new advice following a rise in cases linked to the recent outbreak of Shiga toxin-producing E. coli (STEC) O145. As of 3 July, an additional 13 cases have been confirmed since the last update on 27 June, bringing the total number of cases across the UK to 288. The outbreak has predominantly affected England, with 191 confirmed cases, followed by 62 in Scotland, 31 in Wales, and 4 in Northern Ireland. The cases in Northern Ireland are believed to have originated in England.
Although the number of newly reported cases is decreasing, UKHSA expects to see a small number of additional cases as more samples are referred from NHS laboratories and undergo whole genome sequencing. Of the 263 cases analyzed so far, nearly half (49%) required hospitalization, highlighting the severity of the outbreak.
Amy Douglas, the Incident Director at UKHSA, expressed cautious optimism about the declining case numbers but warned that more cases might emerge as further testing is conducted. She emphasized the importance of taking preventive measures to reduce the risk of infection, including washing hands thoroughly with soap and warm water, using disinfectants to clean surfaces, and avoiding food preparation and visits to hospitals or care homes while unwell. Douglas also advised the public to follow NHS guidance on when to seek help and to stay home from work, school, or nursery for 48 hours after symptoms subside to prevent further spread.
The Food Standards Agency (FSA) is continuing its investigation into the outbreak, focusing on identifying the source and ensuring consumer safety. Darren Whitby, Head of Incidents at the FSA, confirmed that the investigation has linked the outbreak to a type of lettuce used in various sandwich products. Several sandwich manufacturers have already taken precautionary measures by withdrawing and recalling products. Whitby acknowledged the complexity of the investigation and the ongoing efforts to trace the outbreak back to its root cause, working closely with growers, suppliers, and manufacturers to prevent a recurrence.
The UKHSA also reported that two individuals in England who were infected with the outbreak strain of STEC died within 28 days of their infection. While one of these deaths is likely linked to the STEC infection, both individuals had underlying health conditions, making them more vulnerable to severe outcomes.
As the number of cases linked to this outbreak continues to decline, the UKHSA announced that the update on 5 July would be the final weekly report on case numbers unless a significant change occurs. Despite the positive trend, authorities remain vigilant, urging the public to stay informed and take necessary precautions to protect themselves and others from this potentially serious infection.
