The United Kingdom Health Security Agency (UKHSA) said yesterday that an additional 19 people have been sickened in an outbreak of Shiga toxin–producing Escherichia coli (STEC) that began in May, bringing the total to 275 cases.
Of the confirmed STEC cases, 182 are in England, 58 in Scotland, 31 in Wales, and 4 in Northern Ireland. Information from 249 case-patients shows that 49% have been hospitalized, and 2 people with underlying medical conditions have died.
Lettuce likely culprit
The outbreak was first identified on May 22 through UKHSA's routine surveillance. UKHSA says investigators believe a type of lettuce in pre-packaged sandwiches containing is the likely source of the outbreak.
"This remains a complex investigation and we continue to work with the relevant businesses and the local authorities to ensure necessary steps are being taken to protect consumers," Darren Whitby, Head of Incidents at the UK Food Standards Agency, said in a UKHSA press release. "Although we are confident in the likely source of the outbreak being linked to lettuce, work continues to confirm this and identify the root cause of the outbreak with the growers, suppliers and manufacturers so that actions can be taken to prevent a re-occurrence."
STEC can cause severe and sometimes bloody diarrhea, stomach cramps, vomiting, and fever.
