Main points

A total of 402 confirmed cases of Shiga toxin-producing Escherichia coli (STEC) O157 were reported in England and Wales in 2020.

The lowest incidence of STEC O157 was in the London region (0.29 per 100,000 population) and the highest in the South West region (1.04 per 100,000 population).

Children aged 5 to 9 years had the highest incidence of infection (1.50 per 100,000 population, 95% confidence interval (CI) 1.12 to 1.96).

One-third of confirmed STEC O157 cases in England were hospitalised and 3% were reported to have developed Haemolytic Uraemic Syndrome (HUS).

A further 286 specimens in England and 41 in Wales were positive for Shiga toxins (Stx) genes on polymerase chain reaction (PCR) at the Gastrointestinal Bacteria Reference Unit (GBRU) but an organism was not cultured.

The most commonly isolated non-O157 STEC serogroup was STEC O26 (England: n=103 out of 553, 19%; and Wales: n=26 out of 268, 15%).

Three outbreaks of STEC involving 63 cases in England were investigated in 2020.

UK – Shiga toxin-producing Escherichia coli (STEC) data: 2021

Updated 18 April 2024

The main points of the 2021 annual report are:

Overall, 1,181 confirmed cases of STEC were reported in England during 2021, a decrease of 2% compared to 2020.

A total of 365 confirmed cases of Shiga toxin-producing Escherichia coli (STEC) O157 were reported in England in 2021, no change compared to 2020. A total of 1,234 confirmed cases of Shiga toxin-producing Escherichia coli (STEC) non-O157 were reported in England in 2021, an increase of 46% compared to 2020.

The lowest annual incidence of STEC O157 was in the East Midlands region (0.41 per 100,000 population) and the highest in the North East region (1.02 per 100,000 population). The lowest incidence of STEC non-O157 was in the Yorkshire and Humber region (0.62 per 100,000 population) and the highest in the London region (4.21 per 100,000 population).

Children aged 1 to 4 years had the highest annual incidence of infection due to STEC O157 (2.3 per 100,000 population, 95% confidence interval (CI) 1.78 to 3.02). Children aged under 1 years had the highest incidence of infection due to STEC non O157 (7.08 per 100,000 population, 95% confidence interval (CI) 7.01 to 7.21).

Around a third (36%, 127 out of 365) of confirmed STEC O157 cases in England were hospitalised and 2% (6 out of 365) were reported to have developed haemolytic uraemic syndrome (HUS). Where information is available, two-thirds (65%, n=274 out of 431) of confirmed STEC non-O157 cases in England were hospitalised; and 1% (14 out of 1,234) of all STEC non-O157 were reported to have developed HUS).

A further 443 specimens in England were positive for stx genes on PCR at the Gastrointestinal Bacteria Reference Unit (GBRU), indicating STEC, but an organism was not cultured therefore a STEC serogroup could not be ascertained.

The most commonly isolated non-O157 STEC serogroup was STEC O26 (n=145 out of 786, 18%).

Four outbreaks of STEC in England involving 52 cases, ranging from 10 to 19 cases, were investigated in 2021: 2 involved STEC O157 and suspected vehicles were identified and 2 involved STEC O26 outbreaks and no vehicles were identified.

Since 2018, the number of STEC O157 notifications has declined and the number of STEC non-O157 has increased two-fold (218%). Overall, there is an increase in STEC notifications, and the burden placed on public health and clinical services is also increasing, especially given the two-fold increase in hospitalisation reported in 2021 for non-O157 cases.

Research – Genomic surveillance of STEC/EHEC infections in Germany 2020 to 2022 permits insight into virulence gene profiles and novel O-antigen gene clusters

Posted on March 18, 2024 by | Leave a comment

Abstract

Shiga toxin-producing E. coli (STEC), including the subgroup of enterohemorrhagic E. coli (EHEC), are important bacterial pathogens which cause diarrhea and the severe clinical manifestation hemolytic uremic syndrome (HUS). Genomic surveillance of STEC/EHEC is a state-of-the-art tool to identify infection clusters and to extract markers of circulating clinical strains, such as their virulence and resistance profile for risk assessment and implementation of infection prevention measures. The aim of the study was characterization of the clinical STEC population in Germany for establishment of a reference data set. To that end, from 2020 to 2022 1257 STEC isolates, including 39 of known HUS association, were analyzed and lead to a classification of 30.4 % into 129 infection clusters. Major serogroups in all clinical STEC analyzed were O26, O146, O91, O157, O103, and O145; and in HUS-associated strains were O26, O145, O157, O111, and O80. stx1 was less frequently and stx2 or a combination of stx, eaeA and ehxA were more frequently found in HUS-associated strains. Predominant stx gene subtypes in all STEC strains were stx1a (24 %) and stx2a (21 %) and in HUS-associated strains were mainly stx2a (69 %) and the combination of stx1a and stx2a (12.8 %). Furthermore, two novel O-antigen gene clusters (RKI6 and RKI7) and strains of serovars O45:H2 and O80:H2 showing multidrug resistance were detected. In conclusion, the implemented surveillance tools now allow to comprehensively define the population of clinical STEC strains including those associated with the severe disease manifestation HUS reaching a new surveillance level in Germany.

11 sick in French cheese STEC O26 E. coli outbreak

Posted on February 15, 2024 by | Leave a comment

Food Safety News

The number of children sick in a severe E. coli outbreak in France linked to raw milk cheese has risen to 11.

The 11 hemolytic uremic syndrome (HUS) cases were reported in late 2023. HUS is a severe complication associated with E. coli infections that causes kidney failure. Santé publique France surveillance on HUS only covers children younger than 15 years old in the country, so there could be other sick people in the outbreak.

Five young children attending the Minimes crèche in Toulouse had to be hospitalized in November. Stool cultures revealed Shiga toxin-producing E. coli (STEC) infection. Cheese has tested positive for E. coli O26.

The other six children with HUS infected with the outbreak strain are unrelated to the crèche and live in different regions.

Speaking to different French media outlets, the parents of two girls, Élise, aged 7, and Clara, 18 months old, revealed how their children had been affected and their ongoing health issues

France – Raw milk cheese sickens six children in France – STEC E.coli O26

Posted on December 18, 2023 by | Leave a comment

Food Safety News

A cheese made from raw milk has been linked to half a dozen serious E. coli infections in France.

Six cases of hemolytic uremic syndrome (HUS) have been reported. HUS is a severe complication associated with E. coli infections that causes kidney failure.

Following severe diarrhea, young children attending the Minimes crèche in Toulouse had to be hospitalized in November. Stool cultures revealed Shiga toxin-producing E. coli (STEC) infection. Cheese has tested positive for E. coli O26.

The crèche was closed for a few days, but has since reopened. Samples from surfaces were taken and analyzes of the meals were carried out as well as a thorough cleaning of the premises.

Denmark Solves E. coli Outbreak; More Sick in Norwegian outbreak

Posted on November 8, 2023 by | Leave a comment

Food Safety News

The SSI, Danish Veterinary and Food Administration (Fødevarestyrelsen), and DTU Food Institute investigated the outbreak that was linked to a type of beef steak, thanks to patient interviews.

Meanwhile, in Norway, four other cases have been added to a different E. coli outbreak.

The Norwegian Institute of Public Health (FHI) reported that E. coli O26:H11 had been detected in 24 people. It is one of the country’s most severe E. coli outbreaks.

Fifteen of those infected are under the age of 13, and nine children have developed hemolytic uremic syndrome (HUS).
