Researchers have detailed the first E. coli O103 outbreak in England traced to raw milk cheese.

In June 2022, routine microbiological surveillance at the UK Health Security Agency (UKHSA) identified 12 Shiga toxin-producing E. coli (STEC) O103:H2 cases.

People fell ill between May and June 2022. Seven cases were female

Scientists have detailed the process of linking a major E. coli outbreak in the United Kingdom to lettuce.

In May 2024, public health agencies and laboratories identified an increase in stool specimens submissions and patients testing positive for Shiga toxin-producing E. coli (STEC). Whole genome sequencing (WGS) identified serotype O145:H28

A bacterium closely related to E. coli caused an outbreak in China in 2023 but the probable contaminated food source was not identified. Researchers believe it to represent the first reported outbreak of gastroenteritis attributed to E. albertii outside of Japan.

Escherichia albertii infections typically cause watery diarrhea, abdominal pain

An investigation into related Salmonella infections in the United Kingdom has revealed multiple vehicles and pathways of infection.

Following an outbreak of Salmonella Typhimurium in Wales in 2021, which was associated with sheep meat and lamb liver being consumed raw, other genetically related cases were found across the UK. The

Researchers have suggested ways to improve analysis to help with source attribution and Campylobacter outbreak investigations. 

The standard method of Campylobacter detection is through culture, though feasibility constraints usually result in selecting or characterizing as few as one isolate per sample.

Only taking a few isolates can lead to the

International travel is a major risk factor for developing a range of infections, according to a study in a region of England.

Scientists found illness after travel abroad contributes substantially to the burden of infection in North East England. There has also been no reduction in the proportion of travel-associated

Researchers say current guidance on excluding children with E. coli from childcare does not need to be changed despite the recording of more non-O157 cases.

According to the researchers, excluding children with Shiga toxin-producing E. coli (STEC) until the pathogen is microbiologically clear disrupts families, education, and earnings.

Scientists examined

Researchers have analyzed travel-associated infections in people returning to the United States from abroad.

From 2017 to 2020, the Centers for Disease Control and Prevention investigated 41 multistate outbreaks of non-typhoidal Salmonella and Shiga toxin-producing E. coli (STEC) linked to international travel.

In the same time frame, CDC handled 470
