UKHSA said the relatively stable number of STEC notifications in 2025 marked a departure from the steady annual increases observed since 2021, when larger outbreaks contributed substantially to case counts.
In 2025, a genetically unique hybrid STEC/STEC strain was the cause of a foodborne illness outbreak that affected exclusively adults, with 90 percent of patients developing hemolytic uremic syndrome (HUS) and three deaths occurring.
This article examines the frequent contamination of fresh produce (e.g., cucumber and sprouts due to recent outbreaks linked to these foods) with Salmonella and Shiga toxin-producing Escherichia coli.
The California Longitudinal Study, a five-year environmental study of California’s Central Coast produce-growing region, identified wildlife, livestock, and surface water as potential contributors to the persistence and movement of Shiga toxin-producing Escherichia coli (STEC).
The STEC O26:H11 outbreak sickened 40 people and resulted in 19 cases of hemolytic uremic syndrome (HUS) in children. Dried fruit was the probable vehicle of illness. Researchers underlined the importance of a weight-of-evidence approach in the outbreak investigation.
University of Georgia researchers conducted a review to compile and communicate best practices for reducing the spread of foodborne pathogens among beef cattle herds prior to processing, with a focus on Shiga toxin-producing Escherichia coli.
According to the newly published European Union One Health 2024 Zoonoses Report, the number of foodborne illnesses and outbreaks reported in the EU are on an upward trend. Notably, listeriosis cases with severe outcomes have risen.
In August, an outbreak of Shiga toxin-producing Escherichia coli O:157 (STEC) infections at Belgian long-term care facilities sickened more than 70 people, resulting in nine deaths. Raw ground beef is the probable vehicle of illness.
A CDC analysis of multistate foodborne illness outbreak investigation data for 2023 reveals the foods and pathogens that caused the greatest number of outbreaks and illnesses. A single salmonellosis outbreak linked to cantaloupe accounted for 407 illnesses.
England saw a 26 percent rise in Shiga toxin-producing Escherichia coli (STEC) infections from 2023 to 2024, and non-O157 STEC cases tripled since 2019. These trends may be driven by one foodborne illness outbreak involving contaminated salad leaves.
