USA – Lower Valley Processing recalls beef due to E. coli O157:H7

Food Poison Journal

Lower Valley Processing, Official Establishment No. 007 located in Kalispell, Montana, has voluntarily recalled all non-intact, raw products (e.g., ground meat products) produced from animals slaughtered on June 5, 2024, because they may be adulterated with Escherichia coli 0157:H7, the Montana Department of Livestock announced today. Potentially affected products were labeled with “Lower Valley Processing, Co.”, establishment number “EST. 007” inside the Montana mark of inspection on the product labels, and lot numbers 1398, 1399, and 1400. The source of the E. coli contamination has not been identified.

Research – Shiga Toxin-Producing Escherichia coli Strains from Romania: A Whole Genome-Based Description

MDPI

Abstract

The zoonotic Shiga toxin-producing Escherichia coli (STEC) group is unanimously regarded as exceptionally hazardous for humans. This study aimed to provide a genomic perspective on the STEC recovered sporadically from humans and have a foundation of internationally comparable data. Fifty clinical STEC isolates, representing the culture-confirmed infections reported by the STEC Reference Laboratory between 2016 and 2023, were subjected to whole-genome sequencing (WGS) analysis and sequences were interpreted using both commercial and public free bioinformatics tools. The WGS analysis revealed a genetically diverse population of STEC dominated by non-O157 serogroups commonly reported in human STEC infections in the European Union. The O26:H11 strains of ST21 lineage played a major role in the clinical disease resulting in hospitalisation and cases of paediatric HUS in Romania surpassing the O157:H7 strains. The latter were all clade 7 and mostly ST1804. Notably, among the Romanian isolates was a stx2a-harbouring cryptic clade I strain associated with a HUS case, stx2f– and stx2e-positive strains, and hybrid strains displaying a mixture of intestinal and extra intestinal virulence genes were found. As a clearer picture emerges of the STEC strains responsible for infections in Romania, further surveillance efforts are needed to uncover their prevalence, sources, and reservoirs.

UK – Update on reporting of non-O157 STEC infections and an outbreak of Shiga toxin-producing E. coli (STEC) O145 in the UK, February 2024

Gov UK

In December 2023 the UK Health Security Agency (UKHSA) reported (1) unseasonably high levels of Shiga toxin-producing Escherichia coli other than serogroup O157 (non-O157 STEC) case notifications during October to December of that year. Since then, reporting has returned to levels comparable with previous years. Investigations into the drivers of that unseasonal increase in reports of non-O157 STEC continue, as well as into individual outbreaks of STEC that were reported in the December 2023 report.

The investigations into the concurrent foodborne STEC O145: H28 outbreak associated with unpasteurised cheese – being undertaken by UKHSA, the Local Authority (LA) Environmental Health Team, Public Health Scotland (PHS), Food Standards Agency (FSA), Food Standards Scotland (FSS) and the Animal Plant Health Agency (APHA) – are nearly completed.

In total 36 confirmed cases and 1 probable case have been reported across England (n=29) and Scotland (n=8) since late July 2023, with most cases falling ill in November 2023. The last reported primary case had a symptom onset date of 23 December 2023 (see figure below).

Based on epidemiological, food chain and microbiological investigations, the vehicle was identified as an unpasteurised cheese produced in North West England. The food business concerned carried out a product withdrawal and recall on 24 December 2023 (2) and updated on 27 December 2023 (3) which ensured all recalled products were removed from sale in a timely manner.

Subsequent work between the food business, the LA Environmental Health team and the FSA allowed refinement of the product withdrawal and recall notice to include only the batches likely associated with illness, which resulted in a further update of the product withdrawal and recall by the food business on 9 February 2024 (4).

The FSA and FSS both published updated Product Recall Information Notices (PRIN’s) on 24 (2) and 27 December (3), and again on 9 February (4), with supporting news stories to amplify messaging about each of the product recalls.

USA – Hamburger E. coli O157 Outbreak sickens 13 with 1 death in Montana

Food Poison Journal

The Flathead City-County Health Department (FCCHD), the Montana Department of Public Health and Human Services (DPHHS), and other local health departments, are working together to investigate an E.coli O157:H7 outbreak originating in Flathead County.

To date, the investigation has identified at least 13 individuals associated with the outbreak. Many of the cases experienced moderate to severe symptoms, and one death has occurred. Preliminary investigative findings indicate that ground beef containing the E.coli bacteria may be the exposure of concern. State partners continue to test clinical and food samples for laboratory confirmation.mp

Research – Survival of Salmonella spp., Escherichia coli O157:H7, and Listeria monocytogenes in Ready-to-Eat “Guacamole”: Role of Added Antimicrobials

MDPI

Abstract

Ensuring the microbiological safety of food products is majorly important to regulatory agencies, producers, and consumers. This study aimed to examine the effects of three different antimicrobial agents, including chitosan (CH), mastic oil (M), and citric acid (CA), individually or as a combination, against Salmonella spp., Escherichia coli O157:H7, and Listeria monocytogenes (artificially inoculated) in Guacamole, a ready-to-eat (RTE) avocado-based salad. The Guacamole samples included untreated samples, designated as CNL, and samples treated as follows: CA 0.15% and CA 0.30% with citric acid added at 0.15% and 0.30% v/w; CH 0.5% and CH 1% with chitosan at 0.5 and 1% v/w; M 0.2% and M 0.4% with mastic essential oil (EO) at 0.2% and 0.4% v/w; CACH with CA 0.30% and CH 1% v/w; CAM with CA 0.30% and M 0.4% v/w; CHM with CH 1% and M 0.4% v/w; and CACHM with CA 0.30%, CH 1%, and M 0.4% v/w. Microbiological evaluation, monitoring of the pH values, and proximate analyses (moisture, fat, protein, ash, and water activity) were performed at different time intervals (days 0, 1, 3, 5, and 7) at two storage temperatures (4 and 10 °C). Antimicrobial treatments, particularly CH 1% and CACHM, effectively (p < 0.05) reduced Salmonella spp. and E. coli O157:H7 populations at 4 °C, while CACHM showed the most efficacy against L. monocytogenes. However, at 10 °C, antimicrobials had limited impact, and the bacterial counts exhibited an increasing trend during storage. The pH values in the avocado-based salad samples showed, in general, higher decreases at 10 compared to 4 °C, with the CHM combination showing the highest antimicrobial effect.
