Listeria monocytogenes is a foodborne pathogen of significant concern for the food industry due to its remarkable ability to persist through safety control efforts, posing a subsequent health threat to consumers. Understanding the microbial communities coexisting with L. monocytogenes in food processing environments provides insights into its persistence mechanisms.

is a food-borne pathogen, typically affecting the elderly, immunocompromised patients and pregnant women. The aim of this study was to determine the population structure of clonal complex 1 (CC1) in the UK and describe the genomic epidemiology of this clinically significant CC. We interrogated a working dataset of 4073 sequences of isolated between January 2015 and December 2020 from human clinical specimens, food and/or food-production environments.

Article Synopsis
  • The study aimed to compare antimicrobial resistance (AMR) genes in Salmonella enterica from imported foods in England between 2014 and 2018, focusing on Salmonella from edible leaves and raw chicken.
  • Whole genome sequencing showed that only 3% of Salmonella from edible leaves had AMR, while a significant 93% of chicken isolates exhibited resistance, with 71% being multidrug resistant (MDR).
  • The findings highlight the rarity of AMR in edible leaves compared to a high prevalence in raw chicken, emphasizing the need for monitoring AMR in imported foods to protect public health.

Abstract: Salad and other fresh produce were collected in England from retail and catering businesses during 2020 to 2021 and were tested for Salmonella, Shiga toxin-producing Escherichia coli (STEC), Listeria, Bacillus cereus, and E. coli. Of the 604 samples collected, 57% were from retail settings and 43% were from catering settings; 61% were either salad leaves or salad leaves mixed with other products.

Article Synopsis
  • Non-typhoidal Salmonella enterica is a leading cause of diarrheal illness, often linked to eating contaminated chicken, with Brazil being a significant supplier of chicken meat globally.
  • The study involved analyzing Salmonella genomes from Brazilian chickens and UK imports to identify prevalent serovars, focusing on S. enterica serovars Heidelberg and Minnesota, which were found to be common in both Brazil and UK meat products.
  • Genomic analysis revealed unique clades of these serovars with specific antimicrobial resistance genes, highlighting potential public health risks without a noted rise in incidence in the UK over time.
