“…Alternatively, S. enterica can be subdivided into approximately 2,500 different serotypes according to somatic (O) and flagellar (H) antigens (Tindall et al , 2005; Grimont and Weill, 2007). S. enterica subspecies I causes the majority of cases of foodborne diarrhoea (Sanchez‐Vargas et al , 2011; Rezende et al , 2016). S. enterica subspecies I exhibits approximately 1531 serotypes (Desai et al , 2013; Lamas et al , 2018).…”

Summary The development of DNA sequencing technology has provided an effective method for studying foodborne and phytopathogenic microorganisms on fruits and vegetables (F & V). DNA sequencing has successfully proceeded through three generations, including the tens of operating platforms. These advances have significantly promoted microbial whole‐genome sequencing (WGS) and DNA polymorphism research. Based on genomic and regional polymorphisms, genetic markers have been widely obtained. These molecular markers are used as targets for PCR or chip analyses to detect microbes at the genetic level. Furthermore, metagenomic analyses conducted by sequencing the hypervariable regions of ribosomal DNA (rDNA) have revealed comprehensive microbial communities in various studies on F & V. This review highlights the basic principles of three generations of DNA sequencing, and summarizes the WGS studies of and available DNA markers for major bacterial foodborne pathogens and phytopathogenic fungi found on F & V. In addition, rDNA sequencing‐based bacterial and fungal metagenomics are summarized under three topics. These findings deepen the understanding of DNA sequencing and its application in studies of foodborne and phytopathogenic microbes and shed light on strategies for the monitoring of F & V microbes and quality control.

“…It is critical to highlight that the processing and washing water in tanks can accumulate microorganisms from fruits and vegetables, potentially leading to further contamination (EFSA, 2023). If washing water is contaminated with pathogens, these pathogens potentially risk internalizing within the tissues of the produce (Esteban-Cuesta et al, 2018;Rezende et al, 2016;Ssemanda et al, 2018). While many studies have explored the potential for root uptake internalization of human bacterial pathogens like Salmonella in fruits and vegetables, the research on internalization through wounded tissue of fresh-cut leafy greens during washing in processing is not as comprehensive (EFSA, 2014d;Thomas et al, 2024).…”

This research presents a comprehensive review of Salmonella presence in retail fresh fruits and vegetables from 2010 to 2023, utilizing data from recognized sources such as PubMed, Scopus, and Web of Science. The study incorporates a meta‐analysis of prevalence, serovar distribution, antimicrobial susceptibility, and antimicrobial resistance genes (ARGs). Additionally, it scrutinizes the heterogeneous sources across various food categories and geographical regions The findings show a pooled prevalence of 2.90% (95% CI: 0.0180−0.0430), with an increase from 4.63% in 2010 to 5.32% in 2022. Dominant serovars include S. Typhimurium (29.14%, 95% CI: 0.0202−0.6571) and S. Enteritidis (21.06%, 95% CI: 0.0181−0.4872). High resistance rates were noted for antimicrobials like erythromycin (60.70%, 95% CI: 0.0000−1.0000) and amoxicillin (39.92%, 95% CI: 0.0589−0.8020). The most prevalent ARGs were blaTEM (80.23%, 95% CI: 0.5736−0.9692) and parC mutation (66.67%, 95% CI: 0.3213−0.9429). Factors such as pH, water activity, and nutrient content, along with external factors like the quality of irrigation water and prevailing climatic conditions, have significant implications on Salmonella contamination. Nonthermal sterilization technologies, encompassing chlorine dioxide, ozone, and ultraviolet light, are emphasized as efficacious measures to control Salmonella. This review stresses the imperative need to bolster prevention strategies and control measures against Salmonella in retail fresh fruits and vegetables to alleviate related food safety risks.

“…The World Health Organization estimates infections due to non-typhoidal Salmonella enterica to bear the highest burden of foodborne diseases, with 180 million diarrheal cases, and Africa and South East Asia were identified as the largest exposed regions [4,5]. Diseases and outbreaks are mostly attributed to contaminated vegetables, meats, drinks, and animal exposure [6][7][8][9]. In Taiwan, non-typhoidal Salmonella is still a prevalent pathogen [10] which causes the highest annual incidence of bacteremia among the population in the South [11].…”

Correlation between Pathogenic Determinants Associated with Clinically Isolated Non-Typhoidal Salmonella

Non-typhoidal and Typhoidal Salmonella are bacterial pathogens source of worldwide and major disease burden. Virulent determinants of specific serovars belonging to non-typhoidal Salmonella have been extensively studied in different models, yet the pathogenesis of this group of bacteria and the development of clinical symptoms globally remains underexplored. Herein, we implemented microbiological and molecular procedures to investigate isolate virulence traits and molecular diversity, likely in association with disease severity. Our results show that selected clinical isolates from a tertiary referring hospital, depending on the richness of the environment and isolate serotypes, exhibited different, and sometimes controversial, virulence properties. The tested strains were susceptible to Ceftriaxone (90%) with decreasing reactivity to Trimethoprim–Sulfamethoxazole (72%), Chloramphenicol (64%), Ampicillin (48%), Gentamicin (44%), and Ciprofloxacin (2%). Disc susceptibility results partially correlated with minimum inhibitory concentration (MIC); however, special attention must be given to antimicrobial treatment, as a rise in multi-resistant isolates to Trimethoprim–Sulfamethoxazole (2/38 µg/mL), Minocycline (8 µg/mL) and Ampicillin (16 µg/mL) has been noticed, with two isolates resistant to Ceftazidime (16 µg/mL). By comparison to previous molecular epidemiology studies, the variation in the gene profiles of endemic pathogens supports the need for continuous and up-to-date microbiological and molecular reports.
