TLDR
In this paper, the prevalence, persistence and ecology of four major foodborne pathogens, Shiga toxin-producing Escherichia coli (STEC), Salmonella, Campylobacter and closely related Arcobacter, and Listeria monocytogenes, in water are discussed.Abstract:
Water is vital to agriculture. It is essential that the water used for the production of fresh produce commodities be safe. Microbial pathogens are able to survive for extended periods of time in water. It is critical to understand their biology and ecology in this ecosystem in order to develop better mitigation strategies for farmers who grow these food crops. In this review the prevalence, persistence and ecology of four major foodborne pathogens, Shiga toxin-producing Escherichia coli (STEC), Salmonella, Campylobacter and closely related Arcobacter, and Listeria monocytogenes, in water are discussed. These pathogens have been linked to fresh produce outbreaks, some with devastating consequences, where, in a few cases, the contamination event has been traced to water used for crop production or post-harvest activities. In addition, antimicrobial resistance, methods improvements, including the role of genomics in aiding in the understanding of these pathogens, are discussed. Finally, global initiatives to improve our knowledge base of these pathogens around the world are touched upon.read more

Photoinactivation of Phage Phi6 as a SARS-CoV-2 Model in Wastewater: Evidence of Efficacy and Safety
Marta Gomes,Maria Bartolomeu,Cátia Sofia Silva Vieira,Ana T. P. C. Gomes,Maria A. F. Faustino,Maria G. P. M. S. Neves,Adelaide Almeida +6 more
TL;DR: PDI proved to be an efficient approach in the inactivation of the viruses, and the PDI-treated effluent showed no toxicity to native aquatic microorganisms under realistic dilution conditions, thus endorsing PDI as an efficient and safe tertiary WW disinfection method.

Enterohemorrhagic Escherichia coli and a Fresh View on Shiga Toxin-Binding Glycosphingolipids of Primary Human Kidney and Colon Epithelial Cells and Their Toxin Susceptibility
TL;DR: The high and extremely low susceptibility of primary renal and colonic epithelial cells, respectively, are suggested, suggesting a large resilience of the intestinal epithelium against the human-pathogenic Stx1a- and Stx2a-subtypes due to the low content of the high-affinity Stx-receptor Gb3Cer in colon epithel cells.

Current methodologies and future direction of Campylobacter isolation and detection from food matrices, clinical samples, and the agricultural environment.
TL;DR: In this article , a review of the existing variability in Campylobacter enrichment and isolation procedures used by researchers and regulatory agencies worldwide, for various matrices, is presented, where the challenges associated with developing and validating new culture, molecular, and immunological methods for rapid and sensitive campylobacteria detection are discussed.

TL;DR: To estimate the global burden of nontyphoidal Salmonella gastroenteritis, existing data from laboratory-based surveillance and special studies were synthesized, with a hierarchical preference to prospective population-based studies, "multiplier studies," disease notifications, returning traveler data, and extrapolation.

Escherichia coli that Cause Diarrhea: Enterotoxigenic, Enteropathogenic, Enteroinvasive, Enterohemorrhagic, and Enteroadherent
TL;DR: There are four major categories of diarrheagenic Escherichia coli: enterotoxigenic (a major cause of travelers' diarrhea and infant diarrhea in less-developed countries), enteroinvasive (a cause of dysentery), enteropathogenic (an important cause of infant diarrhea), and enterohemorrhagic ( a cause of hemorrhagic colitis and hemolytic uremic syndrome).
