“…Thus, STEC is routinely associated with multiple other bacterial species to form complex biofilms in processing plants [175,176]. Food acids, such as sodium acid sulfate and nonionic surfactants called polysorbates, have been utilized to slow down STEC transmission by slowing the biofilm formation of various STEC serotypes [211,212]. Natural products including plant secondary metabolites-such as flavonoids, terpenes, and essential oils-have been employed to inhibit biofilm formation in STEC [213].…”

Shiga-toxin-producing Escherichia coli (STEC) is a food-borne pathogen that causes human gastrointestinal infections across the globe, leading to kidney failure or even death in severe cases. E. coli are commensal members of humans and animals’ (cattle, bison, and pigs) guts, however, may acquire Shiga-toxin-encoded phages. This acquisition or colonization by STEC may lead to dysbiosis in the intestinal microbial community of the host. Wildlife and livestock animals can be asymptomatically colonized by STEC, leading to pathogen shedding and transmission. Furthermore, there has been a steady uptick in new STEC variants representing various serotypes. These, along with hybrids of other pathogenic E. coli (UPEC and ExPEC), are of serious concern, especially when they possess enhanced antimicrobial resistance, biofilm formation, etc. Recent studies have reported these in the livestock and food industry with minimal focus on wildlife. Disturbed natural habitats and changing climates are increasingly creating wildlife reservoirs of these pathogens, leading to a rise in zoonotic infections. Therefore, this review comprehensively surveyed studies on STEC prevalence in livestock and wildlife hosts. We further present important microbial and environmental factors contributing to STEC spread as well as infections. Finally, we delve into potential strategies for limiting STEC shedding and transmission.

“…The medium cultured with bacterial strains (without PPLs treatment) was used as positive control, whereas the medium without bacterial culture was used as negative control. The recommended dose of chlorine (200 ppm, Weerarathne et al, 2021) for food contact surfaces was also used for comparison of the results obtained with PPL extracts. The antibiofilm efficiencies of the PPLs were calculated as described by Pitts et al (2003):…”

In this study, the antibacterial and antibiofilm properties of pomegranate (Punica granatum L.) extracts (PPLs) prepared by 10g of pomegranate peels (PPL10) and 100 mL of different solvents (ethanol, methanol, and their acid combinations, and water) were investigated as sources of bioactive compounds against food related bacteria. The antimicrobial activities of the extracts were measured by using agar well diffusion assay. The acid-treated extracts exhibited the highest antimicrobial activities (31-34 mm). The biofilm formations were assessed by using a microplate reader (570 nm) after crystal violet staining. The prevention and removal of bacterial biofilms were also evaluated by using extracts prepared by 5g of initial pomegranate peel (PPL5) with the different solvents or 200 ppm chlorine solution. All PPL5 and PPL10 extracts diluted at different ratios inhibited and removed biofilms and the highest antibiofilm effects were up to 80% by acidtreated extracts. In addition, PPL5s and PPL10s were as effective as or more effective than chlorine for the prevention of biofilms. Therefore, from an economical perspective the PPL5s could represent promising candidates as natural antibiofilm agents for food industry.

“…The Environmental Protection Agency of the United States has also recently designated SBS as a “Safer Choice” antimicrobial and processing aid or additive (EPA, 2020). SBS has a pKa of 1.99 (Weerarathne et al, 2021), and shows acidity like phosphoric acid (Pszczola, 2007). In its role as a potential antimicrobial wash solution, research has showcased its efficacy in reducing E. coli O157:H7, L. monocytogenes , and S. Enteritidis on whole chicken drumsticks (Bodie et al, 2019; Dittoe et al, 2019; Weerarathne et al, 2021).…”

Background and ObjectivesIn the last decade, the incidence of foodborne illness outbreaks and recalls connected with wheat flour and flour‐based goods infected with enteric bacteria such as Salmonella has grown. This study investigated the activity of sodium bisulfate (SBS) as an antibacterial agent against four different serovars of Salmonella enterica.FindingsThe dose‐dependent, anti‐Salmonella concentration of SBS revealed a minimum inhibitory activity (MIC) of 0.32%. At this concentration, SBS induced the production of reactive oxygen species (ROS) demonstrating that lysis of bacterial cells has occurred. SBS tempering (1.5% SBS, w/v) reduced wheat Salmonella load by 4.3 log CFU/g after 24h of tempering. Additionally, tempering at 0% (control) and 1.5% SBS (17% moisture, 24 h) showed similar (p > 0.05) flour functionality (rheology and composition) and baking characteristics (volume, texture, and crumb structure).ConclusionThese results suggest that SBS is a viable antibacterial tempering agent to reduce Salmonella contamination in wheat before milling.Significance and noveltyAcidic water tempering, as opposed to the traditional water tempering method, may result in milled products with improved microbiological quality.This article is protected by copyright.
