Recent outbreaks linked to contaminated leafy greens underline the need for identifying effective natural approaches to improve produce safety at pre-harvest level. Lactic acid bacteria (LAB) have been evaluated as biocontrol agents in food products.

The aim of this study was to develop a mathematical model describing the survival of Escherichia coli O157:H7 in carrot juice treated with Thymbra capitata essential oil combined with mild heat treatment and stored at different temperatures. The viable count method was used to investigate the effect of the treatment on bacterial survival, and the response surface methodology was used to develop a statistical model fitting the data.

Escherichia coli O157:H7 is a pathogen that commonly causes foodborne illness and represents a health hazard to consumers. The combined use of synergistic antimicrobial peptides (AMPs) is a promising way to improve the microbiological safety of foods. In this study, we detected the synergistic interactions between thanatin and BF-15a3 to reduce their usage and obtain more efficient antibacterial activity.

Escherichia coli O157:H7 is a foodborne pathogen that has become a serious global concern for food safety. Despite the application of different traditional biocontrol methods in the food industry, food borne disease outbreaks linked to this organism remain. Due to their high specificity, lytic bacteriophages are promising antimicrobial agents that could be utilized to control pathogens in foods.

Escherichia coli O104:H4 strain 11-3088 encoding Stx2a is epidemiologically related to the foodborne outbreak associated with sprouts in Germany, 2011. Sprouting provides suitable conditions for bacterial growth and may lead to transduction of non-pathogenic strains of E. coli with Stx phages. Although transduction of E. coli by Stx phages in food has been documented, data on the phages from E. coli O104:H4 is limited.

Escherichia coli O157 belongs to a diverse serogroup including different H serotypes. E. coli O157: H7 is the most common serotype that can cause acute gastroenteritis, hemorrhagic colitis (HC), and hemolytic-uremic syndrome (HUS) in humans. In recent years, some E. coli O157:non-H7 strains have been reported to cause sporadic cases and outbreaks of diarrheal diseases. However, the phenotypic and genotypic characteristics of E.

Escherichia coli O157:H7 (E. coli O157) is still one of the main pathogenic strains causing food poisoning. Here in, we established a strategy that can simultaneously remove free E. coli O157 and the biofilms it forms. Composite nanofiber (fP-NF) films were synthesized successfully by co-encapsulating E.

Shiga toxin-producing Escherichia coli and Salmonella enterica are important pathogens worldwide. Bacteriophages can be effectively used to reduce the incidence of foodborne pathogens. The host recognition systems of phages are highly specific, with the host range of a common phage being limited to the species or strain level. Here, we characterized a novel broad-host-range phage, EscoHU1, that infects several bacterial species, including E.

The following reports on the generation of hydroxyl-radical activated water prepared by passing a hydrogen peroxide solution containing Fe(III) catalyst through a UV-C reactor. The activated water was subsequently evaluated for antimicrobial activity against Escherichia coli O157:H7 in suspension or when inoculated onto mung beans.

Phebus Foodborne pathogens like Salmonella and Escherichia coli O121 can endure the harsh low water activity (aw) environment of wheat flour for elongated periods of time and can proliferate when hydrated for baking or other purposes.
