Decontamination of egg‐associated pathogens using plasma‐activated water and plasma‐activated hydrogen peroxide, along with examining their characteristics and effects on egg quality. Abstract This study investigated the effectiveness of plasma‐activated water (PAW) and plasma‐activated hydrogen peroxide (PAHP) in reducing egg‐associated pathogens.

Graphıcal Abstract The antimicrobial activity of eugenol against Campylobacter jejuni in a food model system. Abstract Campylobacter jejuni is the predominant bacterial cause of gastroenteritis, the main cause of foodborne deaths. Currently, Campylobacter is a common foodborne pathogen found in poultry; thus, there is a need for the development of novel intervention strategies. The aim of the study was to examine the effect of eugenol on C. jejuni load in an experimental chicken meat model.

In this study, Campylobacter jejuni survival in raw milk was investigated taken into consideration colony-forming units (CFUs) and VBNC cells. CFU from two different strains of C.

ComBase data can be used to develop and validate models and to test novel modeling methods like artificial neural networks (ANN) and acceptable prediction zones (APZ), which have been shown to outperform traditional methods.

Journal of Food Safety, EarlyView. Campylobacter frequently contaminates chicken. Trisodium phosphate (TSP) is used for chicken decontamination; however, reduction of chemical preservatives is desirable. This study analyzed the efficacy of two commercial citrus-based products (CitroSan [CS] and Citrol-K Ultra [CK]) alone and in combination with TSP for reduction of Campylobacter in vitro and in chicken.

Campylobacter is the most common cause of bacterial gastroenteritis worldwide and the most frequently reported foodborne pathogen in the European Union (EU). The predominant source of infection is poultry. The reduction of Campylobacter spp. in the poultry meat chain in the EU can only be achieved with an integrated meat safety assurance approach.

The present study investigated the effects of combined ultrasound (37 kHz, 380 W for 5 min) and peroxyacetic acid (PAA; 50–200 ppm) treatment on the reduction of Salmonella Typhimurium and Campylobacter jejuni on chicken skin. Ultrasound was not sufficient to inactivate S. Typhimurium (0.48 log CFU/g reduction) or C. jejuni (0.25 log CFU/g reduction), whereas PAA significantly (p < .05) reduced S. Typhimurium (0.93–1.59 log CFU/g reduction) and C. jejuni (0.77–1.52 log CFU/g reduction).

A newly isolated Campylobacter jejuni bacteriophage CJ01 was partially characterized and might be a potential biocontrol agent to improve food safety. Abstract Campylobacter jejuni is a major foodborne pathogen causing acute bacterial enteritis worldwide. Screening of novel bacteriophages as biocontrol tools to eliminate C. jejuni in food during pre‐ and postharvest is an emerging research field. In this study, we partially characterized C.

This study investigated the occurrence of shiga toxin‐producing Escherichia coli (STEC), thermotolerant Campylobacter spp. and Salmonella spp. in Swedish dairy milk. A total of 302 inline milk filters were analyzed. Salmonella was not isolated from any filters. Polymerase chain reaction screening detected thermotolerant Campylobacter in 30.5% of the milk filters analyzed and it was isolated from 12.6% of filters.

Abstract

Campylobacter have been found in lymphoid tissue of poultry, but the location in these tissues has not been determined. The objective of this study was to determine if Campylobacter are on the outside or on the inside of the spleen. For external (ES) spleen sampling 2 days post-inoculation, each spleen was rinsed with 3 mL of Bolton's enrichment broth (BEB). For internal (IS) spleen sampling, each rinsed spleen was submerged into 70% ethanol for 10 s, removed and submerged into 0.85% saline.
