This study optimized storage conditions for fermented pork jerky via microbial fermentation. Lactobacillus bulogaricus was employed as starter culture, fermentation conditions and baking conditions were optimized in study. Microbial indices reflecting parameters of preserved fermented pork jerky involved the detection of total plate count, Escherichia coli, Salmonella, Staphylococcus aureus and Shigella.

Managing the presence of Salmonella in ground beef has been an ongoing challenge for the beef industry. Salmonella prevalence can vary regionally, seasonally, and within the animal, making intervention development difficult. The objective of this study was to assess the efficacy of an autogenous Salmonella vaccine in mitigating Salmonella in lymph nodes (LNs) of feedlot cattle. An autogenous vaccine was developed using the most common salmonellae serovars ( S. Kentucky, S. Anatum, S.

The lack of hygiene and sanitation practices and insufficient infrastructure in Cambodian informal markets may increase the risk of food contamination, specifically raw vegetables, which in turn may increase the chances of contracting a foodborne disease.

• Salmonella enterica subsp.

Bacteriophage OSY-STA is a new anti-Salmonella phage that was isolated from a chicken farm in Ohio. It is a promising candidate for food safety applications, considering its efficiency in infecting several Salmonella enterica serovars. The current work presents its genomic characteristics. Salmonella phage OSY-STA has a 111,039-bp genome and 166 open reading frames.

The complete genome sequences of 12 isolates of the rare Salmonella enterica serovar Adjame were determined by combining Nanopore and Illumina sequence reads. Chromosome sizes ranged from 4,597,011 bp to 4,678,052 bp, and the GC content was 52.3%. A virulent plasmid of 87,433 bp was found in only one isolate.

Mucosal-associated invariant T (MAIT) cells are innate T lymphocytes activated by bacteria that produce vitamin B2 metabolites. Mouse models of infection have demonstrated a role for MAIT cells in antimicrobial defense. However, proposed protective roles of MAIT cells in human infections remain unproven and clinical conditions associated with selective absence...

Salmonella Weltevreden is increasingly reported from aquatic environments, seafood, and patients in several Southeast Asian countries. Using genome-wide analysis, we characterized S. Weltevreden isolated from cultured shrimp and tilapia from Vietnam and China to study their genetic characteristics and relatedness to clinical isolates of S. Weltevreden ST-365.

ABSTRACT

Colistin is an important antibiotic currently used to manage infections caused by multidrug-resistant pathogens in both humans and livestock animals. A new mobile colistin-resistance (mcr-9) gene was recently discovered; this discovery highlighted the need for rigorous monitoring of bacterial resistance against colistin.

In Japan, strategies for ensuring food safety have been developed without reliable scientific evidence on the relation between foodborne infections and foods. The aim of this research was to provide information on the proportions of foodborne diseases caused by seven major causative pathogens ( Campylobacte r spp., Salmonella spp., EHEC, V. parahaemolyticus , Clostridium perfringens , Staphylococcus aureus , and Norovirus) attributable to foods using analysis of outbreak surveillance data.

Salmonella is an important foodborne pathogen that causes public health problem globally, and chicken meat is considered as an important reservoir of Salmonella dissemination to humans. Furthermore, the increase of antimicrobial resistance (AMR) in Salmonella has intensified the problem.

As demand for fresh-cut produce increases, minimizing the risk of salmonellosis becomes critical for the produce industry. Sanitizers are routinely used during commercial flume washing of fresh-cut produce to minimize cross-contamination from the wash water .

Salmonella is a highly diverse genus consisting of over 2,600 serovars responsible for high-burden food- and waterborne gastroenteritis worldwide. Sensitivity and specificity of PCR-based culture-independent diagnostic testing (CIDT) systems for Salmonella, which depend on a highly conserved gene target, can be affected by single nucleotide polymorphisms (SNPs), indels, and genomic rearrangements within primer and probe sequences.

The Food Safety Modernization Act (FSMA) includes a time-to-harvest interval following the application of noncompliant water to preharvest produce to allow for microbial die-off. However, additional scientific evidence is needed to support this rule. This study aimed to determine the impact of weather on the die-off rate of Escherichia coli and Salmonella on spinach and lettuce under field conditions.
