Summary: We investigated the antimicrobial activity of sertraline against Listeria monocytogenes, and its effects on biofilm formation and virulence gene expression. Sertraline showed inhibitory effects on L. monocytogenes at concentrations between 16-32 μg/mL and a bactericidal effect at 64 μg/mL. Sertraline damaged the cell membrane, decreased ATP and intracellular pH, and reduced biofilm formation efficiency. Importantly, low concentrations of sertraline down-regulated the expression of various virulence genes in L. monocytogenes.

Summary: Listeria monocytogenes is an important food-borne pathogen that can contaminate food. Traditional methods to inhibit its growth and extend food shelf life often damage food quality. Probiotics, as a biological antimicrobial method, have shown promise in effectively inhibiting the growth of L. monocytogenes. This review summarizes human listeriosis, current contamination situations, and discusses the effects and mechanisms of probiotics in inhibiting L. monocytogenes in foods. The latest applications of probiotics in dairy, meat, and fresh products are also presented and discussed.

Summary: This study investigated the prevalence, serotype, antimicrobial resistance, virulence potential, and biofilm formation of Listeria monocytogenes isolated in Japan in 2022. The results showed a significantly lower prevalence rate compared to previous years, as well as reduced antimicrobial resistance and weaker biofilm formation. However, the presence of virulent L. monocytogenes contamination in food should still be acknowledged.

Summary: Listeria monocytogenes is a foodborne pathogen that can form biofilms on various surfaces and express different genes in biofilm and planktonic cells, which could affect its stress tolerance and virulence. This study investigated the expression of ten key stress response and/or virulence-related genes in three different strains of L. monocytogenes and found strain-dependent differential gene expression between biofilm and planktonic cells, suggesting the importance of considering strain variability in studies and eradication methods of pathogenic biofilms.

Summary: We investigated the prevalence, genetic diversity, and antibiogram profiles of Listeria monocytogenes (Lm) in fruits and vegetables sourced from three District Municipalities in the Eastern Cape Province, South Africa. Lm was detected in a significant proportion of the samples tested, with high genetic diversity and multidrug resistance. This highlights the potential threat to consumers and the importance of food safety measures.

Summary: Genomic diversity of Listeria monocytogenes isolates from deboning and slicing areas in three dry-cured ham processing plants was analyzed. Different serogroups, pulsotypes, and sequence types were identified, along with premature stop codons associated with attenuated virulence and features related to biofilm formation and increased tolerance to compounds. The study suggests the need for control measures and cleaning protocols to eliminate the pathogen effectively in the processing environment.

Summary: This study demonstrates the potential of Litsea cubeba essential oil (LC-EO) and its main component, citral, as anti-virulence agents targeting listeriolysin O (LLO) of Listeria monocytogenes. The results show that citral can significantly decrease the hemolytic activity of LLO by inducing conformational changes and forming covalent bonds with specific residues. This research provides a new approach for the development of LLO-targeting anti-virulence agents and expands the application of LC-EO in food microbiological safety.

Summary: Food safety and quality are increasingly important in our society, driving the development of novel optical food sensing technologies. However, current optical sensing technologies are often limited in their sensitivity and product variability. In this study, we developed a novel pistachio nut screening methodology using fluorescence spectroscopy and advanced chemometrics to simultaneously detect shells, tree parts, and aflatoxins. By optimizing hardware and software parameters, we achieved a high classification accuracy for healthy pistachio kernels.

Summary: This study used bibliometric visualisation map analysis to explore the publication outputs, trends, and hotspots for endocrine disruptors (EDMs) biosensor development in relation to mycotoxins. The analysis showed that the current literature primarily focuses on developing biosensors for detecting highly toxic and widely distributed mycotoxins in food, but there needs to be more focus on biosensors for detecting mycotoxins known as endocrine disruptors.

Summary: Polycyclic aromatic hydrocarbons (PAHs) are a major cause of human cancer. This study developed a quantitative analysis method for PAH4 using the back propagation neural network (BPNN) algorithm and constant wavelength synchronous fluorescence (CWSF) spectra as the data sets. The method can predict the concentrations of PAH4 in edible oil samples without preprocessing or pre-separation. It has been proven to be a powerful tool for the rapid detection of PAH4.

Summary: Food spoilage is primarily caused by microbial contamination. Curcumin has shown moderate antimicrobial activity as a food preservative. This study formulates curcumin with zinc acetate to enhance its efficacy, resulting in Cur-Zn with increased antimicrobial activity against multiple food-contaminating bacteria and fungi. With light illumination, the antimicrobial activity of Cur-Zn is further enhanced due to the photodynamic inactivation (PDI) effect.
