Hepatitis E virus (HEV) is an emerging zoonotic pathogen that exhibits great host diversity. The primary means of transmission of the virus in low- and middle-income countries is contaminated water, often due to a lack of access to proper sanitation, which leads to faecal contamination of water sources. Environmental surveillance is an important tool that can be used to monitor virus circulation and as an early warning system for outbreaks.

A novel loop‐mediated isothermal amplification assay was established on the basis of screening and verification of detection targets for rapid detection of Staphylococcus aureus. After amplification, there are two distinct methodologies for result determination: one involves the analysis of fluorescence curves, while the other involves the observation of color changes.

This research study the effect of the food product, even present in trace in the bacteria's habitat, on the bacteria potential of biofilm formation. Understanding the conditions that favor or disadvantage the formation of biofilms could help in the development and implementation of new alternative strategies to combat food‐borne infections.

An LED UV curing system (wavelength: 278 nm) was used to effectively reduce AFB1, AFB2 and AFG1. Meanwhile, possible UV degradation mechanisms of AFB2 and AFG1 were further clarified. More importantly, the LED UV curing system had a good aflatoxins detoxification effect in crops. Summary Aflatoxins (AFs) are highly toxic and cancer‐causing compounds, which could be commonly found in agricultural products and feeds.

A nano photocatalyst rGO/TiO2 was modified by sol–gel‐irradiation method and used to degrade the deoxynivalenol in liquid. The photocatalytic degradation mechanism of rGO/TiO2 was also researched. Summary The rGO/TiO2 nanocomposite photocatalyst was synthesised using the sol–gel‐irradiation way to efficiently remove deoxynivalenol (DON) for the grains product's safety and quality.

Abstract This study investigated the disparities in soil characteristics and pathogenic bacteria prevalence between shrimp ponds affected by acute hepatopancreatic necrosis disease (AHPND) and unaffected ponds, alongside examining the spatial distribution of soil attributes in flat‐oriented pond soil strata.

Unravelling the ‘Quadruple Whammy’: This research delves into the profound impact of Brexit, COVID‐19, conflicts and natural disasters on the European food supply chain. Analysing challenges and proposing strategies, it emphasises the imperative form of resilience and proactive planning in the face of unprecedented disruptions.

Kefir is a fermented dairy product based on the fermentation of milk by bacteria and yeasts. It is produced by adding kefir grains, consisting of a consortium of microorganisms, to milk in order to start a natural fermentation (Garofalo et al., 2020).

Campylobacter jejuni represents one of the leading causes of bacterial gastroenteritis in humans and is primarily linked to chicken meat contamination. In the present study, we analyzed the virulence and survival genes, antimicrobial resistance, and the clonal distribution of 50 C. jejuni isolates obtained from various sources in 14 chicken slaughterhouses across 8 provinces in South Korea from 2019 to 2022.

Salmonella enterica serovar Typhimurium (S. Typhimurium), a foodborne pathogen that poses significant public health risks to humans and animals, presents a formidable challenge due to its antibiotic resistance. This study explores the potential of Lactobacillus acidophilus (L. acidophilus 1.3251) probiotics as an alternative strategy to combat antibiotic resistance associated with S. Typhimurium infection.

Mycotoxins enter the cheese chain through unwanted mould growth, either directly in the cheese or indirectly in the milk through feed contamination. Exposure to mycotoxins can have serious consequences for human health. Our analysis of recent studies showed that cheese retains a significant percentage of AFM1 and OTA found in cow's milk, as well as two major mycotoxins, ROQ‐C and MPA, during the cheese ripening phase.

Abstract Background Including seaweed in cattle feed has gained increased interest, but it is important to take into account that the concentration of toxic metals, especially arsenic, is high in seaweed. This study investigated the arsenic species in milk from seaweed‐fed cows.

Lanzhou lily (Lilium davidii var. willmottiae) is an exclusive sweet lily variety indigenous to China, which is susceptible to bulbous rot caused by fungal infection during storage. This experiment tests the pathogenicity of the pure culture isolated from the diseased tissue was confirmed in accordance with Koch's postulates, and the pathomycetes were identified based on their morphological and molecular characteristics.

BackgroundIt is essential to consider a practical antibody test to successfully implement marker vaccines and validate vaccination efficacy against classical swine fever virus (CSFV). The test should include a serological antibody assay, combined with a tool for differentiating infected from vaccinated animals (DIVA).

Chronic hepatitis B, a major cause of liver disease and cancer, affects >250 million people worldwide. Currently there is no cure, only suppressive therapies. Efforts to develop finite curative hepatitis B virus (HBV) therapies are underway, consisting of combinations of multiple novel agents with or without nucleos(t)ide reverse-transcriptase inhibitors.

Summary Fusarium head blight (FHB) and the presence of mycotoxin deoxynivalenol (DON) pose serious threats to wheat production and food safety worldwide. DON, as a virulence factor, is crucial for the spread of FHB pathogens on plants. However, germplasm resources that are naturally resistant to DON and DON‐producing FHB pathogens are inadequate in plants.

Campylobacter jejuni (C. jejuni) is a common pathogen that often causes diarrhea, loss of appetite, and even enteritis in domestic cats, affecting their growth and development, especially in kittens under 6 months of age. Oral passive immunization with chicken yolk antibody Y has been proved effective for the treatment of gastrointestinal pathogen infections due to its high specificity. In this study, C.

Abstract

The wheat head blight disease caused by Fusarium graminearum is a major concern for food security and the health of both humans and animals. As a pathogenic microorganism, F. graminearum produces virulence factors during infection to increase pathogenicity, including various macromolecular and small molecular compounds. Among these virulence factors, secreted proteins and deoxynivalenol (DON) are important weapons for the expansion and colonization of F. graminearum.
