Ochratoxin A (OTA) in food poses a serious challenge to public health. Herein, using the nanobody-driven controllable aggregation of gold nanoparticles (AuNPs) in a glucose oxidase-tyramine-horseradish peroxidase (GOx-TYR-HRP) system, we propose a direct competitive plasmonic enzyme immunoassay (dc-PEIA) for OTA detection.

Background and aims Human health is seriously threatened by cadmium (Cd) and arsenic (As) poisoning in paddy soils. Due to different geochemical behavior, Cd and As are challenging to repair together. We aims to inquire into the influences of zero valent iron (ZVI) and its mixture on acidic Cd-As contaminated paddy soil and reveal the relevant mechanisms.

Background The widespread presence of arsenic (As) and cadmium (Cd) in agricultural soils coupled with a problem of Al phytotoxicity threatens sustainability of agricultural production system as well as natural ecosystems.

Vibrio parahaemolyticus is a common foodborne pathogenic bacterium. With the overuse of antibiotics, an increasing proportion of drug-resistant strains are emerging, which puts enormous pressure on public health. In this study, a V. parahaemolyticus-specific phage, VP41s3, was isolated. The head length, width, and tail length of the phage were 77.7 nm, 72.2 nm, and 17.5 nm, respectively.

Penetration ability is one of the biggest concerns of light-emitting diode (LED) technology in the food industry, as most food matrices are usually in packaged conditions. This study aimed to evaluate the antifungal effects of LEDs on both pure culture and litchi fruit, which are packaged by nine commonly used commercial packaging films. Results showed that LEDs could penetrate these films with more than 88% energy transmittance.

The synergistic effect of multiple mycotoxins in cereals increases their toxicity. Therefore, the simultaneous detection of multiple mycotoxins in cereals is of great importance. Exonuclease III (Exo III) assisted electrochemical aptasensor has been used for mycotoxin detection, but simultaneous detection of two mycotoxins has not been previously reported.

Salmonella enterica subsp. enterica Typhimurium and its monophasic variant I 1;4,[5],12:i:- (MVST) are responsible for thousands of reported cases of salmonellosis each year in Canada, and countries worldwide. We investigated S.

A total of 55 food and clinical S. Schwarzengrund isolates were assayed for plasmid content, among which an IncFIB-IncFIC(FII) fusion plasmid, conferring streptomycin resistance, was detected in 17 isolates. Among the 17 isolates, 9 were food isolates primarily collected from poultry meat, and 8 clinical isolates collected from stool, urine, and gallbladder.

The antibiotics are generally regarded as the first choice approach to treat dairy mastitis, targeting the public health problems associated with the food safety and the emergence of antibioticresistant bacteria. The objective of the study was to evaluate the antibacterial efficacy of ursolic acid (UA) when used to treat Staphylococcus aureus and other isolates associated with bovine mastitis and to clarify the mechanistic basis for these effects.

Rapid growth in commercial poultry production is one of the major sources of Salmonella infections that leads to human salmonellosis. The two main Salmonella enterica serovars associated with human salmonellosis are enteritidis and typhimurium. The aim of this study was to determine the prevalence of S. enterica serovars Enteritidis and S. Typhimurium as well as their Salmonella pathogenicity islands (SPI) and antibiotic resistance profiles in broiler chicken feces from slaughterhouses.

Abstract Acetamiprid is a pesticide active substance with insecticidal action whose approval was renewed by Commission Implementing Regulation (EU) 2018/113. In January 2022, the EFSA PPR Panel published a statement following a request from the European Commission to advise on human health or the environment based on new scientific evidence presented by France during the decision‐making phase.

Dust sprinkling was an effective way to experimentally colonise layer chickens with Salmonella Typhimurium. Salmonella infection with 1000 CFU/g of dust altered the gut microbiota. This model mimics Salmonella infection in the field. Abstract Role of dust in Salmonella transmission on chicken farms is not well characterised.

This research underscored the crucial role of Alcalase and Flavourzyme in generating antibacterial peptides. Certain fractions of mung bean and adzuki bean protein hydrolysates contained bioactive peptides against S. aureus and S. Typhimurium. Interestingly, small cationic peptides containing lysine with an amphipathic nature were a key factor in inhibiting S. aureus.

The microbial quality and safety on two types of unpasteurised juices in Lleida was evaluated. No Salmonella spp., L. monocytogenes, or E. coli were detected. Summary The growing consumption of untreated juices has increased the outbreaks related to Salmonella spp., Escherichia coli O157:H7 and Listeria monocytogenes. Although these pathogens are not in favourable conditions in fruit juices, cases of survival in acidic environments have been reported in fruit and vegetable juices.

by Aaron Embry, Nina S. Baggett, David B. Heisler, Addison White, Maarten F. de Jong, Benjamin L. Kocsis, Diana R. Tomchick, Neal M. Alto, Don B. Gammon Arboviruses are a diverse group of insect-transmitted pathogens that pose global public health challenges.

Cadmium (Cd) is a common environmental pollutant associated with an increased incidence of renal metabolic diseases. Luteolin (Lut), a natural flavonoid, is widely used for its multifaceted therapeutic properties in inflammatory diseases. However, whether Lut protects against Cd-induced nephrotoxicity is still equivocal.

Phenyllactic acid (PLA) as a natural phenolic acid exhibits antibacterial activity against non-spore-forming bacteria, while the inhibitory effect against bacterial spore remained unknown. Herein, this study investigated the inactivation effect of PLA against Bacillus cereus spores. The results revealed that the minimum inhibitory concentration of PLA was 1.25 mg/mL.

The spread of superbugs in dairy products can jeopardize global public health. To date, information on the incidence rates of virulent and β-lactams-resistant (BLR) Salmonella in cheeses from rural areas of Egypt has been lacking. Biochemical, serological, antibiotic susceptibility, and multiplex PCR (M-PCR) tests were performed to identify and characterize Salmonella isolates.

Paralytic shellfish poisoning is an important concern for mollusk fisheries, aquaculture, and public health. In Galicia, NW Iberian Peninsula, such toxicity has been monitored for a long time using mouse bioassay. Therefore, little information exists about the precise toxin analogues and their possible transformations in diverse mollusk species and environments.

The increasing rates of morbidity and mortality owing to bacterial infections, particularly Staphylococcus aureus have necessitated finding solutions to face this issue. Thus, we elucidated the phytochemical constituents and antibacterial potential of Cleome droserifolia extract (CDE).

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.

Background. Excess accumulation of potentially toxic elements in frequently consumed fruits is a serious threat to human health. The aim of this study was to determine the levels of cadmium (Cd), chromium (Cr), copper (Cu), and lead (Pb) and to estimate the noncarcinogenic and carcinogenic health risks associated with their daily intake in commonly consumed fruits in Bahir Dar town, northwest Ethiopia. Methods.

This study aimed to determine the prevalence and serovar distribution of salmonellae in liver, heart, and spleen (LHS) and gizzard (G) of slaughtered broilers. For this, a total of 60 sample units, comprised of 30 LHS and 30 G collected from 3 slaughterhouses, were analysed by reference methods for detection and serotyping as revised ISO 6579-1:2017 and ISO 6579-3:2014, respectively.

Salmonella is a major cause of foodborne diseases worldwide. Conventional rapid assays for detecting Salmonella in real samples often encounter severe matrix interference or detect the limited number of species of a genus, resulting the inaccuracy of detection.
