The mitigation of vibriosis in shrimp culture could be accomplished by reducing the virulence of the pathogen or by increasing the immune response of the shrimp. This study aims to evaluate the application of a biofloc system in protecting Pacific white shrimp (Penaeus vannamei) from pathogenic Vibrio parahaemolyticus infection.

We developed a short-time treatment to inactivate Xanthomonas campestris and Salmonella enterica on cabbage, chili pepper, and radish seeds by a combination of chlorine dioxide (ClO2) gas and heat. ClO2 gas was evaporated from a mixed solution which contained hydrochloric acid (1 N) and sodium chlorite (100,000 ppm) (ClO2 solution).

The present study monitored pesticide residues in 2319 samples of fruiting vegetables namely, tomato (416), capsicum (363), brinjal (448), and cucurbits (1,092) grown in the Northern and Western regions of India. The samples were extracted using QuEChERS method and analyzed for the residues of 155 multi–class pesticides by gas chromatography–mass spectrometry and/or liquid chromatography–tandem mass spectrometry.

An analytical method in pomegranate whole fruits and arils was developed in LC-MS/MS and validated as per SANTE/12682/2019. Samples were extracted following acetonitrile-based modified QuEChERS protocol. The method was linear and the coefficient of determination ranged between 0.998 to 0.999. Through this method, all the pesticides were detected and quantified at 10 µg kg-1.

Patulin is a mycotoxin produced by a variety of molds that is found in various food products. The adverse health effects associated with exposure to patulin has led to many investigations into the biological basis driving the toxicity of patulin. Nevertheless, the mechanisms through which mammalian cells resists patulin-mediated toxicity is poorly understood. Here, we show that loss of the Nrf1 transcription factor renders cells sensitive to the acute cytotoxic effects of patulin.

Vibrio fluvialis is an emerging foodborne pathogen that causes severe infections. Serotyping based on surface polysaccharide antigens is important for the clinical detection and epidemiological surveillance of pathogens such as V. fluvialis. For example, variation of the O-antigen, which is highly polymorphic and is responsible for the majority of antigenic variability on the bacterial cell surface, provides the basis for serotyping of Gram-negative bacteria.

Arsenic (As) is a toxic metalloid exist ubiquitously in environment. Epidemiological studies and laboratory animal studies have verified that As damages multiple organs or tissues in the body and is associated with a variety of diseases.

Melatonin is a well-known signaling molecule that mediates a range of physiological activities and various stress reactions in plants.

Cadmium (Cd) is one of the most hazardous heavy metals that negatively affect the growth and yield of wheat. He-Ne laser irradiation is known to ameliorate cadmium (Cd) stress in wheat. However, the underlying mechanism of He-Ne laser irradiation on protecting wheat against Cd stress is not well recognized. In present study, Cd-treated wheat showed significant reduction in growth, root morphology and total chlorophyll content, but notably increase of Cd accumulation in both roots and shoots.

Exposure to environmental pollutants, including dioxin-like pollutants, can cause numerous health issues. A common exposure route to pollutants is through contaminated foods, and thus the gastrointestinal system and gut microbiota are often exposed to high amounts of pollutants.

Chronic hepatitis (CH) in dogs is histologically characterized by an inflammatory infiltration of the liver accompanied by hepatocellular apoptosis or necrosis, varying degrees of fibrosis and regeneration. Oxidative stress has been suggested to play a role in the pathog

Mycotoxin contamination is a leading cause of food spoilage and waste on a global scale. Patulin, a mycotoxin produced by Penicillium spp. during postharvest pome fruit decay, causes acute and chronic effects in humans, withstands pasteurization, and is not eliminated by fermentation. While much is known about the impact of patulin on human health, there are significant knowledge gaps concerning the effect of patulin during postharvest fruit–pathogen interactions.

Karyopherins are involved in transport through nuclear pore complexes. Karyopherins are necessary for nuclear import and export pathways and bind to their cargos. Polyadenylation of messenger RNA (mRNA) is necessary for various biological processes, regulating gene expression in eukaryotes. Until now, the association of karyopherin with mRNA polyadenylation has been less understood in plant pathogenic fungi.

The effects of sumac, cumin, black pepper and red pepper diethyl ether extracts on the growth of eight foodborne pathogens (FBP) and their biogenic amine (BA) production were investigated in histidine decarboxylase broth. The antimicrobial effect was determined by the minimum inhibitory (MIC) and minimum bactericidal (MBC) concentrations. Sumac extract showed the highest antimicrobial activity against FBP.

The objective of this study was to clarify the antibacterial activity and mechanism of Chrysanthemum buds' crude extract (CBCE) against Salmonella Typhimurium, and explore the potential application in cooked chicken.

International Journal of Food Science & Technology, EarlyView. Cronobacter sakazakii could enter a growth-arrested state when exposed to ampicillin. Growth-arrested bacteria can become more tolerant to a wide range of antibiotics, posing a serious threat to food safety and human health. The aim of this study was to investigate the tolerance of growth-arrested C.

Norovirus (NoV) foodborne illness reduction continues to be a focus for the food safety community.  Using a previously published quantitative risk assessment model (Duret et al ., 2017. Risk Anal. , 37:2080-2106), we evaluated more than sixty scenarios examining the impact of compliance and implementation of risk management strategies identified in the FDA Food Code associated with (a) surface cleaning/sanitizing; (b) hand hygiene; (c) exclusion; and (d) restriction.

The traffic of international animal products can be public health hazard when legal import sanitary procedures are not followed. In Brazil, due to its extensive border area, the importation of animal products is a common practice in many areas of the country, especially in Rio Grande do Sul (RS), a state that borders Argentina and Uruguay.

Here we characterized the distribution and the antibiotic resistance of staphylococci from a Brazilian pork production chain. Samples (n = 1,114) from pig farms, pig lots and slaughterhouses, located in two Brazilian states (Minas Gerais and Paraná), were subjected to coagulase-positive Staphylococcus (CPS) enumeration. S.

A quantitative multi-class multi-residue analytical method was developed for the determination of veterinary drugs in milk by high-performance liquid chromatography – tandem mass spectrometry (HPLC-MS/MS).

Effects of iron and sulfur redox states in the soil caused by different growth seasons on Cd uptake by rice remain unclear. In this study, three early rice cultivars and three late rice cultivars were cultivated in a double-cropping system in Cd-contaminated paddy fields.

Arsenic (As), an environmental pollutant, is a highly poisonous metalloid. Accumulated evidence has shown the association between As exposure and elevated risk of the development of coronary heart disease (CHD). Calycosin, a beneficial flavonoid, has demonstrated cardioprotective activities, including those against CHD, in preclinical studies. The anti-As-related CHD activity and mechanism of calycosin have not yet been elucidated.

In order to prevent food-borne diseases caused by Listeria monocytogenes (L. monocytogenes) safely and effectively, plant essential oils that have no toxic side effects and are not prone to drug resistance have become the focus of research. This article takes basil (Ocimum basilicum L.) essential oil (BEO) as the research object and explores its antibacterial mechanism against L. monocytogenes.

Vibrio vulnificus is a marine zoonotic pathogen associated with fish farms that is considered a biomarker of climate change. Zoonotic strains trigger a rapid death of their susceptible hosts (fish or humans) by septicemia that has been linked to a cytokine storm in mice. Therefore, we hypothesize that V. vulnificus also causes fish death by triggering a cytokine storm in which red blood cells (RBCs), as nucleated cells in fish, could play an active role.

Antimicrobial resistance (AMR) represents an increasing issue worldwide, spreading not only in humans and farmed animals but also in wildlife. One of the most relevant problems is represented by Extended-Spectrum Beta-Lactamases (ESβLs) producing Escherichia coli because they are the cause of important infections in human.
