Concern about the safety of acrylamide in french fries led to the identification of potato varieties low in the acrylamide precursors asparagine and reducing sugars that vary with variety, nitrogen (N) fertilizer applications, and other factors, but produce light‐colored fries, which may not appeal to consumers.

Mycotoxins presence was evaluated in animal feed marketed in Tunisia for the first time ever.

Methicillin‐resistant Staphylococcus aureus (MRSA), a versatile pathogen bearing multiple virulence determinants, is increasingly being detected in various food‐producing animals, including fish. In addition, it is a potential food poisoning agent. MRSA is not an inherent microbiota of fish; its presence is attributed to pre‐ or postharvest contamination through fish handlers, water, ice, and processing equipment.

This article review the emerging trends in the spread, distribution, and epidemiology of Listeria species in foods, water, human, animals, and different environments in the Southern African sub‐region based on the appraisal of scholarly articles available online.

Spot map showing areas of sample collection from Delhi‐NCR. Abstract Fresh fruits and vegetables contaminated with microbial pathogens can cause outbreaks of food poisoning and other enteric diseases if consumed raw. The objective of the present study was to determine the bacterial contamination and antibiotic resistance in fresh produce sold in Delhi, India.

Dendrogram analysis of ERIC& REP fingerprints of ESBL producing Klebsiella pneumoniae isolates. Abstract Klebsiella species have been at the center of attention over the recent years due to its role in the evolution of antimicrobial resistance and is not only associated with nosocomial but also with food related infections worldwide. In this study, out of 336 samples of animal intestinal and foods of animal origin screened, 99 samples were found to harbor Klebsiella spp.

BACKGROUND Heavy metal resistant bacterium Enterobacter sp. C1D was evaluated for cadmium (Cd) mediated exopolysaccharide production, biofilm formation and legume root colonization ability under Cd stress to alleviate metal induced stress. RESULTS The plant was sensitive to Cd (IC50 3‐ 4μg/ml), while the bacterium showed high Cd tolerance (MIC99 120 μg/ml).

Chlorpyrifos is a type of organophosphate insecticide used extensively in the plantation of tomatoes, a worldwide popular food. However, chlorpyrifos residues on tomatoes bring risks to human health considering the consumption level of tomato is relatively high across many countries. Accurate detection and strict regulation of chlorpyrifos residues are very important in controlling health risks related to chlorpyrifos.

Abstract

Background

Arsenic (As) and cadmium (Cd) are two toxic elements that have a relatively high risk of transfer from paddy soil to rice grain. Rice is a major dietary source of these two elements for populations consuming rice as a staple food. Reducing their accumulation in rice grain is important for food safety and human health.

Salmonella biofilms act as a continuous source for cross-contamination in the food processing environments. In this study, a stable rugose morphotype of Salmonella was first induced by sequential exposure to subinhibitory concentrations (SICs) of sodium hypochlorite (NaOCl) (ranging from 50 to 300 ppm over 18-day period) in tryptic soy broth.

Edwardsiella piscicida is a pathogenic bacterium responsible for significant losses in important wild and cultured fish species. E. piscicida strain MS-18-199 recovered from a diseased hybrid catfish from East Mississippi and showed resistance to florfenicol, chloramphenicol, oxytetracycline, doxycycline, erythromycin, tetracycline, azitromycin, spectinomycin, sulfonamide, and bacitracin. To explore the mechanisms of resistance in E.

An earlier report described a human case of necrotizing fasciitis (NF) caused by mixed infection with 4 Aeromonas hydrophila strains (NF1–NF4). While the NF2, NF3, and NF4 strains were clonal and possessed exotoxin A (ExoA), the NF1 strain was determined to be phylogenetically distinct, harboring a unique type 6 secretion...

The study applied a targeted metabolomics approach that uses a direct injection and tandem mass spectrometry (DI–MS/MS) coupled with a liquid chromatography–tandem mass spectrometry (LC–MS/MS)-based metabolomics of plasma to evaluate the effects of supplementing clay with or without Saccharomyces cerevisiae fermentation product (SCFP) on the metabolic status of dairy cows challenged with aflatoxin B1.

Background

Antimicrobial resistance (AMR) is a serious public health problem and a global concern. The inappropriate use of antibiotics has been identified by the World Health Organization as a major risk factor for AMR.

This report presents the first ultra‐high performance supercritical fluid chromatography diode array detector based assay for simultaneous determination of iridoid glucosides, flavonoid glucuronides, and phenylpropanoid glycosides in Verbena officinalis (Verbenaceae) extracts. Separation of the key metabolites was achieved in less than 7 min on an Acquity UPC2 Torus Diol column using a mobile phase gradient comprising subcritical carbon dioxide and methanol with 0.15% phosphoric acid.

Using longitudinal survey data from northern Ethiopia collected over 18 months, this study shows that conclusions about household food security are highly sensitive to measurement decisions. Especially important are 1) decisions about which food security indicators and cut-offs are chosen, and 2) whether analysis focuses on food security status at a given point in time or food security resilience over time.
