Red foxes (Vulpes vulpes) are the most prevalent wild carnivores in the world and definitive hosts of many pathogenic parasites for humans and farm animals. These animals travel great distances in search of prey and nests, and cause contamination of large geographic areas with parasites. For this reason, monitoring the parasitic pathogens of red foxes is particularly important in terms of public and animal health.

Assessing the potential ecological risks of chemical pollutants like heavy metals is a key tool of a sustainable environment.

PM2.5 samples were collected from residential, commercial, plaza and public green spaces in Lin’an, Hangzhou, in spring (March and April) and winter (February and December) in 2017. PAHs were detected by gas chromatography-mass spectrometry (GC-MS), and their sources were identified using the diagnostic ratio (DR) and principal component analysis-multiple linear regression (PCA-MLR). The average PAH concentration in winter was 1.3 times that in spring (p < 0.01).

Even though sediment Escherichia coli is a common source of contamination in freshwater environments, their characteristics such as virulence genes, biofilm forming capacity, antibiotic resistance, and level of reactive oxygen species (ROS) are not well understood. This study examined E. coli from freshwater sediments, sewage, and a collection of O157 isolates.

The objective of this study was to evaluate the efficacy of modified clinoptilolite (Minazel Plus®, MZ) as a mycotoxin adsorbent for preventing the negative the effects of ochratoxin A (OTA) on performance, pathohistological changes, and OTA residue in the eggs of laying hens.

Food-producing animals are an important reservoir and potential source of transmission of antimicrobial resistance (AMR) to humans. However, research on AMR in turkey farms is limited. This study aimed to identify risk factors for AMR in turkey farms in three European countries (Germany, France, and Spain). Between 2014 and 2016, faecal samples, antimicrobial usage (AMU), and biosecurity information were collected from 60 farms.

Methicillin-resistant Staphylococcus aureus infections are a global health problem. New control strategies, including fifth-generation cephalosporins such as ceftaroline, have been developed, however rare sporadic resistance has been reported. Our study aimed to determine whether disruption of two-component environmental signal systems detectably led to enhanced susceptibility to ceftaroline in S. aureus CA-MRSA strain MW2 at sub-MIC concentrations where cells normally continue to grow.

Journal of Food Safety, EarlyView. The present investigation was performed to determine the stability of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) under several industrial processing situations in dairies, including pasteurization, freezing, and storage in acidic conditions.

Prior research has suggested that the use of organic acids in the food industry may unintentionally enhance pathogenicity of Listeria monocytogenes strain N1-227 and R2-499. This study explored the connection between habituation to L-lactic acid or acetic acid and virulence in L. monocytogenes strains N1-227 and R2-499 using selected gene expression analysis and the in vivo Galleria mellonella wax worm model for infection.

To consistently disinfect fresh vegetables efficiently, the decay of disinfectants such as chlorine, electrolyzed oxidizing water (EOW), ozonated water, and plasma-activated water during the disinfection maintenance stage needs to be understood. The aim of our study was to evaluate the changes in the inactivation kinetics of slightly acidic electrolyzed water (SAEW) against human norovirus (HuNoV), based on the cabbage-to-SAEW ratio.

Background

Food safety issues were a growing concern in most countries; affecting the people’s health, social stability, economic development, and dairy product safety had always been an important topic of concern for consumers. This study is aimed at investigating the concerns of consumers about dairy product label information and its influencing factors. These survey data were reported for 4408 respondents with a total response rate of 96.35%.

Capsular polysaccharides (CPSs) protect bacteria from host and environmental factors. Many bacteria can express different CPSs and these CPSs are phase variable. For example, Bacteroides thetaiotaomicron (B. theta) is a prominent member of the human gut microbiome and expresses eight different capsular polysaccharides. Bacteria, including B.

Abstract

The development of detection method for aflatoxin gene cluster in Aspergillus flavus and Aspergillus parasiticusis is an effective approach to prevent the widespread of aflatoxins, which are considered as extremely, toxic substances. Herein, a hairpin DNA-assisted fluorescence probe switch based on Förster resonant energy transfer (FRET) was designed.

Reliable stable indicators are very important for assessing soil quality. This paper compares the dynamics of microbial parameters in two different soils (rich/poor in organic carbon), contaminated in laboratory experiments with an equal dose of heavy metals (HMs) after 30 and 90 days.

Soil enzyme activities are often used as indicators of soil contamination. The responses of the activities of specific soil enzymes, dehydrogenase, acid phosphatase, β-glucosidase, carboxylesterase, and urease to different land uses (soybean and rice crops, and a reference site) were analyzed. Changes in activity at the start and end of each crop cycle were quantified. In general, the catalytic activity of all enzymes was lower in both crops than in the reference site.

Concentrated pig production is a major source of environmental pollution. Metal–organic frameworks (MOFs) show potential for reducing heavy metal pollution. Two zirconium-based octahedral MOFs, UiO-66 and UiO-66-NH2, were prepared by solvothermal method and were characterized by XRD, SEM, FT-IR, and BET. The adsorption capacity, treatability, and reusability of the adsorbents were tested in batch experiments.
