Nanotechnology is poised to have a huge impact on food packaging applications. Bimetallic and trimetallic nanoparticles (NPs) are formed by combining two and three different metals and metal oxides, respectively.

Scarce studies have investigated the impact of fumonisin B1 (FB1) on the hepatic tissue fatty acid (FA) profile, and no study is available on piglets. A 10-day in vivo experiment was performed on seven piglets/group: control and FB1-fed animals (diet was contaminated with fungal culture: 20 mg FB1/kg diet). Independent sample t-test was carried out at p < 0.05 as the significance level. Neither growth, nor feed efficiency, was affected.

The impact of zearalenone (ZEN) on female reproduction remains an issue, since its effects may differ among exposed cell types. Besides the use of decontaminants in animal diet, other approaches should be considered to minimise ZEN effects after exposure. Since the first organ in contact with ZEN is the gastrointestinal tract, we hypothesise that products of microbiota metabolism may play a role in ZEN detoxification.

The aim of this study was to investigate the prevalence and distribution of Campylobacter species in a variety of fresh and frozen meat and offal products collected from retail outlets in New South Wales (NSW), Queensland (Qld), and Victoria (Vic). A total of 1,490 chicken, beef, lamb, and pork samples were collected from Australian supermarkets and butcher shops over a 2-year sampling period (October 2016 to October 2018). Campylobacter spp.

ABSTRACT Organophosphate esters used as flame retardants and plasticizers are ubiquitous contaminants in surface waters. Many studies indicate that these compounds are neurotoxicants, endocrine disruptors and may affect reproduction and development of aquatic organisms. Thus, analytical methods that allow accurate quantification of these contaminants at environmentally relevant concentrations are desirable for risk assessment studies.

During the summer of 2015, polycyclic aromatic hydrocarbons (PAHs) in the atmosphere were collected by passive air samplers in typical urban–rural fringe of Wuhan–Ezhou region, Central China. The results showed that 16 kinds of PAHs were ubiquitous with the concentrations of ∑16PAHs from 14.69 to 136.30 ng·m−3 and the mean concentration of 43.03 ng·m−3. Phenanthrene (Phe), fluoranthene (Fla) and pyrene (Pyr) were major components, which accounted for 81% of ∑16PAHs.

In this study, a simple and reliable sample preparation method based on an efficient version of homogeneous liquid-liquid extraction combined with dispersive liquid-liquid microextraction solidification of floating organic drop has been introduced to analyze some pesticide residues in fruit and fruit juice samples with gas chromatography-flame ionization detection.

A biochip chemiluminescent immunoassay was validated for multi-mycotoxins screening in maize. Screened mycotoxins were aflatoxins B1 (AFB1) and G1 (AFG1) ochratoxin A (OTA), zearalenone (ZEA), toxin T2 (T2), fumonisins (sum of FB1 and FB2) and deoxynivalenol (DON). The method included a single extraction step with acetonitrile:methanol:water (50:40:10, v/v/v).

Many pesticides are used for pest control during oat production and storage, making necessary to employ multiclass methods for pesticide residue determination. In this work, an efficient QuEChERS method was established for multiresidue determination of 60 pesticides in oats by liquid chromatography with tandem mass spectrometry (LC-MS/MS).

Apolipoprotein A-I is an anti-inflammatory, antioxidative, cardioprotective, anti-tumorigenic, and anti-diabetic in mammals. Apolipoprotein A-I also regulates innate immune defense mechanisms in vertebrates and invertebrates. Apolipoproteins A-I from mammals and several teleosts display antibacterial activities against Gram negative and Gram positive bacteria.
