New Rapid Test Developed for Toxic Ergot Alkaloids in Cereal Grains

Grain processors regularly face the presence of toxic ergot alkaloids (EAs). Europe has new limits since early 2022, but analysis is expensive and time[1]consuming. The industry therefore needs a faster, cheaper method. Infected batches are then recognised earlier. Thanks to a successful TKI project, led by Wageningen Food Safety Research, this method is on its way.

Biochip Array Technology: Maximising the Screening Capacity of Veterinary Drug Residues in Food

The use of veterinary drug residues in food producing animals is globally restricted and an important topic in food safety. The emergence of problems such as antibiotic resistance has led to growing concerns for public health. high levels of food imports have increased the need for reliable, efficient and user-friendly screening methods.

Biochip array technology allows the simultaneous screening of multiple veterinary drug residues from a single sample. This consolidates testing and reduces the quantity of samples to be assessed by confirmatory analysis. This study reports the applicability of biochip arrays to the multiplex screening of antimicrobials , anthelmintic drugs and growth promoters in food.

Pesticides Testing

Applicability of Biochip-based immunoassays to the detection of pesticides

Pesticides are broadly applied to kill pests and their application to agricultural crops have a negative impact on bees, which can contribute to the loss of bee colonies. The widespread release of pesticides into the environment can also contribute to the occurrence of pesticides
in the food supply. Pesticides are regulated globally by various governmental agencies. The availability of screening methods allowing the detection of pesticides is then beneficial in test settings to monitor their presence to ensure food safety.

This study reports the applicability of biochip-based immunoassays to the detection of acetamiprid/thiacloprid, azoxystrobin, carbaryl, clothianidin, coumaphos, fenpyroximate, imidacloprid and thiamethoxam.

The Use of Biochip Array Technology for Rapid Multimycotoxin Screening

Biochip array kit and analyzer.—Simultaneous semiquantitative screening of mycotoxins in feed was carried out using the Myco 7 biochip array kit (EV4065; Randox Food Diagnostics, Crumlin, United Kingdom).

The kit contains multianalyte biochips, assay diluent, conjugate diluent, multianalyte conjugate, a set of multianalyte calibrators (spanning the range of each assay), multianalyte controls, signal reagent, washing buffer, calibration disc, and barcodes.

The biochips were supplied in carriers (3 × 3 biochips per carrier), and a carrier handling tray was provided with the system that allows the simultaneous handling of six carriers (54 biochips). Data were generated and processed with the semiautomated benchtop biochip analyzer Evidence Investigator (EV3602; Randox Food Diagnostics, Crumlin, United Kingdom).

HMF Testing

Application of an easy to use assay kit on the RX misano analyser for the reliable determination of HMF in honey

Hydroxymethylfurfural (HMF) is produced by acid-catalyzed dehydration of sugars, primarily fructose. HMF occurs naturally over time in most honeys but elevated concentrations provide an indication of overheating, poor storage conditions, possible adulteration with other sugars or syrups and/or higher age of the honey.

The levels of HMF in honey are regulated in many countries, therefore reliable analytical tools for the determination of HMF are relevant to monitor the conformity of honey to regulatory standards. This study reports the application of an easy to use assay kit applied to the RX misano analyser for the reliable determination of HMF in honey.

Simple measurement of D-Glucose, D-Fructose and sucrose in honey with two assay kits applied to the RX misano analyser

Honey is a natural product composed mainly of sugars, water and also a wide range of other minor constituents such as phenolic compounds. Fructose and glucose are the main sugars present in honey, the remainder includes disaccharides (e.g. sucrose) and higher oligosaccharides. Sugar content of honey has been considered a measure of the purity and important in quality control of honey.

The development of analytical methods which monitor the compliance to quality specific cation, facilitates fraud prevention and the protection of authentic honeys. This study reports the analytical performance of two assay kits, one for the determination of D-glucose and D-fructose and the other for the determination of sucrose in honey samples, involving simple sample preparation.

Sensitive simultaneous screening of Nitroimidazoles and chloramphenicol on a Biochip Array through the use of dedicated multi-analyte immunoaffinity columns for honey sample clean-up

Nitroimidazoles (NMZ) and Chloramphenicol (CAP) are prohibited from use in foodstuffs of animal origin in the EU (Annex IV of EU Commission Regulation 37/2010). The availability of ever more sensitive screening methods is then crucial for the efficient monitoring of honeys. For this reason, the current Antimicrobial Array V (AM V) biochip assay has been adapted to include the use of dedicated Immunoaffinity Columns (IACs) for the enhanced, simultaneous clean-up of NMZs and CAP from honey samples for the ultra-sensitive multiplex detection of Metronidazole (MNZ), Dimetridazole (DMZ), Ronidazole (RNZ) and CAP. Moreover, these multi-analyte affinity columns keep within the same timeframe as the current solvent extraction method.

Validation of a Biochip Chemiluminescent Immunoassay for Multi-Mycotoxins Screening in Maize (Zea mays L.)

The word mycotoxin comes from the conjugation of the word “mykes”, which in Greek means fungus and from the work “toxicum”, which in Latin stands for poison. Mycotoxins are secondary metabolites of relatively small molecular weight (MWaround 700) which can pre- or post-harvest contaminate a wide range of commodities from animal or plant origins(Chauhan et al. 2016).
