Contaminants in food and feed

CONffIDENCE project deliverables

The project will deliver both scientific-technical solutions for the monitoring and enforcement of food safety as well as information and training of the developed methods.This will include:

  • Simple, fast, inexpensive multiplex screening assays (multi-analyte multi-class detection) that are fully validated for use by industry and enforcement laboratories. The scope of these technologies is described in more detail below.
  • Impact demonstration. The developed technologies will be applied to a variety of samples thus allowing exposure assessments and creation of occurrence data bases.
  • Dissemination of the results amongst key the stakeholders: scientific community, end-users and consumers
  • Training workshops for governmental, agricultural and industrial end-users
  • Education and training modules for students

The technologies

A selection of the most recent and advanced technologies will be applied:

• Multiplex flow cytometry

• Multiplex Surface Plasmon Resonance (SPR) biosensor

• Multi-component dipstick assays

• Magneto-immunosensor

• Near Infrared (NIR) imaging methods

• Cytosensor

• Simplified mass spectrometric (MS) methods

• Automated contaminant profiling in MS data

The target contaminants and residues

The targeted analytes represent a balance of (i) emerging contaminants, (ii) chemical residues that are detected at high frequency and (iii) compounds which are not satisfactorily covered by current analytical methods:

  • Persistent Organic Pollutants (POPs):
    – dioxin-like PCBs (+ metabolites, e.g. PCB-OH)
    – brominated flame retardants
    – polycyclic aromatic hydrocarbons (PAHs)
  • Perfluorinated compounds (PFCs):
    – e.g. PFOS, PFOA
  • Pesticides:
    – paraquat/diquat
    – dithiocabamates
  • Veterinary drugs:
    – coccidiostats (lasalocid, monensin, salinomycin, narasin, nicarbazin)
    – antibiotics (tetracyclines, sulfonamides, chloramphenicol, tylosin)
    – malachite green
  • Heavy metals:
    – inorganic arsenic species
    – methyl-mercury
  • Biotoxins:
    – alkaloids (pyrrolizidine, tropane, ergot)
    – marine biotoxins (PSP/DSP)
    – mycotoxins (DON, ZEA, T-2/HT-2, fumonisins FB1, FB2)

  • Fish/shellfish
  • Fish feed
  • Cereals
  • Cereal-based feed
  • Potatoes
  • Vegetables
