Rapid methods for feed safety: the CONffIDENCE project
Rapid Methods Conference & Open Day
25- 27 January 2010

CONffIDENCE in a nutshell
CONtaminants in food and feed:
Inexpensive DEtectioN
for Control of Exposure
CONffIDENCE, a European approach
CONffIDENCE passport
FP7 Collaborative Project first call “Food, Agriculture & Fisheries, and Biotechnology”
Duration: May 2008 – April 2012 16 partners from 10 countries, representing
universities, research institutes, industry and SMEs
Budget: 7.5 Mio € Co-ordinator: RIKILT - Institute of Food
Safety, part of Wageningen UR (NL)
Why CONffIDENCE ?
To assure chemical safety and quality in the European food supply; support of EC policies and competitiveness of food and feed industries
Why CONffIDENCE ?
To improve multi-detection (“multiplex”) possibilities, e.g. for antibiotics
Why CONffIDENCE ?
To improve inexpensive screening possibilities, e.g. for metal speciation

Why CONffIDENCE ?
To speed-up analysis for
factory approval of lots
Why CONffIDENCE ?
To contribute to the assessment of risks of emerging contaminants e.g. plant toxins such as pyrrolizidine alkaloids
Why CONffIDENCE ?
To contribute to the generation of data for exposure assessment, e.g. for PFC’s:
Perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA) and their saltsScientific Opinion of the Panel on Contaminants in the Food chainAdopted on 21 February 2008
“Due to the substantial lack of suitable analytical data, many assumptions have been made in order to derive exposure estimates.”
The objectives
Development and validation of new simplified inexpensive detection methods for chemical contaminants from farm to fork
The objectives
Improved exposure assessment through monitoring of selected contaminants
The objectives
Contribute to validation of predictive hazard behaviour models
The objectives
Dissemination and training of new detection methods to all relevant stakeholders, to advance technology exploitation
Food & Feed Fish/shellfish Fish feed Cereals Cereal-based feed
Potatoes/vegetables Honey Eggs Meat Dairy products
The commoditiesBased on their relevance for consumer safety and trade, the following target commodities were selected:
The target contaminants
Persistent Organic Pollutants (POPs): - dioxin-like PCBs- brominated flame retardants- polycyclic aromatic hydrocarbons (PAH)
The targeted analytes represent a balance of emerging contaminants, high frequency detected residues as well as compounds which are not satisfactorily covered by current analytical methods.
The target contaminants
Persistent Organic Pollutants (POPs) Perfluorinated compounds (PFCs):
- PFOS- PFOA
The targeted analytes represent a balance of emerging contaminants, high frequency detected residues as well as compounds which are not satisfactorily covered by current analytical methods.
The target contaminants
Persistent Organic Pollutants (POPs) Perfluorinated compounds (PFCs) Pesticides:
- paraquat- diquat- dithiocarbamates
The targeted analytes represent a balance of emerging contaminants, high frequency detected residues as well as compounds which are not satisfactorily covered by current analytical methods.
The target contaminants
Persistent Organic Pollutants (POPs) Perfluorinated compounds (PFCs) Pesticides Veterinary drugs:
- antibiotics, e.g. tetracyclines- coccidiostats, e.g. ionophores
The targeted analytes represent a balance of emerging contaminants, high frequency detected residues as well as compounds which are not satisfactorily covered by current analytical methods.
The target contaminants
Persistent Organic Pollutants (POPs) Perfluorinated compounds (PFCs) Pesticides Veterinary drugs Heavy metals speciation:
- inorganic arsenic- methyl mercury
The targeted analytes represent a balance of emerging contaminants, high frequency detected residues as well as compounds which are not satisfactorily covered by current analytical methods.
