Abstract The EU Rapid Alert System for Food and Feed (RASFF) shows that controls on chemical contaminants in food and feed are essential for food safety in Europe . Safer food, through rapid and cost-efficient tests for detecting chemical contaminants in food and animal feed, is the major goal of a new four-year European Commission funded research project. This project, launched in May 2008, is entitled ?CONffIDENCE, Contaminants in Food and Feed: Inexpensive Detection for Control of Exposure?. The project is coordinated by RIKILT and the consortium consists of 17 partners from 10 European countries. The CONffIDENCE project has been designed to provide validated screening tools, which are simple, inexpensive and rapid and are able to detect as many chemical contaminants in parallel as possible. These include persistent organic pollutants (POPs), perfluorinated compounds (PFCs), pesticides, veterinary pharmaceuticals (coccidiostats and antibiotics), heavy metals and biotoxins such as alkaloids, marine toxins and mycotoxins. Rapid tests are developed and validated for meat, eggs, fish and fish feed, cereal-based food/feed and vegetables. Various new methods based on multiplex technologies are developed. After validation the new methods will be applied in demonstration activities which will help to gauge contaminant exposure and validate the risk assessment models. For more information, visit http://www.conffidence.eu . Amongst the methods developed in the framework of this project, one of them is based on the near infrared hyperspectral imaging for detection of ergot ( Claviceps purpurea ) in cereals. Ergot was selected because of its increasing presence in recent years in cereals and food products. To reduce the risk of poisoning, the European directive 2002/32/EC on undesirable substances in animal feed, fixed a limit in the EU of 0.1% for ergot in all feedingstuffs containing unground cereals. For this study, a total of 85 ergot bodies issue from different sources (Belgium, The Netherlands , Germany and Denmark) and 100 wheat and barley kernels issue from several varieties and locations in Belgium have been collected and analyzed with a MatrixNIR TM Chemical Imaging System (Malvern instruments Ltd). This instrument is active in the 900-1700 nm range and the configuration used allows to collect the NIR spectra of 10 kernels in 5 minutes. A total of around 3000 spectra from each kernel is obtained. This research showed the potential of NIR hyperspectral imaging to discriminate the ergot bodies from barley and wheat kernels. Additional developments will be undertaken for the quantification of ergot bodies in the samples. Further research will be also carried out in order to develop and validate a method allowing the on-line detection of ergot bodies in cereals.
