|Abstract||One of the research activities carried out by the Quality of Agricultural Products Department of the CRA-W concerns the safety and quality of animal feed. The Department is one of the reference European laboratories for the detection and quantification of meat and bone meal (MBM) contamination in animal feed. Research in this area started at CRA-W in 1997 by developing new analytical approaches based on Near Infrared spectroscopy. NIR spectroscopy offers the advantage of being rapid, accurate and independent of human analyst skills needed in the optical microscopy method (official method for MBM detection). The combination of NIRS and a microscope allows high quality spectra for small (50 ? 1000 µm) feed particles. NIRM method has been proposed as an alternative to the official method; the optical microscopy. Studies undertaken in the framework of the activities of different projects as Farimal, Feed Safety, Safeed-Pap or of the Community reference laboratory for Animal Proteins (CRL-AP) have demonstrated the high potential of the NIRM method combined with chemometrics to detect animal particles in feedingstuff at concentrations as low as 0.5 %. The method is efficient for the specific detection of animal particles, and for the discrimination between fish, pig, cattle and poultry meal. Chemometric models like Partial Least Squares (PLS) and Support Vector Machines (SVM) as well as some wavelength-based rules have been developed in order to determine the origin of the animal particles. Some works have been done in order to combine the NIRM method with other analytical methods like optical microscopy or Real Time Polymerase Chain Reaction (PCR). These methods can give a confirmation on the presence of animal species origin of the particles. The method is running under accreditation ISO 17025 since 2005 at the CRA-W.|
