The analytical difficulties in mycotoxin determination have given rise to the development of mycotoxin reference materials by the European Community Bureau of Reference (BCR) in cooperation with several European Laboratories, among them the National Institute of Public Health and Environmental Protection. The first project undertaken concerned four milk powders certified for their aflatoxin M1 content (concentrations 0,0.1, 0.3 and 0.8 mug/kg). Projects that are well-advanced include two peanut meals (aflatoxin B1 contents 0 and ca. 200 mug/kg) and two compounded animals feedingstuffs (aflatoxin B1 contents 0 and 10 mug/kg). Mycotoxin reference materials are also under development for zearalenone in wheat and maize, and for ochratoxin A in wheat. The general approach followed in the development and certification of mycotoxin reference materials (preparation, testing for homogeneity and stability, intercomparisons of methods and certification exercise) will be discussed and exemplified with the help of the completed project on aflatoxin M1 in milk powder
