New analytical methodology for determining aflatoxin M1 in milk has been validated using the European Community Bureau of Reference (BCR) aflatoxin M1 in powdered milk certified reference material (CRM). Good agreement with the certified values for aflatoxin M1 were obtained using an immunoaffinity column clean-up procedure for the preparation of milk samples. This demonstrated the validity of this novel approach. Similarly, using the CRM's a fully automated sample handling procedure utilising robotics was validated for making routine aflatoxin determinations. The use of CRM's has now become part of the normal quality assurance procedure for survey work for aflatoxin M1 in milk, and CRM's are analysed 'blind' for every 15 survey samples. The need for additional mycotoxin CRM's in foods and animal feeds is discussed in relation to existing European Regulations, and the needs for intercomparison of surveillance data. Preliminary work under the BCR programme is outlined concerning the preparation of a 4-deoxynivalenol calibrant solution, and the certification of cereals containing this Fusarium mycotoxin
