title: Evaluation of measurement uncertainties of an analytical method for the determination of aflatoxin M1 in milk and milk powder.
abstract: The mycotoxin aflatoxin M1 (AfM1) is a serious food safety hazard for which the European Commission has already established a maximum permissible level of 0.05 μg/kg AfM1 in milk and products thereof. For control analysis laboratories are increasingly asked to submit full uncertainties of their analytical results.The evaluation of measurement uncertainties of an analytical method for the determination of AfM1 in milk and milk powder on the basis of 'in-house' validation data in compliance with the 'Guide to the Expression of Uncertainty in Measurement (GUM)' [1] and the 'EURACHEM Guide' [2] is described. A similar approach will be used to assess the performance of methods employed by laboratories participating in the certification of reference materials for AfM1 in milk powder.
