  • Title: International mycotoxin check sample program: Part II. Report on laboratory performance for determination of aflatoxin M1 in milk.
    Author: Friesen MD, Garren L.
    Journal: J Assoc Off Anal Chem; 1982 Jul; 65(4):864-8. PubMed ID: 6811545.
    Abstract:
    A sample of aflatoxin M1-contaminated lyophilized cow's milk was analyzed by 80 laboratories in 30 countries. Sufficient data were obtained to permit a statistical comparison of the performance of laboratories using AOAC methods I and II and those using high performance liquid chromatography for quantitation. A significant difference was noted between means for laboratories using AOAC method I as opposed to those using HPLC methods. Overall reproducibility (between- plus within-laboratory precision) was best for laboratories using HPLC methods and poorest for those using AOAC method II.
