Abstract
The cellulose chromatography method of the Association of Official Analytical Chemists for determination of aflatoxin M1 [produced by Aspergillus flavus and related organisms] was compared with a 2 dimensional TLC procedure. The minimum detectable aflatoxin M1 by the Official procedure was approximately .01 .mu.g/kg while the TLC procedure has a claimed sensitivity of .004 .mu.g/kg. Analyses of milk samples by TLC agreed with results of the Official procedure in the range of .01-.25 .mu.g/l. Each method consistently yielded recoveries greater than 87%, and there was no significant difference between means or variances of each method. The TLC method took less time than the Official method and showed a reproducible lower threshold sensitivity of .005 .mu.g/l.
