An LC-MS/MS method was developed and validated for the detection and quantification of 23 mycotoxins in different varieties of sorghum. The method performance characteristics were as follows: suitable linearity ranges for all 23 mycotoxins with p-value >0.05; limits of detection (1.2-50 mu g/kg), limits of quantification (2.5-100 mu g/kg), repeatability (RSDr, 7-22%), intermediate precision (RSDR, 14-44%) and apparent recovery (0.2-11%, expressed as bias). The method was applied to analyze 10 samples obtained from retail shops in Belgium (n = 8) and Germany (n = 2). Nine of the 10 samples (90%) were positive for the following mycotoxins: aflatoxin B-1 (50 mu g/kg), alternariol monomethyl ether (
