title: Mycotoxins in animal feedstuffs: sensitive thin layer chromatographic detection of aflatoxin, ochratoxin A, sterigmatocystin, zearalenone, and T-2 toxin.
abstract: Improvements have been made to a previously described multi-mycotoxin method that involved a membrane cleanup step. Using 2-dimensional thin layer chromatography and appropriate solvent systems, aflatoxin B1 can be detected in mixed feedstuffs and various ingredients at levels ranging from 0.1 to 0.3 microgram/kg. Corresponding detection limits for ochratoxin A and sterigmatocystin are 5 to 20 microgram/kg and for T-2 toxin and zearalenone 20 to 200 microgram/kg.
