Abstract	Mycotoxms are compounds that might be produced when certam fungi grow in seeds and grains. Several Fusarium, toxins (zearalenone, fumomsms and deoxyni valenol, short for ZEA, FUMO and DON), Aspergillus toxins (aflatoxins and ochratoxm A, short for AFA and OA) and Penicdlium toxms (ochratoxm A) are of great concern for human and ammal health. Twenty samples of clean and dry corn, 20 of gnts and 20 of corn meal were analyzed with an enzymelmked immunosorbent assay (ELISA), 7 out of the 20 corn samples and the 20 corn meal were analyzed with thm-layer chromatography (TLC) for companson With the test kit The samples were collected from a processmg plant m southern Brazil according to the production schedule during four months. The mycotoxins analyzed by the test kit were aflatoxms, zearalenone, fumomsms, deoxymvalenol and ochratoxm A. Most of the samples of corn, gnts and corn meal were positive for one or more toxms when tested with this procedure The mycotoxins analyzed by the TLC were aflatoxms, ochratoxin A and zearalenone Companng the results of the two methods, the ELISA showed easier to handle, faster, but gave higher concentration levels than the TLC and some false positive results Despite of bemg a very common procedure, the TLC IS time consummg, needs tramed personnel and good laboratory facihues Thus, ELISA kits are useful tools m the held, gram elevators and m the mdustry for mycotoxm screening and momtonng purposes.
