title: Natural occurrence of zearalenone and toxicogenic fungi in amaranth grain.
abstract: Zearalenone was detected as the natural contaminant in two samples of Amaranthus cruentus grains (1980 micrograms/kg and 420 micrograms/kg, respectively). Fungi isolated from these samples were screened for mycotoxin production. Two of eight isolates of Fusarium (F. equiseti and F. moniliforme) produced zearalenone. One of four isolates of Aspergillus flavus and all four isolates of A. parasiticus produced aflatoxins. Other species potentially toxicogenic such as Aspergillus versicolor, Penicillium viridicatum, P. puberulum, P. crustosum, P. citrinum, P. expansum and Fusarium solani were also found.
