Title Preliminary study of mycoflora and mycotoxins in grain dust from New Orleans area grain elevators
Bibliographic information July 1983, Vol.44, No.7, p.485-488. 18 ref.
Abstract Known mycoflora of commercial grain includes species of Penicillium, Aspergillus, and Fusarium - fungi that may produce ochratoxins, aflatoxins and zearalenone. Thin layer chromatography was used to analyse methylene chloride and water extracts of dust samples collected from several locations and dust control systems. Analytical detection limits were 50ng zearalenone/g of dust, 10ng/g for ochratoxin and 5ng/g for aflatoxins. None of the 15 samples analysed contained any detectable amount of aflatoxins or ochratoxin A, but 10 of the 15 samples contained zearalenone at levels from 25 to 100ng/g.
