Aflatoxin contamination of preharvest maize intermittently presents serious problems in grain storage and in animal health. To determine whether this mycotoxin can be translocated through the ear in the absence of hyphae, we harvested 21 grains from

Low incidence and levels of aflatoxin were identified in corn of all grades grown in the Midwest in 1964, 1965, and 1967. Later surveys indicate that corn grown in southern regions is subject to invasion byAspergillus flavus and subsequent aflatoxin

This research examines the distribution of aflatoxins among conidia and sclerotia of toxigenic strains of Aspergillus flavus Link and Aspergillus parasiticus Speare cultured on Czapek agar (21 days, 28 °C). Total aflatoxin levels in conidia and scle

A method was developed to determine deoxynivalenol and zearalenone in corn, wheat, oats, rice and barley. The toxins are extracted with methanol/water (50:50, v/v) (2×) and partially purified by partitioning into ethyl acetate and then defatting wit
