Thirty-three samples of wheat of the 1982 crop year from Kansas and Nebraska were analyzed for deoxynivalenol, T-2 toxin, zearalenone, and aflatoxin. Deoxynivalenol was identified in 31 of 33 samples, zearalenone was identified in 3 of 33 samples, and aflatoxin B1 was identified in 23 of 31 samples. One 1982 wheat sample from Illinois and one from Texas were also contaminated with deoxynivaleno...

BACKGROUND Aflatoxins are the most common mycotoxins that contaminate crops. They are produced by fungi such as Aspergillus flavus and Aspergillus parasiticus. Wheat (Tricitumaestivum) is one of the most important staple foods used in Iran, and the environmental conditions in the north of Iran are favorable to fungal growth. This study was designed in order to determine the aflatoxin concentrat...

Two experiments were carried out to determine the potential of oral yolk derived specific antibody against aflatoxin B1 in Japanese quails. In the first experiment egg yolk derived antibody against aflatoxin B1 was produced in layer quails. The potential of aflatoxin absorbent of the eggs from immunized and non-immunized layers was assayed in vitro. Egg yolk extracts derived from aflatoxin-BSA ...

Wild-type Aspergillus parasiticus produces, in addition to the colorless aflatoxins, a number of pigmented secondary metabolites. Examination of these pigments demonstrated that a major component was an anthraquinone, averufanin. Radiolabeling studies with [14C]averufanin showed that 23% of the label was incorporated into aflatoxin B1 by the wild type and that 31% of the label was incorporated ...

This study was conducted to assess major Aspergillus species and aflatoxins associated with groundnut seeds and cake in Eastern Ethiopia and evaluate growers' management practices. A total of 160 groundnut seed samples from farmers' stores and 50 groundnut cake samples from cafe and restaurants were collected. Fungal isolation was done from groundnut seed samples. Aspergillus flavus was the dom...

-Aflatoxin BI was given by ip injection to year-old female guinea-pigs and 6 hr later aflatoxin B1 and its metabolites were recovered and isolated chromatographically. Approximately 14~ of the administered toxin was represented by the isolated compounds. Aflatoxin B1 and M1 each accounted for approximately 3 7o, and the remaining 94~ was a product that migrated with the solvent front in a chlor...

A cohort of 18,244 mostly middle-aged (45-64 years) men residing in four small geographically defined areas of Shanghai was accrued between January 1986 and September 1989. In addition to an in-person interview regarding dietary and other past exposures, each subject donated a single void urine sample at recruitment so that the presence of aflatoxins in urine could be assessed. In addition, a 1...
