Aflatoxin and chromosomal studies [PDF]
Bulletin of Environmental Contamination and Toxicology, 1966 Aspergillus flavus is known to be a common fungal contaminant on groundnuts, groundnut cake, and meal, Four metabolites have been designated as comprising the toxins produced by the fungus. Collectively, the B1, B2, G1, and G2 toxic factors have come to be called aflatoxin; the B1 form being considered the most common naturally occurring form.

Incidence of aflatoxins and aflatoxin producing fungi in animal feedstuffs
Mycopathologia, 1979Fifty four samples including 5 of broken rice, 8 of corn grains, 8 of corn gluten feed, 13 of cottonseed cake and 4 each of rice polish, corn gluten, sesame oil cake, guar meal and wheat bran were screened for the presence of aflatoxins. Among all the samples, 14 were damaged and 40 apparently undamaged.

Influences of climate on aflatoxin producing fungi and aflatoxin contamination
International Journal of Food Microbiology, 2007Aflatoxins are potent mycotoxins that cause developmental and immune system suppression, cancer, and death. As a result of regulations intended to reduce human exposure, crop contamination with aflatoxins causes significant economic loss for producers, marketers, and processors of diverse susceptible crops.

Ecology of aflatoxin producing fungi and biocontrol of aflatoxin contamination
Mycotoxin Research, 2006Aflatoxins, highly toxic and carcinogenic compounds that frequently contaminate foods and feeds, are produced by several genera in the genusAspergillus. Aspergillus flavus, the most common species causing crop contamination, is a common inhabitant of the Sonoran desert of North America where it resides in complex communities composed of diverse ...

Biotransformation of Aflatoxin
Food Biotechnology, 1989Abstract Food grade fungi were screened for their capacity to degrade aflatoxin B1 (AFB1) in order to develop a biological detoxification process for contaminated feeds. An agar technique based on defluorescence of AFB1 was used for this purpose.

Aflatoxins and Sterigmatocystins
1974In this review the term mycotoxicosis refers to poisoning of man or animals by ingestion of foodstuffs contaminated with certain moulds and/or with their metabolic products (mycotoxins).

The biosynthesis of the aflatoxins
Journal of the Chemical Society D: Chemical Communications, 1970A new metabolite of Aspergillus versicolor, demethylsterigmatocystin (II) has been converted into 5-hydroxydihydrosterigmatocystin (IV) specifically labelled with 14C in the O-methyl group—this compound is shown to be a biogenetic precursor of aflatoxins B2 and G2, (IX) and (XI), respectively, in A. parasiticus: a second new metabolite of A. versicolor

Aflatoxins in cosmetics containing substrates for aflatoxin-producing fungi
Food and Chemical Toxicology, 199229 random samples of eight different products of skin cleansing creams or powders and skin peeling products (including practically all products of this type available on the German market), containing substrates for aflatoxin-producing fungi or plant parts directly connected with such substrates, such as almond bran, peach bran, apricot seeds, wheat ...

That fungi can produce toxic substances has been recognised for centuries. The well-known hazards of the mushrooms, although not strictly relevant to this meeting, are of considerable interest and have been reviewed by Wieland and Wieland.1 The toxins induce a pathological change in many of the major organs.
