Aflatoxin transformation products are sometimes found in eggs, milk products, and meat when animals are fed contaminated grains. [ 2 ] [ 27 ] A study conducted in Kenya and Mali found that the predominant practices for drying and storage of maize were inadequate in minimizing exposure to aflatoxins.
Aflatoxin M 1 is the hydroxylated metabolite of aflatoxin B 1 and can be found in milk or milk products obtained from livestock that have ingested contaminated feed. The carcinogenic potency of aflatoxin M 1 in sensitive species is about one order of magnitude less than that of aflatoxin B 1 .
Aflatoxin B 1 is an aflatoxin produced by Aspergillus flavus and A. parasiticus. It is a very potent carcinogen with a TD 50 3.2 μg/kg/day in rats. [ 4 ] This carcinogenic potency varies across species with some, such as rats and monkeys, seemingly much more susceptible than others.
A. parasiticus produces aflatoxins B1, B2, G1, and G2, named for the colours emitted under UV light on thin-layer chromatography plates—either blue and green. The numbers refer to the type of compound with 1 being major and 2 being minor. [3] These aflatoxins are carcinogenic mycotoxins which have detrimental effects to humans and livestock. [4]
At least 28 dogs have died and another eight have become sick after eating dog food that contained high levels of a toxin called aflatoxin, the Food and Drug Administration said, as some pet foods ...
The discovery of aflatoxins led to substantial changes in agricultural practices and regulations on how grains and legumes were grown, harvested, and stored. [21] The amount of aflatoxins produced by A. flavus is affected by environmental factors. If other competitive fungal organisms are present on host plants, aflatoxin production is low.
Molds are a natural part of the environment and found almost everywhere moisture and oxygen are present, ... The most dangerous type are aflatoxins, which can be carcinogenic to humans, ...
Aspergillus parvisclerotigenus is a species of fungus in the genus Aspergillus.It is from the Flavi section. [2] The species was first described in 2005. [1] A. parvisclerotigenus has been isolated in Nigeria and has been found to produce aflatoxin B1, aflatoxin B2, aflatoxin G1, aflatoxin G2, aflatrem, aflavarin, aspirochlorin, cyclopiazonic acid, kojic acid, and paspaline.
