Acceptable daily intake or ADI is a measure of the amount of a specific substance (originally applied for a food additive, later also for a residue of a veterinary drug or pesticide) in food or drinking water that can be ingested (orally) daily over a lifetime without an appreciable health risk.

No animal species is known to be immune to the acute toxic effects of aflatoxins. Adult humans have a high tolerance for aflatoxin exposure and rarely succumb to acute aflatoxicosis, [31] but children are particularly affected, and their exposure can lead to stunted growth and delayed development, in addition to all the symptoms mentioned below ...
Several studies have been undertaken of the toxic effects of aflatoxin M 1 in laboratory animals. However, in comparison to aflatoxin B 1, relatively little is known about the toxicity of aflatoxin M 1, primarily because of the difficulty in obtaining sufficient quantities of the pure compound necessary for extensive toxicity testing. [8]
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]
Aflatoxin B 1, the most toxic, is a potent carcinogen and has been directly correlated to adverse health effects, such as liver cancer, in many animal species. [11] Aflatoxins are largely associated with commodities produced in the tropics and subtropics , such as cotton , peanuts , spices , pistachios , and maize .
The most common mycotoxin is aflatoxin. It can be very carcinogenic to both humans and animals. Aflatoxin is produced by two species of Aspergillus, A. flavus and A. parasiticus, which are known to affect plants including cereal grains, figs, nuts, and tobacco. [2] Cereal grains are one of the main ingredient in animal feed. The animals most at ...
Human foods: Vomitoxin is not a known carcinogen, unlike aflatoxin. Large amounts of grain with vomitoxin would have to be consumed to pose acute toxicity in humans. Currently, the chronic effects of low-dose exposure are unknown. The U.S. Food and Drug Administration has established a level of 1 ppm (parts per million) restriction of vomitoxin.
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.
