Treatment of human liver cells with aflatoxin B 1 at doses that ranged from 3–5 μmol/L resulted in the formation of aflatoxin B 1-DNA adducts, 8-hydroxyguanine lesions and DNA damage. [41] Carcinogenicity The carcinogenicity of aflatoxin B 1, which is characterized by the development of liver cell carcinoma, has been reported in rat studies ...
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.

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.
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 ...
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 lethal dose for 50% of dogs is 100 – 200 mg per kilogram (kg) of body weight, yet some dogs will exhibit signs of toxicosis after ingesting as little as 20 mg per kg. [38] In case of accidental intake of chocolate, especially involving a smaller dog, contact a veterinarian or animal poison control immediately; it is commonly recommended ...
Sterigmatocystin is a polyketide mycotoxin produced by certain species of Aspergillus.The toxin is naturally found in some cheeses.. Sterigmatocystin is a toxic metabolite structurally closely related to the aflatoxins as it is the penultimate precursor of aflatoxins B1 and G1. [1]
