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 ...
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.
In mice the elimination of FB 1 is very rapid, but in humans it could be much slower considering their body weight. [6] There are several possible pathways that cause toxic effects of fumonisin B 1. Most toxic effects are due to altered sphingolipid metabolism by inhibition of ceramide synthase. Production of reactive oxygen species could occur.

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.
