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.
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, 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.
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.
Autumn Nelson said she was seeking help for alcohol addiction last spring when fellow members of the Blackfeet Nation in Montana suggested a rehabilitation center in Phoenix, far to the south.

The call center employed 50-70 people to lead an “aggressive” telemarketing campaign, court records show. Florida call center manager bamboozled doctors in $67 million Medicare scam, jury says ...
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.
