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 ...
The other primary mycotoxin groups found in mushrooms include: orellanine, monomethylhydrazine, disulfiram-like, hallucinogenic indoles, muscarinic, isoxazole, and gastrointestinal (GI)-specific irritants. [28] The bulk of this article is about mycotoxins that are found in microfungi other than poisons from mushrooms or macroscopic fungi. [21]
When compared to other trichothecene mycotoxins which can form in grains and forages, vomitoxin is relatively mild. Reduced feed intake, with its accompanying decrease in performance, is the only symptom of vomitoxin toxicity livestock producers will likely encounter. This response to vomitoxin appears to occur through the central nervous system.
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. [28]
They are produced on many different grains such as wheat, oats, or maize by various Fusarium species including F. graminearum, F. sporotrichioides, F. poae, and F. equiseti. Some moulds that produce trichothecene mycotoxins, such as Stachybotrys chartarum, can grow in damp indoor environments.
Citrinin is a mycotoxin which is often found in food. It is a secondary metabolite produced by fungi that contaminates long-stored food and it can cause a variety of toxic effects, including kidney, liver and cell damage. Citrinin is mainly found in stored grains, but sometimes also in fruits and other plant products.
Mycotoxicology is the branch of mycology that focuses on analyzing and studying the toxins produced by fungi, known as mycotoxins. [1] In the food industry it is important to adopt measures that keep mycotoxin levels as low as practicable, especially those that are heat-stable.
In grains and legumes, postharvest disease results in the production of mycotoxins. [3] The largest economic loss caused by this pathogen is a result of aflatoxin production. In the United States, annual economic loss estimations of peanuts, corn, cottonseed, walnuts, and almonds are less severe when compared to Asia and Africa. [4]
