Cereal and cereal by-products, corn grains and corn silage are thought to be the most exposed ingredients to mould and mycotoxin contamination. This article by Francisco Martinex and Fernando Aguado at Nufoer SL in Spain looks at the major mycotoxins and why it is important to test for an array and not for a single one in order to analyse feed quality and risks

Mycotoxicosis refers to the different diseases caused by exposure to different mycotoxins, and it has a high occurrence in livestock production. Mycotoxins are fungal secondary metabolites, toxic to humans and animals, produced by certain species of fungus.

The growth capacity of these fungi depends on several environmental factors such as moisture, temperature and availability of energy and nitrogen sources. Likewise, the production of mycotoxins depends on specific environmental factors, and the presence of mycotoxigenic fungi does not imply a presence of mycotoxins and vice versa, since mycotoxins present great stability and can be present in feedstuffs even after the deterioration of the producing fungus.

Cereal and cereal by-products, corn grains and corn silage are thought to be the most exposed ingredients to mould and mycotoxin contamination, depending on various factors such as grain handling, processing and storage conditions.
