Mycotoxins are toxic secondary molecules produced by moulds. These molecules can cause a wide range of effects depending on the molecular family, combination of contaminants and rearing environment. They occur differently in each part of the world, according to climate and agricultural practices.
Aflatoxins, Ochratoxins, Fumonisins, Zearalenones and Trichothecenes (DON, T2, H-T2, etc.) are the 5 main identified mycotoxins families causing a lot of zootechnical issues with or without clinical effects.
Mycotoxins contamination can occur in the field with molds such as the Fusarium species, producing mycotoxins such as Fumonisins, Trichotecens and Zearalenons on the crops. Contamination can also happen in storage with fungi, such as the Aspergillus and Penicillium. Those fungi are linked to Aflatoxins and Ochratoxins.
One mycotoxin can be produced by several molds and one mold can produce several mycotoxins, causing multiple contamination. Nowadays, about all samples having a positive result for mycotoxin presence are in this situation.
Multiple contamination in feed increases the toxic effect of mycotoxins and their impact on animals’ performances. With this kind of toxins, both additive and synergic effects are possible, depending on many external factors.
Their toxicity level will also depend on species, animals’ age and mycotoxins families’ presence. On monogastrics species, we mainly identified impacts on growth performances, reproduction, metabolism and immunity. On ruminants, we identified impacts on reproduction, milk production but also on milk quality.
Raw materials analysis is the starting point of mycotoxins contamination knowledge in each particular situation. Corn, barley, wheat and oats are important substrates, but they are not the only raw materials that need to be analyzed. For ruminants, forages are the main source of contamination which also
Mycotoxins contamination can be suspected by
No physical sign of contamination does not mean no contamination at all. Even good-looking raw materials can have a

In addition, mycotoxins are very stable and resistant metabolites. They can resistant to thermic treatments up to 250°C (such as extrusion, pelletizing, flacking etc.), physical and chemical treatments (such as cleaning,
In turn, these toxic molecules represent a threat for animal species as much as for humans because they compromise animals’ immune system and food safety. To avoid their negative impacts on animals’ performance, they need to be protected by
