Mycotoxins are secondary metabolites of mold growth that are toxic to animals and man. Mycotoxin contamination of foods or animal feeds can occur either pre- or post-harvest. Crops frequently become contaminated with mycotoxins as a result of insect damage, frost, excessive rain, drought, or other damage to the integrity of the crop that allows mold to grow. Not all molds produce mycotoxins, because of this and the fact that these toxins are secondary metabolites, a high mold count does not necessarily mean that mycotoxins will be present. Mycotoxin molecules are quite stable and many are resistant to most chemical or thermal treatments.
Mycotoxin Testing by Venture Laboratories is done by quantitative fluorometric assay, HPLC, ELISA or TLC. Routine tests include: Aflatoxin, Citrinin, DON (vomitoxin), fumonisin, ochratoxin, zearalenone and ergot alkaloids (fescue only).
Concerned about silage quality? Venture laboratories can help! A full service microbiology laboratory can examine lactic acid bacteria, Clostridium sp., Listeria sp., Salmonella sp., E. coli and yeast and mold.
